Galvadon

Galvadon is the semi-mythical last living kaleidosaur specimen on all of Azeroth, hiding somewhere in Un'Goro Crater in the Journey to Un'Goro expansion for Hearthstone. Professor Doyle, who has embarked on an expedition to Un'Goro with his assistant Eddie, is convinced that the creature exists because every other expedition ever sent to find it has disappeared, which he says is obvious proof that it must be there. Galvadon is summoned when a paladin completes the quest "The Last Kaleidosaur".
