the simpson teory makes sense

The most logical thing would be that Iron Fist emulates Murdock's initial "man in the mask" look and eventually Hellcat does too.
Now I haven't seen any Iron Fist footage so I don't know what his outfit DOES look like. (I avoid trailers and such of things I already know I'll check out.)
"Need" is just a fiction. As is "should", "must", "value" and "importance".

No. In the MCU version, it looks like she will get her powers from that IGH serum/pill.

That depends on how they go with it. In the comics the Avengers basically gave her the old suit-with-gadgets of Greer Nelson (from before she was Tigra) but the thing is, most of Greer's abilities didn't really come from the suit, that was softly retconned for Hellcat.
I suspect they'll go with Trish just gets a more permanent version of Simpson's pill-powered abilities (like maybe she takes pills to counteract the mental side effects of arrogance etc.) or something.

that make no sense, she get the powers, she got the suit

I hope she goes for the spandex after getting her powers.

i hope so

Maybe not the first season, second time around sure.

lol. i want her in latex costume

Yeah that was a good scene.

When she was riding the idiot Simpson. She had the most beautiful orgasm face I've seen.

I just wanna see her in the throes of sexual bliss again.
