Is Game Freak trying to make Kyogre even weaker? First, Groudon got an ability that makes him immune to Water-type moves. His signature move, Precipice Blades, has a base power of 120 with an accuracy of 85. Kyogre gets Origin Pulse, which has a base power of 110 with an accuracy of 85 as well. I don't get why Origin Pulse has to be weaker than Precipice Blades. Is there an additional affect that Origin Pulse has?
As you know the rain boost water type moves and Origin pulse is water type move and preciplce blade does not get boost from sun because it is a ground type move. So origin pulse in rain will be stronger then precipice blade in sun.
Same goes for their primal abilities.
So basically it is not an error.
