There are nineteen topics in the Suggest a New Move board; each corresponds to the element types that moves can relate to. Please post your idea as a reply to the appropriate topic.
When creating a new pokmon move, please provide the following information.

Name Please try to give it a name that makes sense and that isn't too similar to the name of an existing move (which includes the ones already approved by the Pokmon Factory.) There is a limit of twelve characters to a move name; this includes spaces and any other characters, such as the 2 in CONVERSION2 or the dash in MUD-SLAP.
Effect Be specific. The new moves page at the Pokmon Factory lists exact numbers for attack strength and for the chance of a side effect; if you do not provide this, then guesses will be made, and it is up to you to give enough detail so that a guess should be fairly accurate. For example, don't just say "really strong". HYPER BEAM and EXPLOSION are both "really strong", but one is almost twice as strong as the other.
