Son of Whyachi s8

Son of Whyachi's Discovery Channel Season 3 appearance.

Son of Whyachi is a competitor on BattleBots built by Team Whyachi as a lighter version of their superheavyweight robot Whyachi. It originally competed in Season 3.0 as a heavyweight, where it claimed the championship. However, after new rules decided that its unique drive system (a set of "feet" that "shuffled" along the ground) did not constitute the weight bonus given to walkers, it moved to the superheavyweight division. It was very successful in BattleBots, winning the Season 3 championship against BioHazard. Unfortunately, it never relived its Season 3.0 success, losing very early in Season 4.0, but making it to the round of 16 in Season 5.0. It also had a lightweight version called YU812 which competed in the final two seasons. Son of Whyachi returned for the NPC Charity Open as Nitro SOW.

Whyachi was a word coined in the team's shop that meant "to bring someone down hard and to inflict massive amounts of pain or damage", which certainly describes the robot well.

Builder Terry Ewert applied for Robot Wars: Extreme Warriors with Son of Whyachi, but was turned down, most likely due to concerns that the robot would cause excessive damage to the house robots and due to copyright issues with BattleBots.

The chassis of Nitro SOW still exists today and is put on display every year at the annual Mecha Mayhem tournament, alongside its teammate Falcon.

Son of Whyachi was revived for the second season of ABC's show. The main changes to Son of Whyachi this time around are that the weapon bar is mounted lower and it is now equipped with a small wedge. Early in this new Son Of Whyachi's development, it featured tracks and it would've been the only to have used all three types of locomotion.

After Son of Whyachi had finished competing in ABC Season 2, the team listed the body on eBay in anticipation of a third season, selling it for $1,525.

Season 3.0

Son of Whyachi sf01

Son of Whyachi before Season 3.0.

Son of Whyachi's first match in Season 3.0 was up against Shaka. Just before the match though, Team Whyachi were having an electrical problem with their robot that took them 25 minutes to fix. When the fight eventually commenced, Son of Whyachi easily tore off Shaka's protection and ripped the lifting arm and front wheels clean off, although Shaka continued moving. Shaka continued to drive and managed to disable Son of Whyachi's hammers, reducing the fight to a pushing and shoving match. The fight finished with Shaka pinning Son of Whyachi against the spikestrip just as the buzzer sounded. Both robots had survived to the end and Son of Whyachi won a 29-16 judge's decision. This win put Son of Whyachi to the TV rounds, where it faced Crabmeat.

Crabmeat takes a massive hit from Son of Whyachi.

Crabmeat took several deadly hits from Son of Whyachi's hammers, bending its wheels. Eventually Crabmeat stopped moving and Son of Whyachi won by KO at 1:42. This win put Son of Whyachi to the round of 32, where it faced Kill-O-Amp.


Son of Whyachi hits Kill-O-Amp's right wheel.

In this fight, one decisive blow to Kill-O-Amp was all Son of Whyachi needed to immobilize the then-charging robot, as it destroyed its kill switch on contact. Kill-O-Amp was counted out and Son of Whyachi won by KO at 49 seconds. This quick victory put Son of Whyachi to the round of 16, where it faced the feared Nightmare.

Sowvsnightmare sf01

The infamous hit between Son of Whyachi and Nightmare.

This battle was over quickly as Son of Whyachi and Nightmare moved slowly towards the center of the BattleBox. Nightmare attempted to line up its blade with Son of Whyachi's hammers but got lifted around by the hellraisers as Peter Lamberson hit the wrong button. Then, in one amazing hit, Son of Whyachi sent Nightmare flying, its wheels torn off, into the corner of the BattleBox. Nightmare was destroyed and counted out. Son of Whyachi won by KO at 48 seconds and advanced to the quarterfinals, where it faced MechaVore.

SOWvsMechaVore sf01

Son of Whyachi tears a side panel off of MechaVore.

