Well, I remember naming my Swellow "Hybird" as a six-year old. But that was then. Before I knew about Base Stats.
Recently, it's been pretty much this:
Ayato the Metagross
Rembrandt the Gallade
Kenage the Salamence
Ononoko the Haxorus
Rekka the Chandelure
Odaya the Tyranitar
Kanoshi the Empoleon
I'm Japanese, so I gave you the Romaji.
I name my Gallades "Rembrandt" because it just seems so fitting.
You just made my day, Da_Man32.
