Following the conclusion of the Jovian War in UC 0133, the XM-X1 Crossbone Gundam X-1 Kai was further remodeled by the Crossbone Vanguard remnants. Because SNRI used the basic Crossbone Gundam frame to produce their next generation mobile suit, the F99 Record Breaker, new parts were in abundant supply. A balance was struck between the original X-1 and the X-1 Kai, mounting one scissor anchor on the front right skirt and one screw whip on the rear left skirt. However, the most eye-catching change was the skull relief on the chest, which was seen as a better symbol for a group of space pirates than the crest of an elite force centered around the concept of nobility. This distinctive decoration earned it the nickname Skull Heart thanks to rumors and vague sightings from the space colonies. In a battle with the Amakusa, the Skull Heart wielded a newly developed special weapon, the peacock smasher. This crossbow-like weapon mounted nine separate beam guns which could be fired in any arrangement, but simultaneous use drained its energy and required the replacement of the barrel parts. During the attack on SNRI’s lunar facility, the Skull Heart was badly damaged by the new Jovian mobile suit Cornigs, forcing the Crossbone Vanguard to hastily repair it with whatever parts were available, producing the XM-X1 Crossbone Gundam X-1 Patchwork.
