Bandai SD BB Senshi RX-105 Xi Gundam
Bandai SD BB Senshi RX-105 Xi Gundam. Hathaway's mobile suit, super-deformed.
The Xi Gundam in pocket form. The RX-105 Xi Gundam is Hathaway Noa's mobile suit from Mobile Suit Gundam: Hathaway's Flash, a heavy Universal Century machine built around a minovsky craft system and funnel missiles. This BB Senshi kit (No.386) shrinks it into a chunky, super-deformed build that snaps together in an afternoon and still carries the suit's bulk and presence.
Build difficulty
Beginner-friendly. BB Senshi is a snap-fit SD line moulded in colour, so there is no glue, no paint, and no nipper skill needed to get an accurate result. A pair of nippers tidies the parts as they come off the runner, but the kit is forgiving for a first build.
Technical highlights
For an SD kit, the Xi packs in real gimmicks. The shoulder and chest armour open and close, the head swivels on a double-sided ball joint, and the waist rotates a full 360 degrees, so you get more posing range than the stubby proportions suggest. A display stand is included to hold it up.
What makes this kit special
-
Opening armour: the shoulders and chest open and close, a neat touch rarely seen at SD scale.
-
Moulded-in colour, snap-fit: accurate straight off the runner, no paint required.
-
Posable for an SD: double-jointed head and full waist rotation.
-
Display stand included: the Xi stands proud without needing a separate base.

What to watch for
SD kits use stickers for some of the finer markings, so take your time seating them straight. The Xi is a stocky design and sits well on its own feet, but the included stand helps if you want a leaning or hovering pose. As with most SD kits, the smaller parts are easy to lose on a busy desk, so work over a tray.
Build notes
Nothing here needs glue or paint. If you want to sharpen the look, a dark Gundam Marker run into the armour seams adds depth in a few minutes.
