Optional equipment that can be mounted onto the Gundam Dantalion's back. The 'T' in its name stands for 'Top'. The T Booster allows the suit to make wide-ranging solo flight, conduct base assaults and to provide relief to stranded allies, playing a major role during the Calamity War. In combat, the T Booster’s high mobility enable the suit to baffle the opponent with hit and run style attacks. The T Booster can transform into a set of close combat use heavy armor for both offense and defense. The armor covers the Gundam Dantalion’s shoulders and arms, and grants it the use of the Gigantic Arms. This configuration, known as Half Cowl T, exemplifies the Dantalion’s design philosophy, and makes it possible for a single machine to attack and defend bases.
