CUAD (pronounced "Cue-Add") the Unmerciful was a heavyweight competitor built by Matt Ulrey that competed in Season 4.0 of BattleBots. It was a dark red robot armed with two lifting arms that could also be used as a clamp. It didn't perform well in its only season, losing its first and only fight against The Matador.
CUAD the Unmerciful's only fight was against The Matador. Both robots strafed around each other for a while, until The Matador found an opening and catapulted CUAD into the air, destroying one side of CUAD's drive. A few more flips up and into the wall, and a big push into the spike strip, and CUAD tapped out. This eliminated CUAD the Unmerciful from the tournament.
