Todaka was a high-ranking officer of the Orb Union military who appears in the anime series and Mobile Suit Gundam SEED Destiny. He was one of his country's able and tractable battlefield commanders and always carried out the orders given to him, even if he disagrees with them. Though he may appear single-mindedly obedient in the series, he is not without any opposing views against Orb's leadership that consolidated itself by joining the Earth Alliance especially under its self-serving representative, Yuna Roma Seiran.
While not actually seen in SEED, Todaka appears in a flashback where he was involved in the civilian evacuation of Onogoro Island during the Alliance invasion in C.E. 71. He finds a grief-stricken Shinn Asuka, whose family was accidentally killed in the evacuation due to the intense battle taking place around the island, personally taking him aboard one of the ships and comforting him.
Gundam SEED Destiny
He officially appears in SEED Destiny as a captain who unwillingly orders a shot to be fired at the bow of the LHM-BB01 Minerva as a warning effectively blocking its seeking sanctuary back in Orb territory. It was also at this time that the Orb Union allied itself with the Earth Alliance to the distaste of many members of its fighting force. He next appears as the captain who deliberately lets the Archangel get away with the supposed 'kidnapping' of Cagalli Yula Athha from her wedding to Yuna Seiran. As a show of support in terms of resources and manpower, Todaka is part of the unit sent to aid the Earth Alliance forces to hunt down and destroy the Minerva. He is next seen aboard the Orb flagship Takemikazuchi and is the commander of an Orb flotilla serving as reinforcements to Neo Roanoke's forces. In this battle he has had several of his counsel ignored, orders vetoed and manpower senselessly sacrificed by Yuna Seiran who has accompanied aboard as Orb's official liaison to the Earth Alliance in this mission operation during the Battle of Crete. During the battle, Shinn Asuka enters SEED mode and begins destroying the Orb fleet, unknowingly killing Todaka in the process. Before his death, Todaka ensures the safety of Yuna and his men. He also orders his second-in-command, Armagi, along with many of the survivors, to join Cagalli's cause aboard the Archangel rather than return and be forced back into battles at the whim of the Earth Alliance.
