I think its also possible that the kin part is derived from Kitsune. Drop the Tsu and e and you got kin. It also might be from Kinetic as in Kinetic energy.
Also I think after 5 gens of games, its safe to say that it's Pokedex number will be 004 for its regional dex spot. In all the games, the first fire starter has always been 004 in their regional dex. Yamitora1 (talk) 17:05, 8 January 2013 (UTC)
