Originally a Titan of the TV faction. Following a battle with the Juggernaut that left him nearly crippled, he returned to the TV faction base. While he was resting after dropping off a Juggernaut Cannon (a sample), the UFO Astro Toilet (Commander) reversed a teleportation flow to link with the TV base. The Duchess then appeared, seized Titan TV Man (Sentinel of Doom) with her four tentacles, and dragged him away. After stopping the teleportation, they used a parasitic core (Core Infiltrator) to turn him into the current Sentinel of Doom.

Faction: Astro Toilet Height: 50m Rank: Duchess Equipment: 4 Gravity Beam Arms.

Automated Energy Shield: A shield that activates automatically in emergencies.

Energy Chain Whip: Used to suppress targets or as a leash; can also neutralize opponents.

Anti-Gravity Device: Allows for fast flight to escape or pursue.

Emotional Control Device: A device that induces calmness when angry.

Abilities: Lasers: Fires lasers from the mouth and eyes. Powerful enough to melt most Toilets.

Executioner Speakerman: A replacement for Titan Speakerman. A Semi-Titan, roughly 3 times the size of a Large Speakerman.

Executioner Speakerman's Equipment: Death Scythe: A large scythe-shaped weapon emitting red light. It utilizes Astro Toilet technology to enter an anti-gravity state. Fitting its massive size, it can absorb energy over a wide area, and the blade can rotate to increase absorption range if necessary. It can be thrown like a boomerang in an anti-gravity state and possesses incredible cutting power; its sheer size allows it to kill a Striker Astro Toilet in a single blow. Furthermore, used energy can be recharged by absorbing any energy projectiles that hit the Executioner Speakerman. (Cross Mode): Can be driven into an executed enemy to absorb energy and deployed into a cross shape to serve as a beacon.

Anti-Gravity Device: Mounted behind the back like a halo. Unlike other Speakermen who use Speaker Boots for jumping, he is equipped with an anti-gravity device due to his size, alongside the Strider Speaker. Given that the Airship Speaker arrived via hyperspace jump and the Strider Speaker also flew, it is likely the Executioner Speakerman is capable of both.

Speakers

Auxiliary Speakers: Equipped with auxiliary speakers on the sides of the head like Titan Speakerman, and small speakers on the shoulders.

Repulsor Speakers: Speakers mounted on the palms. In the story, they are shown stopping and reflecting all incoming projectiles from the front.

Helmet: Wear a helmet that slightly covers the head woofers like Titan Speakerman, giving him a 'half-closed eyes' look. Unlike Titan Speakerman, he can intentionally move these like eyebrows.

Sonic Wave: Uses a single palm speaker to stop all energy projectiles from the Astro legion and reflect them back. His skill in manipulating sound waves surpasses what Titan Speakerman has shown, and his range appears to be the widest among all except for the later-appearing Titan Speakerman.

Energy Absorption: He appears to lack a core. To operate without one, he has an energy absorption function. Additionally, Supporter Speakers exist to provide energy even if it's not from an enemy. He can absorb energy through all parts of his body; this ability is also present in the Death Scythe, and energy absorbed by the body can be transferred to and discharged from the scythe.

Speakerwoman: Height: Roughly the size of a normal Speakerman. Rank: Elite Unit Equipment:

Cross Swords: Two cross-shaped swords emitting red light, equipped since Episode 78. They have incredible cutting power and are surprisingly light despite their heavy appearance, not hindering her mobility. It is unknown if the thin blades can function as propellers, but in Episode 78, she appeared to fly by rotating them.

Anti-Gravity Jetpack: Equipped since Episode 78, allowing her to glide at high speeds similar to TV Woman.

Speaker Boots: Speakers are attached to the soles, allowing her to leap even in mid-air.

Helmet: Worn on the head, giving her half-closed or angry-looking eyes like Titan Speakerman.

Shoulder Speakers: Speakers mounted on the shoulders.

Necklace: Wears a necklace with a small ornament shaped like Dark Speakerman's head. If it is indeed his head shape, it seems to be worn as a memento to remember him.

Belt Speaker: A small speaker is attached to the belt. It appears to be equipment similar to TV Woman's belt core.

Abilities: Sonic Wave: Same as a standard Speakerman.

Speaker Strider: Height: 20m Rank: Strider

Equipment:

Energy Cannons: Has two cannons similar to Titan Speakerman's arm cannons on mechanical arms and the lower body. Concentrated fire at close range is powerful enough to destroy a Destructor Astro Toilet's energy guns.

Drone Speakers: Equipped with detachable speakers similar to Titan TV Man's supporter TVs. Even excluding the main speaker, the sound waves emitted from these are powerful enough to burst a Destructor Astro Toilet's head with pressure instantly.

Mechanical Arms & Legs: Equipped with mechanical arms for energy cannons and auxiliary speakers, and the legs have been significantly reinforced.

Armor Plates: Attached to the mechanical arms, legs, and main body. Notably, the armor plates on the main body open like a mouth when using sound waves.
