Sorry but as far as i know you can not be arceus on explorers of time.
Unfortunately you can get Arceus in Explorers of sky :/ The closest you get to seeing it is a statue...
no their wont
arceus isn't in Pokemon mystery dungeon 2. he is maybe in Pokemon mystery dungeon 3.
definetely the N,S,e,w dungeons. they have 99 floors. S,E,W all start you at lv. 1 N you can't get exp. points.Wrong, you forgot 1 destiny tower it has 99 floors and 1floor with arcues.
Either cheat or the mystery event
i don't think u can
Arcues is a event Pokemon but it is in the hall of orgin only obtainable by having a havens pipe.
