Emonga - based on the Japanese scientific name for flying squirrel, モモンガ (Momonga)
Keromatsu (Froakie) - ケロ (kero) is the noise a frog makes in Japanese, and 沫 (matsu) meaning foam/ bubble.
Harimaron (Chespin) - 蝟 (harinezumi) meaning hedgehog, 針 (hari) meaning needle (like the little tufts on Harimaron's head), and marron, which is French for chestnut, hence the English name Chespin (Chestnut/pin).
Fokko (Fennekin) - 狐 (ko) meaning fox, fuoco (Italian; fire) and 子 (ko) meaning child. Fennekin is obviously based on the fennec fox.
Kojondo (Mienshao) - "shao" as in Shaolin, and Kojondo being a mix between Taekwondo and Kokondo.
Zorua - Zorro is Spanish for fox, and rua is Irish for red.
Mijumaru (Oshawott) - 未熟 (mijuku) meaning inexperienced/ not yet matured, and 丸 (maru), which is common ending/ character in names.
Futachimaru (Dewott) - 二つ (futatsu) meaning two, 太刀 (tachi) meaning long sword and 丸 (maru), a leftover from Mijumaru
Daikenki (Samurott) - 大剣鬼 (Daikenki), lit. large sword demon. Daikenki is the Chinese reading for these three characters. Samurott is obvious. (Samurai + Otter?)
Thought I'd post some that weren't up.
To be honest, most Pokemon names pertain to something that defines their characteristics/ design, you just need to look closely.
