Also the new Caterpilar pokemon will probably lose his secondary Grass typeing when it evolves, hopefully he will keep his ability's.
Or get better ones. It's not like Swarm and Chlorophyll are bad, but there can be better, especially if it changes what species of animal it's based on. Actually, I don't really know if it's this gen's Caterpie/Weedle/Wurmple; it seems like it might be more like a Spinarak/Ladyba/Kricketot.
