Maxima vs Hiro-Kala

Máxima vs Hiro-Kala

Good question; but I think that Maxi has him beat, although I wouldn't be surprised if she'd have her hands full with him.

What happened with Hiro-Kala?

I may be recalling it wrong, but I think that he's in the Microverse.

That's what wiki says too, so you're probably right.

Maxima IMO

Maxima destroys him.
