Topic is the title. I'm in a pretty big argument with friends at GameFAQ about if a Lucario could take on Ike from Fire Emblem, and then Role Play was brought up, the idea being that Lucario could use it to copy all of Ike's abilities.

However, others are arguing that it can only copy one ability because a Pokemon can only have one in the main games. I brought up PMD because of Pokemon having multiple abilities in those games, but I haven't actually found any evidence of exactly how Role Play works in regards to multiple abilities.

So, does anyone know how Role Play effects double ability Pokemon in Mystery Dungeon?
