Feraligatr is the final evolution of Totodile from the 2nd generation of pokemon. He was my strongest pokemon in both Silver and HeartGold. Despite looking a little funky and bulky, I really liked him. Not as much as say Blastoise, but still pretty cool.
Feraligatr's Japanese name is オーダイル (Odairu) which is probably a combination of 王(O) which means "king" and the English word "crocodile".
