give it to hold plate
There is no Unknown Plate for Arceus, there are only plates for each type.
no you must have plates ex: thunder plate or sky plate
arceus with fire plate for aaron arceus with grass plate for bertha arceus with water plate for flint arceus with grass for the champ improvise for lucian
Arceus can be any element as long as you have the plate of it, for example, if you gave Arceus the rock plate, he will turn into a rock-type. I hope this helped you.
Arceus is a just a Normal type until a plate is given for it to hold
It can change type with plate like spooky plate turns arceus into a ghost type and fist plate into fighting with all the plate it can turn to all type
Give it an ancient plate to hold, you will find a number of these on you adventure. (e.g, a meadow plate makes arceus the grass type. Lets say you swapped items with Draco plate. Arceus is now a dragon type. )
Arceus Is Normal type...But Its Multi-type Ability Makes It Become The Type Of The Plate... That It If You Give Arceus Flame Plate..It Will Become Fire Type And Give Him Draco Plate It Will Become Dragon Type...And So On
An earth plate is a plate you equip to arceus to make its ground type moves.
i would say Draco PLate because that way he can learn Draco meteor (if ARCEUS loves you enough)
You get a arceus with cheats or you go to a Nintendo event- Then you give the arceus a plate (example- splash plate) and make it hold it. Take it away to make it normal color again. Hope that answers your question. =)
You can find each plate somewhere in every game since Arceus' release. If you sold it, then just use normal Arceus. 1 weakness isn't too bad.
