Dr. Hank McCoy, a mutant scientist who through a serise of experiments, caused the mutant gene within him to swell. This brought about the cat-like/ape like abilities of BEAST, leaving his mind and personality however as unchanged as ever. He is a BRILLIANT, scientist, lecturer, and genetasist, as well as brawler, and gymnast.
Grodd on the other hand, is a rogue scientific prodegy from a lost city of...."Ape city". Lol
Wanting to control all "Ape-dom" he specialised in mind control technology and in many instances tried his luck control the much inferier race: Humanity. However he was almost ALWAYS foiled by the flash, and there lies his un moving vendetta.
His IQ is one of the highest, for HIS race, which is infanantly more mentaly qualified then Humans. His technology, surpasses that of humanities as well, and even some of his own species. His brilliance does not in any way prevent him from crushing the life out of a foe. He is immmensely strong, and a capable fighter among his own people.
Who would win, in an brawl, and who would win in battle of wits.
