I decided to try and translate Spider-Man's UMvC3 moveset into a smash moveset because I was bored.
Jab- His light, medium, heavy combo.
F-Tilt- Spider-Sting, a rising uppercut move. F-tilt can be inputted again to get Spider-Bite, which has Spidey follow up by punching the opponent back into the ground. This can't be used midair. Spider-Bite is a meteor smash.
U-Tilt- His special attack (Which is basically just a launcher in UMvC3)
D-Tilt- His crouching light, medium, heavy combo.
Up Special- Web Zip, which is shooting a web that pulls Spidey forward. This can be angled diagonally or straight up.
Neutral Special- Web Ball. He shoots two web balls forward that instantly web the opponent if they hit, but they don't stay webbed for very long. This shoots diagonally if it's used midair.
Side Special- Web Throw. He shoots a web forward and then throws the opponent the other direction if it attaches to them. This can't be used midair.
Down Special- Web Swing. He attachs a web to an invisible ceiling and swings forward with a kick. Similar to the swing kick move in Insomniac's Spider-Man games, just shorter in range.
Neutral Air- His air light attack.
Up air- His air medium attack.
Forward air- His air heavy attack.
Back air- His air heavy attack, just in the other direction.
Down air- His air special attack.
Forward Smash- A shorter version of his Crawler Assault hyper, having him rapidly punch and kick the opponent. Solid kill power and racks up 15% damage unstaled if all the attacks hit.
Up Smash- A stronger version of his up tilt.
Down Smash- A stronger version of his crouching heavy. He does the attack on both sides.
Final Smash- Maximum Spider. He jumps into the air before launching towards the opponent. If he hits them it goes into a cinematic hyper where Spidey rapidly attacks, trapping the opponent in a giant web as he does so. He then finishes it by stomping on the opponent from above, sending them flying downward.
His taunts are all the same animation with one of the 3 voice lines he has in UMvC3.
Up Taunt- "Does what a Spider can"
Side Taunt- "Looooser!"
Down Taunt- "Dude, you suck!"
Only move I couldn't get into here was Ultimate Web Throw. All I could really see it working as is as a different final smash.
