OH MY GOD THE FEELS. His mama died so a ditto turned into a charizard to take care of him until he could protect himself ; <--- Or Ditto is actually his dad, and his mom was the Charizard in the relationship
Kingdra might look like an old seahorse, but he's a dragon and don't you forget it! In his pokedex info it says Kingdra can create whirlpools, and he was the dragon pokemon ever. He looks like an ancient dragon, too. Just crossed with a Horsea.
