Ok...I have a wicked cool plan (I'm smiling ear-to-ear just thinking about it). Here's the team.
Asgardian Destroyer (the Skyfather level)
Thor (he can control the Destroyer)
Martian Manhunter
Absorbing Man
Hulk
The Doctor (Authority)
Mimic
Wolverine
Pretty weak team you say. And right now, I would agree. But stay with me...
Absorbing Man goes to the hardware store and absorbs about every different substance known to man. He also stops at a computer store, and absorbs the properties of it as well as all of the the information he can find on the Internet (he has done this before...after ward he beat most of the Avengers easily). So he can think at the speed of a high-speed computer (we'll say, to be modest, a few hundred thousand calculations and thoughts a second)
Now everyone on the team lines up in front of Absorbing Man. First he absorbs Thor and his Class 100 strength (this doesn't hurt his teammates mind you) and also the magical properties of Thor's hammer. He then absorbs MM (so he's a telepath), Wolverine's claws (so he can change into adamantium) and also Wolvie's blood so he can heal really fast. He absorbs the Hulk, his strength, and his ability to get stronger with rage. Just for good measure he absorbs the magical properties of the Destroyer. So he's a 100+ strength level magical telepath who can change into adamantium at will and heal almost instantaneously (Hulk and Wolvie) and thinks at a speed infinitely faster than normal.
Next it's Mimic's turn. Mimic can absorb up to 5 people's powers, but only 50% of them. He absorbs Thor, Wolvie, MM, and the Hulk...so he's 50% of all of them. But then he turns to Absorbing Man. They both smile. 😈 Abosrbing Man is everyone (minus the Doctor..all of his powers might be hard to absorb and control) and Mimic absorbs him. So now Mimic is 100% of the aforementioned people and is also an uber-badass 100+ strength level magical telepath who can change to adamantium and heal and think much faster than normal (though only 50% the speed of Absorbing Man...but it's still hella fast).
Now we're almost ready. Wolverine's usefulness is done so he goes on a picnic while the others prepare for the fight. MM projects some hideous and disturbing thoughts into the minds of Absorbing Man and Mimic, so they're in full rage mode and a few times larger than normal (and adamantium!).
They each have their roles...Hulk is a meat shield, and easily the most worthless on the team. The Doctor will have a shield around entering the fight to protect against any quick attacks. MM will shield them telepathically and stay at a distance. Absorbing Man, Mimic, and Thor (now in the armor, which puts him slightly above Odin level) are the physical guys. They go for Apocalypse first, before he can get too powerful and big. Some adamantium 1000-class punches and a few Destroyer-enhanced Godblasts later and Apoc. is a puddle.
MM and the Doctor have been holding the physical/telepathic/magical shields up for a while while the brute squad takes out Apoc. (Absorbing Man and Mimic have been helping with the telepathic shield). So now the brute squad (easily a match for probably even a prepped Thanos) goes for Thanos and MM and the Doctor are left to deal with Dormammu.
The brute squad beats Thanos an inch from his life and then send him into the next galaxy. Meanwhile MM and the Doctor have their hands full with Dormammu. Doctor is easily Dr. Strange's equal, and probably more powerful, but Dormammu might have him trumped a bit. But now Mimic drops Hulk's rage and absorbs the Doctor. Absorbing Man does the same. And though they aren't as practiced with magical arts as the Doctor (or Dormammu) the three of them combined wailing on Dormammu with all of their magical know-how will be enough to contain and put down Dor. Once the battle is over, the Doctor draws his power together for a while and then sends Dormammu to a pocket dimension that he'll have some trouble getting out of.
Woot! Let the dissenting opinions begin!
