Another month in the Pokemon 20th Anniversary celebration! From June 1-24, you can collect a lv.100 Manaphy through Wonder Trade > Get via Internet in Pokemon XY/ORAS!
Unlike other legendaries, which cannot breed at all, Manaphy can be put in the Pokemon Center and will produce a second rare Pokemon, Phione! (No, you cannot breed for more Manaphies…)
For more info, visit the official site!
