MegaGirl is a character I came up with wayyyyy back in 1990.
She is modeled after a superheroine that exsists(ed). Most of you should be able to guess.
These aren't really sketches but they are way back when I couldn't do this stuff on computer.
I was still trying to figure the character out. The "W" will become an "M" like below and ended up spanning her chest.
If I find any of the final costume, I'll post them someday.
