Is there a Pokemon that gets smaller or gets a smaller name when it evolves?
Just for curousitys sake.
Venonat gets lighter when it evolves into Venomoth, and Porygon gets a bit smaller when it evolves into Porygon2.
As for the name thing...Yeah, not even gonna bother.
nincada to shedninja has a 10 pound difference, but shedninja is a ghost type and they tend to be lighter most of the time. or if you think that they are two different evolotuons, ninjask and shedninja then there's a 12 pound difference. there's actually a lot that do stuff like your asking if you were to look through the national pokedex here on the site you'd find a bunch of them.
