Suggested by Destroyer Robin did get a lot of super powers at one point which I remember was pretty fun to follow. He could effectively do anything and had few limits. That said, he would still be completely overwhelmed by The BioLizard in a fight here. That Kaiju monster could spam tons of different energy blasts all at once and even use them as a barrier. Robin can try to fly through them but the accumulated damage would be too much and he won’t be dodging for very long. No matter how you slice it, that’s game over. The BioLizard wins.
