Ha ha ha, can Wolverine beat Superman? I found this to be a silly question; however, I do understand people are going to believe what they want to believe. Here are the facts about Wolverine. Yes! Wolvie has indestructible bones and claws, super healing ability, and last he is an superb fighting ability.
However, Superman, on the other hand, is probability a thousand times stronger and faster then Wolverine. Superman has super senses ( hearing, vision, ext.) Superman can freeze objects as well as destroy objects with his heat vision. Oh yeah, I forgot about his flying ability. Guys and gals think about it Superman has better senses than Wolverine so sneaking up on Superman is unrealistic. If wolverine attack Superman it would be like Neo from the Matrix meaning wolverine would be moving in slow motion, so all Superman has to do is freeze Wolverine and throw Wolvie into outer-space or just throw him into space where he would die due to lack of oxygen.
