The XM-X1 Crossbone Gundam X-1 Kai ("Kai" is the Kanji "改", which translates to "Revision" or "Modified") appears in the Mobile Suit Crossbone Gundam manga.
Technology & Combat Characteristics
Following a fierce battle with the Jupiter Empire's Death Gale Squadron, the XM-X1 Crossbone Gundam X-1 was badly damaged. During its repair, the Crossbone Vanguard engineers took the opportunity to give the machine a slight upgrade as well. This change consists primarily of the addition of the screw whip, stored on the rear skirt armor. Designed to counter the reach advantage possessed by the EMS-VSX1 Quavarze and its snake hands, the screw whips are not as powerful as the snake hands but are still effective weapons. However, the scissor anchors of the original X-1 had to be removed as the storage space for their chains was needed to house the whips.

After returning to battle, Kincade Nau and Crossbone Gundam X-1 Kai were able to defeat the Death Gale Team. However, Kincade is forced into battle against the Earth Federation's mass-produced F91 Gundam F91 units, as well as being attacked by his former ally, Zabine Chareux. The heavily damaged X-1 Kai is overpowered by Zabine's XM-X2ex Crossbone Gundam X-2 Kai, and is sent hurtling into the Earth's atmosphere. Several days after the battle, Kincade and the X-1 Kai reappear just in time to help Tobia Arronax's XM-X3 Crossbone Gundam X-3 repel the Death Gale Team on Earth. After reuniting with the Crossbone Vanguard, Kincade goes on to destroy the massive Jupitris 9 and deal the deathblow to Crux Dogatie's EMA-10 Divinidad by using the screw whips to pierce the heavily armored cockpit. After the first Jupiter Conflict ends, Kincade entrusts the X-1 Kai with Tobia. A few years later, The X-1 Kai would be modified once again, into the "Skull Heart".