For this fight, MechaVore fitted a panel on one side with an embedded barbie doll and glued its battery on top. When the fight started, MechaVore and Son of Whyachi avoided each other for a while before MechaVore drove past and had the added panel torn off. MechaVore crashed into the wall but recovered and drove away. As it did, Son of Whyachi clipped MechaVore. MechaVore attacked Son of Whyachi but was repelled and sent across the BattleBox. MechaVore drove at Son of Whyachi again and managed to hit it without being repelled. The next attack from Mechavore saw it crash into the wall. After moving away from the wall, MechaVore attacked again, hitting Son of Whyachi but getting repelled by Son of Whyachi. Son of Whyachi started to move out of the blue square only for MechaVore to attack it and stop the cage, shearing a tooth from its own weapon, leaving driver Robert Lawrence to power down the weapon. MechaVore attacked again but drove onto the cage because of the killsaws. It was clear that the cage had broke and Son of Whyachi was shoved around before MechaVore pushed it past the entrance ramp towards the pulverizer. As Son of Whyachi freed itself, MechaVore made a sharp turn to line itself up with Son of Whyachi but hit the spikestrip and unplugged its receiver, causing it to stop moving. Son of Whyachi escaped the pulverizer and won by KO. This win put Son of Whyachi to the semifinals, where it faced HexaDecimator.

SOW vs Hexy D SF01

The aftermath between Son of Whyachi and HexaDecimator.

As the fight started, HexaDecimator charged at Son of Whyachi and had armor on the left side damaged. A couple of attacks later, the front left panel was torn off. HexaDecimator charged at Son of Whyachi again but the flipper got caught on Son of Whyachi's cage, which resulted in a time-out to separate the robots just as Son of Whyachi was moving HexaDecimator to the pulverizer. When the fight resumed, HexaDecimator was not able to move, possibly due to the battery wire being pulled out when the robots were separated, and HexaDecimator was counted out. This advanced Son of Whyachi to the final.

Fajb battlebots 06 jul2012

The initial hit between the two finalists, causing a shower of sparks.

Son of Whyachi advanced to the heavyweight finals, where it faced off against BioHazard for the Giant Nut. The fight began with Son of Whyachi being charged at by BioHazard, but Son of Whyachi had already got its cage up to full speed. The resulting hit tore off BioHazard's front left skirt and sent BioHazard spinning across the BattleBox floor. Son of Whyachi was rammed by BioHazard once more, but Son of Whyachi promptly threw BioHazard across the BattleBox again. Son of Whyachi's weapon had lost one of its red support rods at one end as a result of this second hit. As a result, Son of Whyachi got stuck at the spikestrip with its body spinning at full speed, allowing BioHazard to lift Son of Whyachi into the pulverizer. Once Son of Whyachi escaped, it was pushed by BioHazard into the pulverizer further, where it got pounded for 30 seconds. Son of Whyachi was then lifted into the BattleBox Lexan, nearly getting overturned. However, this hit seemingly incapacitated BioHazard, as it did not move for quite a while. During this time, Son of Whyachi freed itself from the corner of the BattleBox and spun its now-unstable blade back up to speed. SOW then ripped off the entire right-side skirt of BioHazard. The referee began counting out BioHazard, as it had stopped moving, but just as he reached 7, BioHazard recovered and drove back into the center of the BattleBox. Son of Whyachi then debilitated BioHazard's entire right drive system following BioHazards frontal assault, leaving it spinning in circles. This time around, BioHazard was counted out, leading to booing from the crowd. However, since BioHazard was still mobile on one side with 10 seconds left on the clock, the KO was changed to a judges' decision. Son of Whyachi won on a 29-16 judge's decision and became the new heavyweight champion.

Son of Whyachi didn't participate the heavyweight royal rumble at the end of the tournament most likely due to damage from BioHazard during the heavyweight final.

Season 4.0


Son of Whyachi's Season 4.0 appearance.

Son of Whyachi was moved to the superheavyweight division, where it fought the newcomers Swirlee. Less than two seconds into the match, Son of Whyachi spun up to gyroscopic speeds and tilted off balance. Its spinner struck the floor and it leaps into the air, bouncing uncontrollably into the corner. It ripped a piece off of the screws, and came to a stop in front of a pulverizer. Swirlee edged it onto the pulverizer, which crumpled its body. After just 39 seconds in the BattleBox, the champion's return was over. After the match, the team explained that they raised the hammers on the spinner, and had unbalanced the weight distribution in modifying the frame and in their rush hadn't cut down the last hammer before the fight.

Son of Whyachi is fitted inflatable hammers before the consolation rumble.

Son of Whyachi later came back for the consolation rumble with inflatable hammers. It didn't perform well because it took a hit from Dreadbot, which damaged one of the three red support rods in the weapon, leaving Son of Whyachi barely stable. Odin II moved in and caused Son of Whyachi to become unbalanced and hit Atomic Wedgie. Also, it couldn't move because the drive electronics weren't working and it became a stationary hazard. In the end, Son of Whyachi lost out to Odin II and Atomic Wedgie.

