Ok posted this two time allready but what the heck, Hank_mccoy is mad. I guess because beast should be stronger.
The McCoy Manifesto
Beast is, or was, supposed to be strong. After his ordeal with the touch of Pestilence and the absorbtion of Infectia's kiss, he was reported to be in the 70 ton range. A response to a letter in X-Factor #33 said that if he were to arm-wrestle the Thing (at the time in his strongest "spiky" form, in which he almost defeated the Mr. Fixit version of Hulk in one of the greatest melees ever recounted) the match would be "more even than you might think."
Lest you think only Louise Simonson bought into Hank McCoy's new brawn, Beast also figured prominently in that year's Avengers annual, surprising Hulk and Hercules with his strength.
Yet every stat sheet Marvel has ever done on Beast says he is as strong "as a jungle gorilla." To recap, in the original X-Men days when McCoy was a human with big feet, he was as strong as a jungle gorilla. Later he experimented on himself at the Brand Corporation and changed into his improved furry form, in which he was as strong as a jungle gorilla
(thit is also the part where beast is fighting Iron man, but I'm not sure he won it was in Amazing Adventures #12-13.
This is what happend
(Tony Stark visited Brand and, because of a crisis, both he and Hank tried to help as super heroes, yet Iron Man mistook the Beast for a villain. From a short distance, Mastermind of the Brotherhood of Evil Mutants watched and planted the illusion of having killed Iron Man in Hank’s mind. The Beast was then easily manipulated into joining the evil mutants, but they failed to recognize him as the X-Man they all had encountered before. Soon, Hank overcame the illusion and left the Brotherhood, after defeating them all by himself.)
After X-Factor's inception he reverted to human form with no apparent change in strength. Then his strength was increased at the cost of his considerable intellect by Apocalypse's horseman Pestilence. This condition was exacerbated by Infectia, leaving the Beast's strength augmented, finally, to the heretofore unreachable heights of the jungle gorilla.
