Spidermen vs. TMNT
Tobey and Garfield Spidermen
vs.
Leonardo and Raphael from TMNT.
Let's face it, Cap and Bucky are completely outclassed by the turtles, so let's up the game. Now the two top turtles need to take on the two Spidermen.
Leonardo and Raphael both get their standard weapons and about a dozen shurikens each. Tobey and Garfield get unlimited webbing.
Combatants have zero knowledge about each other. All the turtles know is that the spidermen look like red-costumed foot soldiers. Fight to the death.
