Honestly, it all depends on how you level them up.
your wrong arceus is the best and strongest pokemon
Not really, because Arceus can't learn all the TMs like Mew can. And anyway, you can kill a level 100 Arceus with a level 1 Rattata/Pidgey/Starly. But if you're comparing it to Magikarp or Unown or something like that then yeah, you're right.
Ho-oh or Lugia is the strongest Pokemon in Crystal. Tyranitar would be third strongest.
There is no actual "strongest Pokemon", but if I had to decide it would be Arceus and Mew.
If by "strongest" you ment strongest Pokemon that would probably be Palkia if you ask me.well if you ask me i think it would be arceus which you can get in action replay.
The strongest electric type would be Zapdos.
That would be Rayquaza.
The strongest pokemon would have to be a rattatata or starly holding a focus sash that knows endevor and quick attack.
mew is the strongest Pokemon
yes it is the strongest Pokemon
The strongest Pokemon is Lugia. It's the strongest, the rarest is Celebi.
