shadow articuno

after a fight with shadow lugia, articuno was ko'd and also corrupted by cipher. but its mind remained in tact partually. also it can talk now! it can become evil if angered. it has the look and power of a shadow pokemon. you sneak into cipher's lab and sacve it. its immune to pokeball (even masterball) capture but it becomes your friend. you two are then sent into an au after you two follow a portal(you choose which au it leads to)
