no it cant because regigigas could do all kinds of attack like electric,fire,water,ground,physic and more.plus regigigas is a legendary pokemon
so garchomp has no chance of winning.
No, Garchomp is too fast, and it can OHKO Sceptile after a Swords Dance.
yes
you need to beat the elite four and Cynthia has an level 54 garchomp.
Then you have to beat Darkrai.
yes because mew two only knows physic,but on the other hand regigigas knows more attacks like physic,electric,water,fire,fighting,rock.
Probobly scince i beat them with a level 63 Empoleon
regigigas is in there you have to beat the Pokemon legeau
If it was me, I would use garchomp, floatzel and electabuzz. The best possible team is garchomp, a starter and metagross
beat Darkrai in DARK CRATOR and then Cresselia will join you.
you have to beat the Pokemon league and go to snowpoint city then go to the tower
No, but if you want the regis (apart from regigigas as it is not in the game) and mew you will have to.
Use an ice type Pokemon
