Boo from Super Mario for the Super Mugen Bros project.
By Shazzo the Hedgehog.

Origin:
Well, after getting into Mugen recently, I instantly desired to make my own character. However,
since I didn't have Photoshop or Paint Shop Pro, & Fighter Factory was a foreign language to me,
I decided I'd start out by editing an existing character. That's when I found CvS Axel by
EasyChar. Then of course there was the palette issue. MakeAct and Pal2act were useless, so I
tried an alternative strategy, using Paint and Photo Express. And it worked! So after
a few hours of editing, I transformed Axel into his current form - Boo.

Why:
Boo is one of the characters for Super Mugen Bros.

Moves: I had a bit of fun with Boo by having him impersonate other characters, sort of like what
Kirby does.
Standing
A/X - Punch
B/Y - Lick
C/Z - Bite

Crouching
SMB uses weapon modes rather than crouches. These moves are stronger but take longer to connect.
Boo's weapon mode is his angry mode.

A/X - Punch
B/Y - Lick
C/Z - Choomper

Midair
A/X - Punch
B/Y - Lick
C/Z - Booigi spin

Specials
Down, down-forward, forward + X/Y/Z - Boorio fireball
Down, down-forward, forward + A/B/C - Booser flame
Down, down-back, back + X/Y/Z - Booigi spin

Supers
Level 1
Down, down-forward, forward, X+Y - BOO! - Boo turns invisible, then jumps out of nowhere!

Level 2
Down, down-forward, forward, A+B - Giga Booser - Boo uses all of his energy to impersonate
Giga Bowser, and releases a large ball of fire. This attack leaves him temporarily exhausted.
