Actually, I liked what happened with Feraligatr's name! Back then, I didn't realize it could've been primarily due to character limitations, so I thought the new take on the spelling of "gator" was a bit interesting. Plus, it was the only Pokemon name I knew where a vowel was just chopped off in the middle of a noun like that. Feraligator, if able to fit, would be OK yet a bit weird, IMO.
But yeah, Desukan's English name should match his creepy abilities and vibe, being just as awesome as his Japanese name!
