Metal Robotnik

Robot vs. Robot

Snively used to Metal Robotnik and he manages to force Megatron to drop one of his swords. Snively takes to the air in an attempt to increase his advantage, only for Megatron to kick him into a bridge. Unfazed, Snively uses some air-to-surface missiles to stun Megatron. The two fighters end up at a standstill after the two fire their weapons directly at each other simultaneously. Snively tries to fire one last shot, only for Megatron to get the draw. With one last shot, Megatron destroys Snively's mech, leaving the minion writhing at his feet.
