Rodan is a lot larger and has matched Godzilla in combat, a single Gyao gets murdered by Gamera easily, especially if it's Heisei Rodan, that version has crazy lasers comparable to godZillas atomic breath.
Spider-Man has faced guys like this before and come out on top. Spidey sense eliminates stealth, Spidey is fast enough to dodge gunfire, Spidey is physically stronger than anyone Either Big Boss or Snake has dealt with. Spidey wins
Both crossover games decided to fuse their heavy hitting enemies so I think putting these 2 in a battle makes sense. Who wins in a battle for supremacy. fight takes place in New York City and as a rule Dark Kahn cannot be infected with the Sigma Virus.
Catwoman has the skill and the speed to take down Casey, He is durable to be sure but Selina can wear him down. Her whip gives her a range advantage and Casey isn't throwing out anything she hasn't seen before. Casey won't go down easy but he will go down.
So with the drop of the second fighter pack trailer for Injustice 2 I thought having a battle royale between the fighters would be fun. Black Manta, Hellboy, and Raiden in a 3 way fight. Arena is the rubble landscape from the trailer and everyone starts 30 feet from each other. All are in character. Manta has his typical equipment, Hellboy has his Good Samaritan pistol, Raiden has access to his war hammer and staff.
