What do you think, who can beat Juggernaut in a One on One combat?

Hulk for sure,

If the question is who can defeat Juggernaut by removing from the field of play then many heroes have done this, even Spiderman, Hulk, Skaar (son of hulk) etc. If you are asking who could harm or even kill Juggernaut then this list becomes a lot more exclusive.

Hulk can but as mystery020 said there are many more that can kill juggernaut

Spider-Man, Spiderwoman, Thor, Hulk, Skaar and obviously the X-Men

Dr. Strange ? Yeah I think Dr Strange can easily beat Juggernaut. I just wanna see them fight. Is there a comic book series in which they both fight?
