Based on the Jegan, it was customized with high output cannons from various Gundam series and could attack with maximum firepower from all ranges. It has exceptional firepower, but requires more delicate energy management.
High Mega Cannon
Mounted in the head, this is the same high firepower beam cannon as found on the MSZ-010 ΖΖ Gundam's head. It can charged energy almost to the point of explosion, then releases it all at once. The Gunpla becomes inoperative after firing at full output.
Attached to the back of the waist, this two-barrelled cannon has extremely high power and can destroy a large number of enemies in a single beam shot. The panels on the sides of the cannon's barrels unfolds when in use. The concept for the Twin Satellite Cannon originated from the GX-9901-DX Gundam Double X, it can be used for various tactics such as battlefield suppression, sweep-ups, base defense and ambushes. Like the Gundam Double X's, the Jegan Blast Master's Twin Satellite Cannon uses the Satellite System, which allows it to be charged via the Super-microwaves sent from a transmitting facility on the moon. However in GBN's system, the Twin Satellite Cannon can also be operated by itself without the use of the Super-microwaves, but doing so requires a long charging time and a vast amount of energy.
Beam Sword/Beam Pistol
A pair of handheld weapons that can fire beams from their front muzzles or generate a beam blade from their top beam emitters. Stored on the back of the Twin Satellite Cannon when not in use.
Anti-ship Beam Cannon
Mounted in the side shoulder armor, they are revealed when the side shoulder armor flips up.
Mounted on the side hip armor, they pivot ninety degrees when in use. These are based on the beam rifle used by the G-Self.
Mounted on the front hip armor, these weapons can flip forwards and unfold for use. They are based off of the Gundam AGE-3 Fortress’ weapons.
Mounted under the feet of the Jegan Blast Master, the GN Cannons are based off of those used by the Seravee Gundam. Due to being hidden under the feet, they can be used for sudden sneak attacks. They also allow the Jegan Blast Master to hover.
Special Equipment & Features
Full Blast Mode
Based off of the special attack mode used by the Freedom and Strike Freedom, the Jegan Blast Master utilizes all of its armaments save for the Beam Pistol as a powerful blast attack. Unlike the normal Full Blast Mode, this one seems to use its attacks for a single devastating strike on an opponent. As the Jegan Blast Master does not charge up its Twin Satellite Cannons prior to using this mode, it is unknown how the Twin Satellite Cannon fires.Template:R
After his experience in the Mirror Mission, Yukio built the Jegan Blast Master so that he could improve his battle style further and be as strong as his friend, Riku Mikami. The Gunpla made its debut during the Force Battle that pitted the Force Build Divers and its allies against the superior numbers of the Coalition of Volunteers.
The Jegan Blast Master's color scheme is reminiscent of the RMS-108 Marasai's.
Although the Jegan Blast Master's Twin Satellite Cannon originated from the GX-9901-DX Gundam Double X, the design of the cannon's barrels are more similar to that of the GX-9900 Gundam X's Satellite Cannon. Two HGAW Gundam X Gunpla boxes are seen when Yukio is constructing the Jegan Blast master, thus it is likely the Twin Satellite Cannon was built using parts from those two models.
The HGBD 1/144 Jegan Blast Master comes with parts for a Jegan-type Beam Rifle and is considered to be part of its armaments. However, the Gunpla is not seen using this weapon in the anime proper.
