Are you kidding??? Mephisto has showed enough power to fight freaking Galactus to a standstill. The only way I see Loki having a chance here is if he tricks or outwits Mephisto, but that would be pretty damn hard because Mephisto's probably just as smart as Loki.
"how does he get through lokis force field even thors enchanted hammer has trouble doing it "
Galactus tried to scare Mephisto at first with his size, which caused MEPHISTO to grow into his TRUE size and power and fighting GALACTUS to a standstil. GALACTUS!!!!!!!
Mephisto casually jokes that he could bust a galaxy.
Mephisto screws up the Silver Surfer.... BAD.
Mephisto states that the surfer's power cosmic is like a yelping puppy compared to Mephisto's might.
" @why so serious: Post the scans where Galactus is shown to be so hungry that he begins devouring Mephistos realm. Go ahead. "
The reason he was so hungry was because he used up all of his energy during his fight with Mephisto.
Mephisto and his realm are basically the same entity, and he is virtually omnipotent while in his home turf. So there is no way Galactus could overpower/destroy Mephisto. But he could EAT Mephisto's realm and that is when Mephisto got concerned. So he simply booted Galactus out of his realm. I do believe that if the measures, whatever they were, were not taken, Galactus could have consumed Mephisto's realm and thus Mephisto himself. That's the difference between Galactus and more magical beings like Mephisto and Odin, their powers are for the most part tied intrinsically to their domains. Galactus on the other hand, maintains a constant powerlevel regardless of what dimension he is in, provided of course that he is well fed. On neutral ground (Earth) neither of then could hold a candle to Galactus.
Mephisto is more sinister than Loki but that doesn't necessarily make him more cunning. They are both selfish sowers of chaos, so I generally find them to be on the same team, rather than at odds. I do agree that Mephisto is probably more powerful than Loki, but I wouldn't want to underestimate Loki, because that is when he most dangerous. Supposedly Dormammu, who has been said to be as powerful as Odin himself, has said that Loki's powers were only slightly less than his own. Mephisto himself has been outplayed by Thanos, who is inferior to him in terms of raw power. The way I see it, given their personalities, it would not be a battle of magical prowess between Loki and Mephisto. It would be a battle of the mind, and I find no cause to believe that Loki is Mephisto's lesser in this regard. It would really come down to who stands to win or loss most in the outcome of their conflict.
Ok Loki is below Skyfather. He is about as equal as Thor.
Mephisto is slightly above skyfather and is closer to Elder God status. The only way to beat Mephisto for any character below this is PIS. I mean Loki can beat Mephisto, but is has to be by plot, not by his powers because Loki is very much weaker than Mephisto by a long shot.
