Uhhh, Doom?? Neither Logan or Victor have the mental capacity to even process who Doom is... especially Creed. I love Sabretooth but he aint the brightest bulb in the box, especially sinces hes all animal now. Logan is a great fighter and tenacious warrior and he may get lucky in CQ but they'd both have to go through a crap load of castle defenses and not to mention endless Doombots, then Doom himself. I just dont see it happening.
not even... Doom casually dismisses the pair as non-threats and swarms them with Doom-bots as he watches on while watching a show performed by gypsies.
