The Visaka-class is a virtual lifeform created by the Anti-Spiral, and the most powerful entity in the Anti-Spirals armada (outside the Anti-Spiral themselves), far more powerful than the Ashtanga. It only appears in the novels and the script, so no images exist of it unfortunately. It takes the form of a great black dragon, comparable in size to the fake Nia (making it at least the size of a planet).
The Visaka-class wasn't detected by the Spiral Radars as unlike the Ashtanga it wasn't hiding in multi-dimensional space, but instead willed into existence by the Anti-Spiral, who control life and death.
Like the Ashtanga, it can manipulate probability and perform random Schrodinger Warps."It wasn't hidden, it was born," says LordGenome head. "The Anti-Spiral is the universe itself. It controls all death and birth. The isolated universe must have said that."
Super Galaxy Gurren Lagann unleashes Mega-Maelstrom Vortex Cannon bombardment across the space-time continuum which spreads across the universe. The Visaka is wounded, but it survives and attacks Super Galaxy Gurren Lagann via performing a short warp through Super Galaxy Gurren Lagann's Super Spiral Field and directly attacking Super Galaxy Gurren Lagann.The enemies attack was a hit even though it should have been completely defended by the Super Spiral Field.
"What do you mean?" Asked Yoko.
"I don't know. The Spiral Field is alive and well on the instrument."
Tetsukan checked the monitor and said.
However, the attack does not stop.
"But it's hitting."
Gimmy said while balancing the swaying aircraft.
"It's a probability negating bullet. The enemy is negating the odds that we defend."
Gurren Lagann novelization - Volume 4 said:It's a simultaneous strafing to a parallel space-time continuum. How charming is it? This machine thinks so and is fascinated.
The Visaka-class devours Spiral Energy, draining its target of power. It then returns the Spiral Power as a powerful shockwave, preventing the pilots from synchronizing with the spiral galaxies and depriving them of Spiral Power.In the wake of Simon's words, the guns of the whole body blew fire. The fires disappeared into empty space. After a moment when silence wrapped the universe again, a big explosion spread throughout the universe. The enemy reaction that the shards of the Vasuki class materialized dissapeared.
When there was a relief atmosphere in the second cockpit, the aircraft suddenly showed a big dragon's face on the monitor, and at the same time an alert sounded.
The Vasuki class wrapped around the body of Super Galaxy Gurren Lagann.
"Where did this guy come from?"
LordGenome's head answered the question of Dayakka.
"It's a short warp. It passed through the super spiral field and approached directly. It's a demonstration battle. All the other aircraft were individual."
(It's a spiral-eating dragon I'll seal you, your spiral power.)
The voice of the Anti-Spiral echoed.
Severe pain ran into Simon's body.
The stronger the rotational force, the greater the damage received from the shockwave.
The nerves in my body seemed to burn out.
The same is true for the other crew members. Attenborough, Cybella and Tetukun were incapacitated one after another.
"What, this attack..."
Leeron moaned.
"It's a counter-rotating shockwave. It shocks the Spirals and prevents them from synchronizing with the spiral galaxy. It stops the manifestation of Spiral Power by blocking the force of will..."
