Dark Beast is basically the same as Beast but less smart. Gon has a nen sword which could beat him in a second. Dark Beast can’t match up against Gon. Gon also has a super punch. Gon wins.
Spikeman has spikes that can hurt even the best Leagueman. Leagueman can throw a mean pitch, but it might bounce off of Spikeman’s needles, or just pop. Spikeman wins.
This is tribute to Dr No. Vegeta is arguably the strongest Saiyan in the world. James Bond is a good agent, but at best he’s still human. Also James Bond smokes, so he could die of cancer during the fight. Vegeta wins.
Skullman has speed that can rival even the better navi’s. Some would say he’s even faster than LAZERMAN V3. But that’s just speculation. Leagueman could throw a pitch, but it would miss. Skullman wins.
Ichigo is one of the world’s greatest swordsmen. He has Getsuga Tenshou. Mephiles has dark balls of energy and an energy sword that can pierce hedgehogs. He also has a super form. Mephiles wins.
Of course right now Ichigo’s too tough for Mephiles. Ichigo wins.
Searchman has a scope gun. With it he can shoot the balls that Leagueman shoots. Searchman also has cross fusion. That can take out even the most deadly of navi’s. That includes Leagueman. Searchman wins.
You can’t call this anything, but a blowout. Ignoring that Ichigo can turn into a soul reaper he can take on Leonardo in his PJ’s. His hand to hand combat would easily beat him. Poor Leonardo. Ichigo wins.
Noodleman has noodles that let him shapeshift into whomever he pleases. Of course he is unable to change his emblem. Leagueman throws a mean pitch, but Noodleman can fight. Noodleman wins.
Mephiles has dark powers that are a force to be reckoned with. Carnage is a symbiote like Venom and can make weapons, but that is no match for one such as Mephiles The Dark. Mephiles also has a super form. Mephiles wins.
Metalman can use his metal to take down Leagueman once and for all. If Leagueman could only dodge it, but he can’t so his only hope is to shatter it with his baseball. No dice. Metalman wins.
