Pretty much any Fighting-type Pokemon, as Arceus is a Normal-type Pokemon.

Arceus did not evolve from any Pokémon.
Arceus is not in any Pokemon game legally. You can only obtain it by certain events.
Arceus & Mewtwo both are strong than any pokemon.

Arceus cannot be caught legitimately in ANY pokemon game.
It Depends On What Pokemon You Have NOT the game. (unless you count the Pokemon that is in there and the Pokemon that is not...) Easy Mode: Defeat Mysterial with a LV 100 Pokemon That uses Hyper Beam. (Arceus Makes it much easier cause I defeat Mysterial without any turns in 2 minutes! But you can use other Pokemon too.) Normal Mode: Defeat Mysterial With other Ledgenary Pokemon. Hard Mode: Defeat Mysterial With Your Normal Pass.
yes because arceus can be any type of pokemon
No. In fact, Mew is the strongest Pokemon because it can learn any move that can easily take down any Pokemon in 3 or less hits. As for Arceus, it is the 2nd strongest.
