How to get cobalion terrakion and virizion?

Answer 1

Yes, you can trade Cobalion in order to acquire a Virizion however it is not necessary to trade Cobalion in order to acquire Virizion because Virizion is available for capture in Pokémon Black as well as Pokémon White after Cobalion has been caught or defeated in the Mistralton Cave.

Answer 2

To catch the three legends you go to a cave near driftveil city. You need a Pokemon that knows flash and strength. Next go to victory road near the end you see a small boulder you need cobalt on to move it( which is above) you go in if you have him then battle terrakion. In order to get virizion you need to have the first two go in pinwheel forest then when you see a small opening go in then go west then north then you see a cave go in and there is virizion.

Answer 3

You will first need to have three Pokémon that have maximum effort values in your party and then you will be able to soar and you will be able to see a Mirage Island called Pathless Plain that you will be able to land on, Pathless Plain's location is near Pacifidlog Town. On the island you will come across a portal and interacting with it will cause Cobalion, Terrakion or Cobalion to appear depending on the day of the week it is. Cobalion will come out on Sundays, Wednesdays and Fridays. Virizion will come out on Mondays and Thursdays and Terrakion will come out on Tuesdays and Saturdays.
