Super Deformed [SD]

Super Deformed (SD) Gundam takes the same mobile suits from the main series and shrinks them into cute, big-headed chibi figures, a style that started as a 1985 fan illustration and grew into its own standalone Gunpla line. Rivals Corner's collection spans entry-level BB Senshi kits, SD Cross Silhouette figures with swappable proportions, and the premium MGSD (Master Grade SD) range for serious collectors. Free tracked UK shipping applies on orders over £99.

Cute on the Outside, Serious Engineering Inside

SD Gundam started life in 1985 as a fan illustration in a Japanese model magazine, and Bandai turned it into a standalone line two years later with SD Gundam BB Senshi. Rivals Corner's collection carries that history forward: entry-level BB Senshi kits, SD Cross Silhouette figures built for adjustable proportions, and MGSD, the premium Master Grade SD line, all under one roof. This isn't a joke spin-off. It's a genuine parallel product line with its own devoted following.

Build a basic BB Senshi kit and you're looking at a handful of parts, snap it together in an evening, no tools beyond your fingers required half the time. Step up to MGSD and the part count jumps dramatically, full inner frame engineering shrunk down into the chibi proportions rather than stripped out. Miss a frame step on an MGSD kit and the compact scale makes it harder to fix than on a standard Master Grade build. Get it right and you've got genuine engineering wearing a deliberately silly outline.

Which kit's worth grabbing first? MGSD Gundam Aerial brings the Witch from Mercury's lead mobile suit into the premium SD format, one of the strongest sellers in this entire collection based on review volume alone. MGSD Destiny Gundam covers the SEED Destiny side of the range at the same premium tier. Legend BB FA Knight Gundam is genuinely SD-exclusive, a character with no standard-scale equivalent anywhere else in Gunpla. Reddit's r/Gundam has entire threads debating whether Knight Gundam even counts as canon, so you're picking up a piece of ongoing fan discussion, not just a kit.

New to Gunpla entirely? High Grade [HG] is the standard-scale starting point most builders begin with. Chasing the full-detail Master Grade experience instead? Master Grade [MG] covers the non-chibi version of the same engineering.

Frequently Asked Questions

What does SD mean in Gundam?

SD stands for "Super Deformed" (sometimes "Superior Defender"), a style that reimagines Gundam's mobile suits as cute, big-headed, stocky chibi figures. It started as a 1985 fan illustration and grew into its own standalone media franchise, with model kits, anime, and video games all under the SD banner.

What's the difference between SD and regular Gundam kits?

Standard grades (HG, RG, MG, PG) aim for realistic proportions and increasing detail. SD deliberately goes the other way, with exaggerated proportions built for a fun, customisation-friendly build rather than screen accuracy. SD Cross Silhouette kits specifically let you adjust body proportions after building, something no standard-scale grade offers.

What is MGSD?

MGSD stands for Master Grade Super Deformed, a premium SD line that applies Master Grade-style inner frame engineering to the chibi proportions. It sits above entry-level BB Senshi and mid-tier SD Cross Silhouette kits, both in detail and in price.

Is SD Gundam a good starting point for beginners?

Yes, particularly the entry-level BB Senshi kits, which use simple part counts and straightforward assembly. It's a genuinely different experience from working up through HG, RG and MG, some builders start with SD purely for the fun factor rather than as a stepping stone to bigger kits.

Who is Knight Gundam?

A knight-themed character exclusive to the SD Gundam universe, with no equivalent in any standard-scale Gundam series. He's part of SD Gundam's long-running fantasy spin-off tradition, alongside samurai-themed Musha Gundam designs, placing familiar mobile suits into settings the main Gundam continuity never touches.
