sonic is awsome...
let me try...
1º match: Mario tries to smash sonic with his butt, sonic just stands there looking down then... MaMa-Mya!!!! mario gets a spine shoved in the ass..(sorry i'll make better on round 2)
2º match: Sonic chooses a fire shield, a ring and bounce bracelet (or wotever)... mario chooses fire flower, wing cap and hammer suit.
Sonic activates the bounce brac. and starts bouncing at marios direction, mario succeeds on dodging most of them but one. Mario gets stomped and buried in the ground with sonic above him. Mario gives the coin punch thing from SSBM, sonic seems impressed. They fight some more, punch, kicks, throws. Mario and sonic are tired, mario uses the fire flower and starts throwing fire balls. Sonic is fast enough to dodge them, mario begins to throw fireballs extremely fast, sonic is tired and activates the fire shield for fire protection. Sonic performs a flaming dash towards mario, blocking fireballs and devastating the field with flames, mario does a triple jump and sonic misses. Sonic sees mario from afar and starts running really fast, creating winds behind him, entering his maximum speed he breaks the sound barrier and starts rolling. When he reached mario, in an instant he reveals the wing cap and starts flying up. Sonic looks surprised and pissed, mario laughs but the blue bur hasn't give up. He tries to hit mario with homing attacks but fails, mario equips the hammer suit and throws hammers at sonic. Sonic while dodging, remembers that he has one last item... a ring...
With a deep breath, sonic aims at mario and throws the ring. The ring gets stuck on marios head... mario is mocking and laughing at sonic, sonic gets his smiley face and in an instant, sonic was in the air with marios head on his hand... (in sonic battle, sonic has an ability which he throws a ring in a certain direction and dashes into it..)
3º match (luigie used a 1up to revive mario): In this match sonic will go with knuckles and mario will go with luigie. Luigie and mario begin to do their acrobatic attacks, sonic dodges and knuckles blocks. Luigie then whispers to knuckles that sonic broke the master emerald, knuckles gets really mad and grabs sonic throwing him against the mario brothers like a hurling fireball. Mario brothers stand defeated and sonic is nothing more than a pile of ashes... so........ knuckles wins?
