Suggested by Destroyer Megatron has appeared in many different forms with a variety of energy weapons and close range options. Even his best incarnation wouldn’t be able to keep up with Lazerman’s speed though which is what ultimately gives him the edge here. It’s just hard to keep up with the guy and he can keep on firing his disruption blasts. Megatron has enough durability to last for a while but ultimately he will be blown away. Lazerman wins.
