Diego (Ice Age)

Diego is a saber-toothed tiger from the Ice Age franchise who used to be part of Soto's pack before he reformed and joined Manny's herd, he is voiced by Denis Leary.

Why He Rocks

 * 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 and has a change of heart and had respect for 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.
 * 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!" and the "Where's the Baby?" bit.
 * 10) He gave us the "Who's Up for Round Two?" meme from the first film.
 * 11) Unlike his two best friends, he wasn't flanderized in the fourth film and remained a likable character (even though he was heavily sidelined in the fifth film and barely do anything to move the plot forwards).

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) He was heavily  sidelined in the fifth film and barely do anything to move the plot forwards (although he remained a likable character in the fourth film since unlike Manny, Sid, Crash and Eddie, he wasn't flanderized).
