So I was playing a Random battle on Showdown when the opponent's Lickilicky used Explosion. EXPLOSION. It doesn't make any sense! To me at least. I looked at Lickilicky's page on here and Bulbapedia and they both say it learns Explosion by TM. I'd like to know why, at least a theory cos it's probably just dumb Game Freak logic like Slowbro getting Flamethrower.
Complete and utter gamefreak logic. Fun fact: LickyLicky is one of three Pokemon that gets a STAB boost from explosion.
