MS-06S Char's Zaku II is a mobile suit featured in the Mobile Suit Gundam: The Origin manga and its OVA adaptation. It was piloted by Char Aznable during the One Year War.

Char's MS-06S Zaku II is a customized version of the standard MS-06S Zaku II Commander Type (an overall improved MS-06F Zaku II) painted in his personal red colors. Being a commander's unit, a horn-like decoration was also attached to its head. Despite the high risks, Char personally ordered the removal of its limiters, allowing it to use its thrusters to the maximum limit. The hit-and-run tactics enabled by the resulting high thrust, and the impression its distinctive colors made on the battlefield, led to Char's nick name, "Red Comet". After the Clash of Loum, Vice Admiral Dozle secretly ordered Char to command the Falmer, a custom Musai-class battleship, and unit emblems and victory markings were applied to his MS-06S. These included bright white lines indicating it as the commander's unit, the unit number "A12" and emblems of the Falmer.
