it is regigigas
to get it, you need to have seen all 266 Pokemon, but 1 will be missing so go to the union. there, you will learn stuff about a vortex in hippowdon temple. go catch regice regirock and registeel then go to hippowdon temple and once you see the vortex, go in. place the Pokemon on the pedestals and go in the room. be careful, because wherever regigigas steps, it causes and does damage then once you caught it be happy as you have finished the game.
Hope this helps
