Dr Doom(Fantastic Four) vs Sabastian Shaw(X-Men First Class)

Both have a day of prep. Who wins?

Doom.

What would Doom do to him he absorbs energy?

Well, we don't know how Shaws body will react to cosmic energy (it altered johnny at a molecule level so...). That is a rather unknown factor, but I do know that being grapped by the throat and being carried into orbit or potentially space by Doom, isn't going to work wonders for Shaw.

Doom doesn't have the board here

My mistake I thought it was Doom with the powers of the Silver Surfer.

No that might be to powerful for Shaw.

Ain't no "might" about it
