Dark Seiza Blaster (ダークセイザブラスター Dāku Seiza Burasutā, lit. Dark Constellation Blaster) is a purple/dark color variant of Transformation Controller Seiza Blaster used by a brainwashed Naga Ray. It has full access on using Dark and Black Hole Kyutamas.

- "Dark Change!"
- ―Transformation standby announcement[src]
Like the original Seiza Blaster, a brainwashed Kyuranger inserts a Kyutama, making the Changer announce the name of the Kyutama, then pushes it forward, towards the nozzle; then they flip the grip down, but unlike the original they shout Dark Change (ダークチェンジ Dāku chenji) instead of Star Change, then pull the trigger of the blaster to transform.
- "Dark Attack!"
- ―Attack stand by announcement[src]
To attack, a brainwashed Kyuranger grips the Kyutama and pulls it backward like a joystick.
- "Dark Go!"

- "Dark Voyager!"
- ―Summoning announcement with Dark Kyutama[src]
To summon their Voyager, a brainwashed Kyuranger pushes their Kyutama to the left, then pulls the trigger.
The DX Dark Seiza Blaster includes a sound for a hypothetical Dark Voyager; this was not used by Hebitsukai Metal himself.

- ―Finisher stand by announcement[src]
To activate a finishing strike, a brainwashed Kyuranger grips the Kyutama and pulls it backward like a joystick two times like the original.
- "Dark Control!"
- ―Controller stand by announcement[src]
After summoning the brainwashed Kyuranger's respective Voyager, they then pull the black trigger to control the Voyager from the blaster by shifting the Kyutama in the required direction like in the original.
- The DX Dark Seiza Blaster notably recognizes the Ex-Aid Kyutama (エグゼイドキュータマ Eguzeido Kyūtama) alternatively as the Genm Kyutama (ゲンムキュータマ Genmu Kyūtama).
- It was essentially a recolored and slightly modified version of the core heroes' changers, like the Zyuoh Changer Final from the last season and the Giga Gaburivolver from Zyuden Sentai Kyoryuger.
