Character: Quattro Vageena

Known as the "Red Comet" for his high-speed attack tactics, Char is the most famous of Zeon's ace mobile suit pilots. He earned his nickname by destroying five Federation battleships during the Battle of Loum, and after the attack on Side 7, he becomes the dreaded nemesis of the White Base crew. However, defeating the Federation isn't the only thing on Char's mind, and his distinctive mask hides the face of a young man bent on his own personal quest for revenge. As the story continues, Char begins putting his own complicated schemes into motion, even as he becomes distracted by his growing rivalry with the Gundam's pilot.

The legendary "Red Comet" has now reappeared as the leader of his own Neo Zeon movement. During the One Year War, Char fought for the Principality of Zeon as an ace mobile suit pilot. He then helped found the AEUG resistance group, which opposed the tyranny of the Federation's Titans faction - a role which put Char briefly on the same side as his former adversaries Amuro Ray and Bright Noa. However, Char's new goal is to complete the work of his father Zeon Zum Deikun by forcing all of humanity to emigrate to space, and he once again faces Amuro as an adversary. Amongst themselves, Neo Zeon's officers suspect that Char's true purpose is simply to avenge himself upon Amuro, and that their glorious cause is merely an afterthought.

The world's biggest fan of red, horns, and things that are three times moreso than other things. People call him the "Red Comet". A red uniform and a concealing mask are his sartorial trademarks. (At least when he's not stark naked.)
