Lion

Lions are seen in Crash Bandicoot 3: Warped, where they are enemies in Tiny Tiger's boss fight. Whenever Tiny gets hit, he will jump up back to the top of the coliseum, and start roaring. Lions then come out of the doors in the coliseum, and try to eat Crash. They come out of random doors, regardless of where Crash is standing. Lions aren't seen in any other games. Crash can defeat them by jumping on them or spinning them or Fruit Bazooka. He can also avoid them by standing at the very edge of the left side of the coliseum. He may have to jump, though, if he isn't at the right position because if he doesn't have to spin them then the lions disappeared before Tiny could jump to Crash.

Trivia

 * The lion's faces look just like Tiny's, only yellow.
