Primal Groudon Revive?

Question

I accidentally made primal Groudon faint when I was trying to make him into low health. Will he respawn if I return to the cave of origin.

Answer 1

If you beat the Elite 4 and Champion again it will resapawn and it will be available to catch though you will have to take a different route in the cave of origin to get to it. Once you come into cave of origin go into the cave on your left on the top level and follow it down to the bottom.
