21 - Ripto (Spyro 2: Ripto's Rage)
I found Ripto to be quite an interesting antagonist. Despite his rather puny size, he still manages to give off the aura of a tough guy. As he continually takes over worlds in Avalar, you have to continually kick him out. And after beating his two goons, Crush and Gulp, you get to take him on for yourself. And then...spoiler alert here...Ripto finds himself burned alive in a lake of lava. But wait! Somehow he returns without a scratch in Enter the Dragonfly! I suspect he utilized the dark magic that is poor game development in order to do so.
My favorite cutscene from Spyro 2

20 - Cortez (Timesplitters: Future Perfect)
While Cortex was the main hero of all three Timesplitters games, it wasn't until the third game that the main story mode was really developed well, and thus it wasn't until then that we got to really see Cortez in action. Cool, collected, and a master of disguise, Cortez was the only person capable of transcending time and space to save the world. The voice actor fit the part perfectly, and most of the lines he delivered were actually able to cause laughter from the player, so you know that they're decent enough.

19 - Captain MacMillan (Call of Duty 4: Modern Warfare)
Although MacMillan only appeared in one mission, it was his mere prescence that made the mission so memorable, and also the best in the entire game. You'll find that in the mission "All Ghillied Up", Captain MacMillan is your commander and guide as you sneak past enemy troops and attempt a daring assassination of a known terrorist. His soothing Scottish accent will calm your nerves as you crawl in the grass, three feet away from an enemy tank that's nearly about to crush your head as it slowly tumbles by. And even though by the end of the mission you have to carry MacMillan up to the helicopter yourself, you never get mad at the guy.
