Like the way Galan debates...with that said...
Nothing short of a Nuke is hurting Wolverine.
Spiderman has the power to damage beings like Superman, Thor, Hulk (and he has the fts too)
Magneto could beat everyone short of Surfer by either opening a black hole around them or boiling their blood.
Nothing short of Galactus is beating Surfer since Surfer has ripped the soul from a being, turned to snow, head butted someone and destroyed moons and countless planets. Threw a blast the size of a star with one hand. Drained powers. The list goes on. He survived super novas, tanked Black holes, stopped time, went back in time. Withstood blows from beings as powerful as Galactus. The list goes on. I bet Galan wouldn't give Surfer 10/10 over Superman (he is clearly debating strictly off of high showings), no matter what Surfer is capable of or has done. For some strange reason, when it comes to anything outside of debates like this, Galan tends to debate strictly off comics. Knowing that it doesn't take what he is saying above to hurt Superman or Surfer.
Surfer has tanked black holes and Super Novas...would Galan come in here and say that Superman dishes out those type of attacks, so he would put Surfer down? Hell no because consistently, even though Hulk has walked through planetary forces with ease, we know it doesn't take that amount of power to damage him ON AVERAGE.
I've seen Galan debate and he only debates like that here.
Also, lol at Goku having to charge up an attack to hurt Superman.
Doctor Light dropped Superman in a single hit and his power output is nothing comparable to Goku.
