...I'm not sure if this should count for anything, and do pardom me if t's been said already, but that Klonoa pic was seemingly intended for him to be standing in that foreground, not the stage itself. Since he's obviously not standing on the stage (or the foreground, for that matter), then it can't be a gameplay pic. And I HIGHLY doubt that it's a cutscene.
And...Rayman being a trophy doesn't say much for a character from a totally different company. It's very likely this is just a very special case-I doubt we'll get many 3rd party main characters given a non-playable role.
(Though, could you imagine the possible outrage a Cloud Strife assist trophy would cause?)
