So you're stating that Kid Buu was a mutant with a difference appearance who altered his appearance based on what he ate, and the altered appearance just happened to exactly coincide with the original form of his species? That's nonsensical bullshit, and I'm rather glad he chose not to introduce that to the DBS universe.

Calling the Frieza family mutants is also a weak link, and doesn't make much sense. Xenoverse as a whole is fairly nonsensical, and shouldn't be introduced to canon.
