Digimon Battle Pets
In the V1 Digimon virtual pet, Numemon was the weakest champion-level Digimon, being barely stronger than a rookie, and used his own feces as a weapon. However, if treated with perfect care, and had a win percentage of 40% or more, he would digivolve into the strongest of the three ultimate leveled digimon, Monzaemon (The other two were MetalGreymon and Mamemon). Monzaemon could destroy just about any Digimon with extreme ease. However, they did not live as long as MetalGreymon's, and they could get injured in battle quite easily.
