SE Dark doors

Is it possible to see which charcters dark copies you have beaten already? I know where all the characters are but im not sure which characters i have already beaten, and i dont want to go all the way over to the door only to find it not being there.

Yes it is. There's a room that has all tha characters trophies in it an' as you pick each one off each time ya go back more an' more trophies disappear. Tha door ta that room is in tha swamp area with tha leaves with wind blowin' on 'em (this area also has DK music). It's also tha small room in tha middle of tha map in tha center an' its marked by a large blue/pinkish arrow pointin' towards it. Once ya beat all tha characters there's like an invisible pathway that appears (just go throughout tha room pressin' up if ya can't find it) that leads to tha battle with Tabuu.

Also, a bowser head (Not the detailed one. One like you would see on Mario Party circle.) should probably be on the dot that you have not been to.

yeah, i checked my map on the wii and there werent any heads, but i did one more battle and there they were. They must only show up after a certain amount of fighters were beat. Thanks for the help. i finally unlocked Sonic!
