Knowing that asking for a fourth party character like Hulk Hogan would probably be out of the question, I decide to ask for the next best thing and ask for one of the most known Hogan imitations, available.
Considering that a wrestler might be pretty interesting to join crusade, as my assumption for them would be either specialized in close combat, dealing a whole lot of damage upfront.
Why Muscle Power should join Crusade:
90% of fighting games have a wrestling character, except for the Smash Series. A Wrestling character would add a whole different facet to the game, I believe. Not only that, but he's based on one of the most well know sports icons in the World, Hulk Hogan. Hulk Hogan was the Sports King of the 80's, everyone knew and knows who he was. Muscle Power has everything Hulk Hogan does, his moveset, his hairstyle, even his Japan-used catchphrase. 'I'm number one'

His specials would be along the line of running clotheslines and stuff of the like.
B - Wind up Punch
B Up - Jumps up, grapples(Think Falcon), then Powerbombs opponent to the ground. If used to recover, just tap a button to headbutt them off.
B Side - Running Clothesline
B Down - Big boot
Final Smash - jumps up off screen to crash back down on the map with a leg drop, sending shockwaves everywhere, the closer to him, the more damage and knockback it will gve.
