Cozmo doesn't have a plant name but most if not all other professors do. (Oak, Juniper, Mohn, etc.) Is Cozmo the only exception to this rule? Or did I get it completely wrong and Cozmo is a plant name in a different language?
Thanks, Indi for the sites on Pokémon Professors. Now, the reasoning for Professor Cozmo's name not deriving from a plant species is that he is a meteoriticist, a scientists who deals with meteorites. Bulbapedia's Trivia on Pokémon Professors states that "all core series Professors and Professor Willow (from Pokémon GO) are named after a type of tree.". Also, under the Names category for Professor Cozmo, his Japanese name "Dr. Takao Soraishi" comes from Sora (sky), Ishi (rock), and Takai (high).
Cozmo's name could be based on the Cosmos flower.
Bulbapedia says that it's based on the cosmos, as in the universe, but it could be either.
