MG Ex-S Gundam/S Gundam Sentinel


The S Gundam is a powerful transformable Mobile Suit operated by the Earth Federation during the events of Gundam Sentinel, one of Hajime Katoki’s earliest and most notable Gundam works. The S Gundam is a derivative of the ZZ Gundam, featuring a similar Core Block System that separates the Mobile Suit into two massive attack fighters called the G-Attacker and G-Bomber, and a smaller G-Core Fighter. The S Gundam also features a highly experimental self-learning AI named ALICE, which could control the entire Mobile Suit in dire circumstances, but more commonly controls the G-Attacker and G-Bomber while the pilot controls the G-Core. The S Gundam would receive a significant upgrade aboard the Pegasus III carrier, becoming the Ex-S Gundam. The Ex-S Gundam features additional armor plating and thrusters, which, combined with the ever-improving ALICE System, made this Mobile Suit a dangerous threat for the New Desides.

Included alongside the MG Ex-S Gundam/ S Gundam for accessories:

  • Beam Smart Gun
  • Radome for Beam Smart Gun
  • Beam Saber x2
  • INCOM Adapter x3
  • INCOM Bend x4
  • Display Stand


The MG Ex-S Gundam/ S Gundam borrows parts of its construction from the original Master Grade versions of both Mobile Suits released in 2003 and 2002, with a handful of pieces from the MG PLAN303E Deep Striker, combining almost 20 years of Master Grade engineering! This model kit includes the parts required to create either the Ex-S Gundam or the S Gundam, and not both. Either Mobile Suit will retain full functionality of the Core Block System, allowing builders to disassemble the Mobile Suit into its larger sections for individual display! The MG Ex-S Gundam/ S Gundam is the most recent and likely the last of Bandai’s Master Grade Gundam models to utilize screws in its assembly, helping to stabilize the Mobile Suit’s large and heavy limbs.

Weapons and Other Notable Attributes 

The Ex-S Gundam includes two Beam Sabers stored inside its knee armor for close-quarters combat. In the S Gundam configuration, builders can attach the Beam Smart Gun to the Mobile Suit’s back when not in use. In the EX-S configuration, the Beam Smart Gun attaches to the front skirt for storage. Bandai included a set of PVC wires to display the Ex-S Gundam’s INCOM units in an active state.

By implementing the technique of Top Coating, you can do a great deal to help preserve the longevity of your models. This process will protect the original plastic of your model kit and prepare it for any additional modeling techniques to follow.

You can drastically improve your results by making the details pop on the Ex-S Gundam/S Gundam Sentinel with Panel Lining. The simplest solution for this is Gundam Markers or Tamiya Panel Line Fluid. Making your own panel wash is always a great option too! It is always recommended to Topcoat with clear gloss beforehand, as some of the products commonly used for Panel Lining will degrade the untreated plastics over time.

Another way to keep adding detail is by applying Stickers/Marking DecalsTop Coating before application will help decals stick to the surface much better. Using Top Coat after application will help hide the seams on traditional sticker decals as well as waterslides. This additional step will also keep them from peeling over time. Using Decals is a great way to add an even greater level of detail to your scale models.
