"Baby" (ベイビー Beibī) is an archetype of cards used by Jim Crocodile Cook in the Yu-Gi-Oh! GX manga. Its only revealed member, "Alligator Baby", is an infantile form of another creature.
The cards are supported by "Reptia Egg" and have ベイビー (Baby) in their Japanese name. Cards such as "Baby Dragon" are not included as their Japanese name uses a different spelling of "Baby".
