A group of Cybertronians from Beast Wars: Transformers whose alternate modes are a combination of two completely different animals. Created upon the destruction of the Vok doomsday weapon, the Planet Buster, which released a powerful quantum surge that impacted a number of stasis pods orbiting prehistoric Earth. These pods crashed onto the planet, their damaged DNA scanners scanning two animals instead of one and splicing them together into the protoforms' new hybridized alternate modes.

Also related to the Transmetals and Transmutate, as their mutations are also a result of the aforementioned quantum surge.
