Tentoumushi 8.0 from Season 5.0.

Tentoumushi (Mecha Tentoumushi in Season 2.0 and 3.0) was a lightweight robot that fought in every lightweight competition of BattleBots. The brainchild of teenager Lisa Winter, Tentoumushi featured a very unique weapon, a servo-powered ladybug sandbox lid that dropped onto other robots to "smother" them. The inside was sometimes accoutered with a circular saw or grappling hook to cause damage to its opponents. The chassis itself was quite small, a flat v-shaped body that housed the servo and drive wheels. Tentoumushi had a decent combat record as it won at least one fight per competition, but its recognizable design and creativity made it a crowd favorite and frequent beneficiary of screen time. Its best performance was the Long Beach competition, where it won three battles and reached the semifinals. Lisa's father entered Season 1.0 and 2.0 of BattleBots with middleweight Spin Orbiting Force.

The Season 1.0 version made a brief appearance in Series 3 of Robot Wars, beating the middleweight A-Kill in a one-off "War of Independence," and fighting with all the middleweight robots in an exhibition rumble.

Lisa's father Mike Winter had previously won the 1994 Robot Wars middleweight competition and finished Runner-Up in the same competition in 1995 with his robot X1.

Tentoumushi was so-named because it's the term for "ladybug" in Japanese.

It would eventually return for ABC Season 2 as the heavyweight robot Mega Tento.
