Rayquaza's signature move is Dragon ascent
Xerneas's is Geomancy
Yvetal's is oblivian wing
then what is the signature move of Groudon and Kyogre. Do Groudon and Kyogre signature movesstay the same even when they reveal their Primal forms
NOTE:: before you answer check that the move can ONLY be used By Groudon and Kyogre only.
thank you in advance
