...Turn into a big, muscular version of himself. With the use of his Musclecore poison, a toxin used to convert all his fat into muscle, he can grow huge and beefy. This allows him do many things better, including run, lift stuff and punch. However, he's susceptible to hammers and large and heavy bludgeoning objects. In addition, he can no longer use his tail as a weapon. His poison will tense the muscles up of incompatible creatures, but doesn't kill them.
