Diego (Ice Age)

"Diego" is the tritagonist of the Ice Age franchise. He used to be part of Soto's pack before he reformed and joined Manny's herd.

Why He's Up For Round Two

 * 1) He is very mature and usually serious, unlike the rest of the herd.
 * 2) Despite starting off as an antagonist earlier, he was very thankful for Manny saving his life from falling into lava on the first film. Because of that, he has a change of heart and grows to respect Manny.
 * 3) When Soto tries to attack Manny near the end of the first film, Diego sacrifices himself by getting injured by Soto in order to save Manny's life.
 * 4) He is also one of the most intelligent members out of all the herd.
 * 5) Despite being the more serious members of the herd, he can have a fun loving personality every now and then.
 * 6) Denis Leary did a great job voicing him. Skyler Stone was also decent and makes good impression of Leary in The Ice Age Adventures of Buck Wild.
 * 7) His design is very cool for a Saber-Toothed Tiger.
 * 8) His chemistry with Manny and Sid is awesome and believable.
 * 9) He can give us funny moments such as "Move sloth!", "Who's up for Round Two?" and the "Where's the baby?" bit.
 * 10) Unlike his two best friends, he wasn't flanderized in the fourth film, "Continental Drift" and still had his original personality.

Bad Qualities

 * 1) He started off as a bad guy working for his pack in order to eat the baby on the first film, before he redeemed himself.
 * 2) He can be temperamental at times.
 * 3) Despite not being flanderized in "Continental Drift", he was heavily sidelined in Collision Course and barely did anything to move the plot forward.

Trivia

 * His famous quote from the first film, "Who's up for Round Two?" became an Internet meme.
