If it were me, I'd base it off the original logo somehow
Hm... It'd have to be a female unfortunately, with the red P becoming her hair. The other colors will have to work into her clothes, but the combination of blue, green and yellow I actually can't see working too well on clothes.
I can see it being a battle dress of some sort.
For play style, use the lid of the PS1 as a shield. She could probably pull out throwing discs from it, or better yet the boomerang controller. The PS2 controller can be swung like a flail.
For a special effect, have the PS3's background streams follow her around (like in the intro).
That's actually a cool idea, I like it, especially the character being female. We need more!
She would definitely have some cool intros, outros, etc... But the REAL question is, who would her rival be? PEPSI MAN!?
I was thinking the Polygon Man, sounds like the only one that could fit well with her.
"Hm... It'd have to be a female unfortunately"
Why does it have to be a female "unfortunately"? I'm not understanding that bit.
Sorry about that, I thought up the play style first before the design, then imagining a knight-like image in my head (a really blocky knight whose armor is based on the PS1, PS2 and PS3 XD) But when I decided to use the logo as a base, I realized that it was more suited for a female. Which means my original (and very stupid idea) would have to be scrapped. That line was typed when I came to terms with my disappointment.
But as I fleshed her image in my a bit more I started to like it.
Dang nabbit, you guys got me in the drawing mood again.
This is my take on what "PlayStation" the character would look like. It came out a little Nariko-ish and derivative, but what can ya do. I made her "flail" weapon a PlayStation Move controller, and her shoes are meant to look like PS2s. Surprisingly, the PS logo's colors do fit well in a "battle dress" such as this.
EDIT: Gah, I didn't even realize Nariko also had a headband like that. Excuse me while I plant my head on my desk...
What do you think?
