Axogaros are the hybrid of a male Mutant Axolotl breeding with a female Xenogaro. Because their chromosome number count are the same, it is possible for the 2 species to breed with one another. A male Xenogaro breeding with a female Mutant Axolotl, however, will simply result a a baby belonging to either species, not a hybrid.
Axogaro's are very strange beings, they mostly look like a typical Xenogaro, but with minor differences. Sometimes these differences can turn out to be major (gills, webbed feet, axolotl tail, etc) One of the first axogaro's to be discovered is Veran, a 4 year old female axogaro from the future, who is theorized to be the future child of Ploxl an Kishiru..
