They did. lol. there power levels fluctuated wildly. That big guy could pin down Invincible with one finger yet Invincible almost beat the lady. Of course it could be differences in gender strength but her and her group were sent to bring in OmniMan so they should’ve been able to at least hold there own against him, but Invincible C’mon. But its a common trope to make the protagonist extremely capable despite being ‘new’ to there abilities relatively speaking. Peter Quill in GOTG defeated his million year old father almost as soon as he got his powers.

There power levels fluctuate wildly in that fight
