P-rex (Ｐレックス Pī rekkusu) is a kaiju created by MosuFan2004.
America was testing their B53 nuke on an unknown island, on that island there were members from Predatorius Rex species, the nuke killed every P-rex except one for some reason, that one P-rex got mutated because of the nuclear energy. The last P-rex wanted revenge. 10 years later, P-rex found New York, he attacked it, destroyed every building he saw. Later America send their tanks and jets to kill the P-rex, they were useless, P-rex used his atomic fire breath and destroyed the military. P-rex destroyed New York and came back to the ocean. 5 years later, America decided to nuke the creature to be sure that the destruction is not going to happen again, America found the creature and sent a nuke to it, P-rex saw the nuke and somehow his fire evolved into a beam, he destroyed the nuke in the air and came back to ocean. After that he joined the good kaiju of Universe 2004 because of memes.
