Pokemon's First Appearance: Pokemon Gold, Silver & Crystal

Although Entei (and the other legendary dog Pokemon) was an absolute pain in the ass to capture, it was totally worth it all when we finally caught it. With a 580 base stat total and perfect speed, power and stamina, Entei is in a league of its own. However, it lacks an assortment of moves and is weak against Ground, Rock and Water attacks. But it looks cool so that at least makes up for its lack of moves a little bit.