Season 5.0

Son of Whyachi SF02

Son of Whyachi's redesign for Season 5.0.

For Season 5.0, Son of Whyachi was completely rebuilt with a new hammer setup, new design and a new set of wheels. Due to being a former champion and competing in last season, Son of Whyachi was allowed to skip the preliminary rounds of Season 5.0, where it eventually fought Steel Reign. Before the fight, the Steel Reign team had converted Steel Reign into a ramming robot

SOWvsSteelReign sf02

Son of Whyachi rips off Steel Reign's side panel.

In the match, Son of Whyachi started spinning its hammers and Steel Reign gets hit a couple of times. Steel Reign tries to drive into Son of Whyachi again to stop its spinning hammers, but it was having steering problems and Son of Whyachi kept hitting Steel Reign multiple times. Steel Reign brushes up against Son of Whyachi with its side, allowing small pieces of armor to be tossed around the BattleBox. Then a big collision sends Steel Reign over to the killsaws and Son of Whyachi goes sliding into the base of a screw on the other side of the BattleBox. Steel Reign goes straight at Son of Whyachi, but Son of Whyachi escapes and later gets caught on the killsaws. Steel Reign comes close to stopping its spinning hammers, but as Steel Reign is knocked back by a blow, Son of Whyachi brings it back up to speed. Steel Reign pushes Son of Whyachi into the other base of the same screw. Steel Reign drives into Son of Whyachi again and gets knocked into the screw itself. Steel Reign attacks Son of Whyachi with its spinning thresher and one hit instantly snaps the thresher in half, throwing a big chunk into the corner of the BattleBox. Steel Reign chases after Son of Whyachi, which appears to gently slide away after every collision. Two more hits from Son of Whyachi and now pieces of Steel Reign's armor are coming off. Son of Whyachi hits Steel Reign again and a side panel is thrown off of Steel Reign. Son of Whyachi rams into Steel Reign and sends itself sliding across the BattleBox. Steel Reign is no longer moving properly because from the hit that came immediately before the one initiated by Son of Whyachi, Steel Reign's frame was broken and bent into its tire, making it very difficult to move that side of the robot. Son of Whyachi comes over and starts to attack Steel Reign. Finally, after several additional blows, Steel Reign stopped moving and Son of Whyachi does a victory spin as it was being counted out. Son of Whyachi won by KO and advanced to the round of 16, where it faced No Apologies.

Throughout the match, Son of Whyachi was unable to reach its weapon's maximum speed due to a bad battery. In the end, No Apologies won on a close 24-21 judge's decision and Son of Whyachi was eliminated from the tournament.

BountyvsSOW npc04

Nitro SOW gets flipped by Bounty Hunter.

Unfortunately, Nitro SOW never got its spinning hammers up to full speed and Bounty Hunter went straight at Nitro SOW. Bounty Hunter tried to flip Nitro SOW from the left side, but it missed. Bounty Hunter immediately tried to flip Nitro SOW again from the front, but misses again and Nitro SOW pushed Bounty Hunter against the corner of the arena. After this, Bounty Hunter almost flipped Nitro SOW and it tried to flip Nitro SOW once again, but misses. After more missed flips from Bounty Hunter, Nitro SOW tried to push Bounty Hunter, but Nitro SOW couldn't and Bounty Hunter flipped Nitro SOW onto its back. Bounty Hunter pushed the flipped Nitro SOW against the corner of the arena and Nitro SOW was counted out. Bounty Hunter won by KO and Nitro SOW was now in the loser's bracket, where it faced Psycho Splatter II.

This match was rather boring as both Nitro SOW and Psycho Splatter II were having driving issues. After a few small nudges between both robots, the time ran out and Psycho Splatter II won on a close judge's decision. This meant that Nitro SOW was eliminated from the tournament.

ABC Season 2

Son of Whyachi BB2016

The brand-new edition of Son of Whyachi which competed in Season 2 of the ABC series.

