Do you get Landorus and co. from event?

Question

Landorus and co. = Landorus, Thundurus and Tornadus. I am a little jealous of my friend.

Answer 1

No

There were only one Event in Japan for Tornadus and Thunderus - Landorus hasn't been distributed as an Event yet.
You can get all 3 in ORAS, however, with a bit of trading.

Answer 2

As far as I can tell, landorus and company have not been given away as an event yet. If you want these three Pokemon, you can transfer them from your copy of black/white/b2/w2, or trade them from your Ω ruby/α sapphire.

Answer 3

As far as the internet can tell me, no

You can only get the 3o from black and white and black and white 2, I think 0.o
