Tornado: "Now who's a child, Baldy!"
Saitama: "Well, You may have the body of a woman, but inside your still a little brat"

Maybe Blizzard could use her smallness to try and make Saitama join her gang now.

She herself could do it if she was a biokineticist (also known as Egoists) master race. Picture would at least require Mind Swap (Telepath, IIRC). So far she's just a kineticist peasant, right?

I like those two schools because their powers are downright horrifying. Making rocks fly and burn subjects with your mind might look cool and edgy, but you know where the money's at? It's with the ones who can fuse like crystal gems, fission so they can make out with themselves and make your seed germinate within the target (Mind Seed, if the target isn't aware of the jig, in one week they become another instance of you. If you have some Egoist capabilities, you can even reshape it. I guess this power isn't used often to avoid ME HOY MINOY scenarios).

You can also party as hard as you can (as Egoist), just take five to think about your (awesome) life choices, once your magnificent body-and-mind is done with negating all the drugs, booze and STDs from last night, high-five yourself.
