How long will I have to wait for the legendaries to come back?

Question

I accidentally killed Groudon during the main story. I beat the E4 and he was back. But he killed himself with Struggle. Same thing with Cobalion/Virizion. How long do I have to wait for them to "respawn"?

Answer 1

I believe you just have to beat the Elite Four and champion again, then come back. If not that, I know that with the legendaries of Nameless Cavern and Pathless Plain appear 12 hours after the last has been captured, and I'd assume it works the same way with defeats, though I haven't ever actually knocked one of them out before.

So try beating the E4 and champion first, and if that doesn't work, just wait twelve hours.

Answer 2

With groudon, I`m guessing beat the E4 another time. However, you will have to wait for Cobalion and Virizion to re-appear, unless beating the E4 will allow them to then re-appear. I recommend you just beat the E4 then go from there with groudon, then cobalion and verizion.
