King Servbot, known as King Kobun (キングコブン Kingu Kobun?) in Japan and renamed as Servbot Surprise in the English version of Marvel vs. Capcom 3, is one of Tron Bonne's most powerful attacks in the crossovers games she appears. In Marvel vs. Capcom 2: New Age of Heroes, eleven Servbots will combine to become the giant King Servbot. In Marvel vs. Capcom 3 and Project × Zone, a single Servbot will grow into the King Servbot. After the King Servbot appears, he will attack the target several times with a large hammer before returning to his normal size.