Likely due to Warrior Clan's re-entrance into this series, Son of Whyachi was forced to compete in the preliminary melees which would decide the final four entrants into the main bracket. In its three-way melee, it faced 5-way clusterbot Creepy Crawlies and flipper UltraViolent. In the match, UltraViolent never moved, so Son of Whyachi simply spun up its weapon and began seeking out its opponents. It eventually hit one of the Creepy Crawlies, obliterating it and knocking it across the floor, hitting another one of the Crawlies in the process. Son of Whyachi then hit another part of the clusterbot, ripping it open and causing smoke to pour out of it. It then began attacking the immobile UltraViolent, knocking it around a bit but not doing major damage, before both inactive robots were counted out. Son of Whyachi won the match by KO at 1:16 and advanced to the round of 48, where it had a rematch with Chuck Pitzer's Ghost Raptor.


Son of Whyachi breaks Ghost Raptor's right drive pod loose.

Before this match, Son of Whyachi swapped out its wedge front for the mini wedge spikes. In this match, both robots approached before the initial hit from Son of Whyachi stopped Ghost Raptor's weapon. Ghost Raptor continued to approach but Son of Whyachi scored a big hit, sending both robots flying but not dealing much damage. After another big hit from Son of Whyachi, Ghost Raptor finally got its weapon back up, but one of its two front wedge skirts became jammed backward, leaving its blade unable to spin. Ghost Raptor then started having drive problems as its right side drive chain was twisted. Son of Whyachi's minibot got underneath Ghost Raptor, leaving Ghost Raptor unable to move and allowing Son of Whyachi to strike again. The first of Son of Whyachi's hits did little but the second strike sent Ghost Raptor flying, rendering it immobile. Ghost Raptor was counted out, leaving Son of Whyachi to win by KO. This win put Son of Whyachi into the round of 32 with its No.6 seeding, where it faced the No.27 seed Poison Arrow.

Son of Whyachi is sent high into the air.

Son of Whyachi and Poison Arrow managed to get their weapons up to speed. Poison Arrow turned and took out Son of Whyachi's minibot as Son of Whyachi advanced.

Poison Arrow continued to attack Son of Whyachi while it was being counted out. Poison Arrow won by a surprising KO at 58 seconds and Son of Whyachi was eliminated from the tournament.

Discovery Season 3

Brutus overturn SoW

Son of Whyachi is flipped onto its top

In its first fight of the season, Son of Whyachi had to fight Brutus. In the beginning of the match, Son of Whyachi started spinning and Brutus went right straight at Son of Whyachi. This left with a big impact between both robots and Son of Whyachi crashed against the corner of the BattleBox. After another collision between both robots, which also spun Brutus around, Brutus got its spinning disc underneath one of the hammers of Son of Whyachi and tossed it onto its back. Brutus backs away from the flipped opponent and moved toward the center of the BattleBox. Son of Whyachi was being counted out and Brutus won the match by a quick KO, giving Son of Whyachi its first lost of the season.

Next for Son of Whyachi was Monsoon, which had come off a pretty decisive win over Petunia. When the match began, things were doing okay for both robots but Son of Whyachi delivered the first hits, the latter of which sending both robots into opposite corners. Both robots recovered before Son of Whyachi was sent straight up into the air but landed upright. Additionally, this hit had disabled Monsoon's weapon, allowing Son of Whyachi to move in for another attack, which tore off a front armor panel from its opponent. The final hit knocked out Monsoon by rupturing the battery and leading to the arena filling with smoke. Monsoon was counted out, giving Son of Whyachi the win by KO.

Up next for Son of Whyachi was End Game. This match got underway relatively quickly as there was little maneuvering from either bot before Son of Whyachi collided with End Game's weapon, sending itself flying into the lexan, tearing into the 1st layer before on top of the mount for the screws. As it worked to get off, End Game wasn't moving and still wasn't moving by the time Son of Whyachi freed itself. End Game was counted out, giving Son of Whyachi the win by KO In just 43 seconds. The selection committee deemed Son of Whyachi's record to be enough to bring it into the top 16 where it faced Donald Hutson and Lock-Jaw.

When the match began, Son of Whyachi approached and got its weapon up to speed before striking Lock-Jaw's rear shield and throwing both bots backwards. Both robots recovered and Son of Whyachi attacked again, hitting Lock-Jaw's shield once more and being deflected away. This repeated a few more times until smoke began to pour out from its weapon, reducing the match to a pushing match. Son of Whyachi took attacks from Lock-Jaw, whom had now turned to face it with its primary weapon but the attacks didn't cause any major damage. Son of Whyachi was thrown onto the arena screws but escaped and managed to get under Lock-Jaw briefly. Time ran out and the judges awarded a unanimous 3-0 decision to Lock-Jaw, eliminating Son of Whyachi from the tournament.
