Black Tom Cassidy (KYTRIGGER) bio
vs.
Agatha Harkness (HIPPY FASCIST) bio
Okay, interesting match, and one that will be decided by teh fact that Black Tom is a lunatic.
Powers:
Black Tom is basically a giant living plant organism. He looks like a tree, and can bond with all forms of plant life and control them. This makes it extrmeely difficult for him to be killed or seriously injured since he is in so many plants at once. He can also siphon the life energy out of his oponents "by sticking special tendrils into their body cavities". i will be the first to say that doing that to Agatha Harkness is just a terrible terrible image.
Agatha Harkness is a witch. She can cast a bunch of spells. She is also very old.
As for Prep time, neither will probably get any info on the other. And I am sure both know of Asgard, but I don't believe either have really visited the place.
For the fight, Black Tom would instantly start merging with all the plant life and foliage in Asgard (which from the most part, looks to have quite a bit of plant life.) A big factor here is that Asgard is a magical place. It is very likely that by merging with the plants from Asgard, that Black Tom could easily have some sort of magical power boost. I'm not saying he would be all powerful or anything, but a certain resistance to magic is VERY possible, since that seems to happen to everyone else that absorbs magic in the MU.
Now Black Tom will start going after Agatha righ taway, but she won't be helpless. She probably knows some decent spells, but an important factor here is that she won't go all out and try and kill Black tom. It's just not in her nature. It would also be pretty impossible to teleport him somewhere else, since he is basically everywhere. He surrounds her with his roots and all, and can't be pinned down to one location very easily.
Also, Black Tom is a vicous bastard. He will not hesitate to kill an old lady. He has no real sense of honor here and isn't looking for a fair fight. If he can, he will lurk in the trees, and strike her dead from behind.
Another important factor here is that Agatha is old. Very old. While she defiantely knows some spells, all magic taxes a person physically. And generalyl, the more powerful the spell, teh harder it is on the body. She simply doesn't have the endureance to constantly be casting fire spells at Black tom only to have him appear in yet another tree. At a short amount of time, she would grow very tired and Black tom would kill her.
Black Tom has too much of an advantage by beign abele to be almost everywhere around her, and not having to care about taking a life.
Winner- Black Tom Cassidy
