Excluding their Pokemon team (or their moves if your character is a Pokemon), what are weapons your characters have used/would like to use?
Hmmhmm. Ren and Kairn both have swords, and Ren also has a throwing knife. Latias and Latios will probably eventually get weapons, but their nature shall remain undisclosed. Other characters in the Chronicles have swords, spears, javelins, throwing knives, a serrated sword, sickles, claw blades, an arbalest, and the list goes on. XD
Mewtwo of course has the R-9WM, and will have a variation of the mech suit seen in the first pokémon movie as well as a motorcycle with spherical wheels (possibly).
If I ever do a trainer fic, someone somewhere will have a gun, and will probably critically injure or kill a major character's pokémon.
