Pokémon Trainers travelling the Unova region in Pokémon Black 2 & White 2 can now capture the legendary Pokémon Deoxys by connecting to the Nintendo Wi-Fi Mystery Gift service.
Deoxys comes at level 100 (If only you could go back in time and tell your younger self it does get better!) and knows Psycho Boost, Recover, Nasty Plot, and Dark Pulse, the later two of which it can not normally learn! In addition to this the Pokémon comes in a Dusk Ball, has the Pressure ability and also holds a Life Orb which boosts attack power at the sacrifice of a little HP whenever the Pokémon holding it does damage to its opponent.
To capture your own Deoxys simply go onto the Mystery Gift option from the main menu and select “Receive from Nintendo WFC”. Simples.
