Man if Pete ever does get married again I'd love to see Mephisto in one of the rows cheering him on, tissue by his tear-filled eyes.
He's sat atop a huge pile of W.M.D.s (Weapons of Marriage Destruction).

Really, Mephisto need not rear his head near Spider-Man again. Just the effects of the deal brought to light would be enough. For instance, ...
Maybe Peter should die inside of Ock's body. With him thinking that he'd wake up again in heaven, only to open his eyes and see he is in hell. He begins to rail to the local demon lords against his fate. Saying he doesn't belong there, that he is not really Otto Octavius. Only for the demons to laugh at him and tell him they know full well who he is. He is not there to answer for the crimes of Doctor Octopus. But because people who make deals with a devil always end up in hell. The demon then pulls out his copies of OMD and OMIT for Peter to read and know are his true history, and that he has to read them over and over throughout eternity as his punishment. And then, to rub salt in his wounds, they tell him he could appeal to Mephisto for another chance at life due to him dying in a body that was not his own. But then he can't, because Mary Jane made him swear to stay away from Peter after the deal was made. So his hands are tied from aiding Peter now due to MJ's sub-deal. Mu-ha-ha-ha-ha!

Why would Mephisto apear in ASM#700 in any way at all.
He is part of a five year old story that was retconed away,if Mephisto was to be part of another Spidey story,the writers would have not bothered to retcon the OMD story away of the continuity.
Plus major cosmic/mystical villains as Mephisto,Thanos,Doramammu never apeared in more that a couple of stories during the 50 years that Spidey stories have been published.
Which makes sense, street level super heroes against major cosmic villain is a bit silly.
