Weird Stuff That's Happened to Me

My Legendary Pokemon

So... this is the final stretch in order to become the Champion.  I'm almost done with the game.  I'm also gonna win it with Kyogre, the water type legendary, and I named it Splasher.  I had it in it's primal form.  So, Splasher knows this move called Origin Pulse, which is a water type move.  I was going up against the first of the Elite Four, who's a dark type trainer.  I had Splasher use Origin Pulse.  Now understand this; Splasher was level 49, and the Mighteana that I was up against was level 50.  Origin Pulse took out the Mighteana out with ONE HIT.  Let THAT sink in.

Do you guys think that Origin Pulse is a little OP?  Because I sure do!  And I love it!  Kyogre is AWESOME!  So, do you guys think that Kyogre is OP JUST because of that move or not?  Tell me in the comments below.  PEACE!
