Mister Bushido (ミスター・ブシドー) is an alias for Graham Aker (グラハム・エーカー), an ace pilot who is obsessed with defeating Setsuna's Gundam. After a fierce duel with Setsuna in space, Graham's face is scarred from the explosion of his Mobile Suit, and his pride as a pilot and leader is greatly wounded. To make amends to the comrades he lost due to Setsuna's piloting, Graham feels he should seek a glorious end in battle with Gundam. While he has the unquestionable authority to launch at any time, Graham won't budge an inch unless he knows Gundam is there.
