Oh, cool. I guess that means Groudon, Aggron, Totodile, Croconaw, Feraligatr, Mew, Tyranitar, Feebas, Milotic, Steelix, and Onix are dragon type due to their ability to learn dragon type moves.
I'm saying Treecko is as dragon-like as Charmander and Totodile, not that it's Dragon-type itself. Sheesh. How many pokémon you know that learn Dragon Claw, Dragon Pulse, Outrage and even Dragonbreath? Except for Outrage, it's usually the reptilian, menace-looking pokémon that get them (and well, aren't dragons reptilian and menacing anyway?). Sceptile, along with Charizard and Feraligatr, clearly are more draconic than the other starters. And that's a pattern some people had noticed back in the pre-R/S era.
That's why I'm saying it's *possible* the other pattern that seems to have been created in RSE will confirm itself in 5th Gen with the Grass starter.
