Destructive Capacity: Multiverse level+ (the Anti-Spiral created their own universe in the form of the Super Spiral Space as well as the multiversal labyrinth where a massive number universes are created every instant and are made real when they are perceived, it's also revealed in the complete artbook of the series that the Labyrinth contains multiple multiverses with mentions made to Yoko's multiverse while she was trapped in the Labyrinth along with glimpses of Simon's multiverse before he broke out of the Labyrinth) | At least multiverse level+ (casually maintained the Multi-dimensional/Multiversal Labyrinth that contains several multiverses, powered up even more against Super Tengen Toppa Gurren Lagann)

Standard Equipment: Nothing notable, although he can use his powers to create weapons like the Grand Zamboa
Intelligence: Thorough knowledge of Spiral Power, experience fighting many Spiral beings, controls a civilization and coordinates its war efforts
Notable Attacks/Techniques:

- Multi-Dimensional Labyrinth: Reads the minds of his opponents and then creates a multiverse to put them in that will fulfill their dreams and fantasies; the multiverse also evolves and expands as they are perceived a.k.a. when the teams thoughts shift; the Anti-Spiral thought no sentient beings could escape but the Dai-Gurren Brigade managed to.
 
- Dimension manipulation: Not a named attack or technique, but the Anti Spiral can create, destroy or travel through dimensions.
 
- Reality Warping: Again, not an actually named attack but the Anti-Spiral can shape reality to it's will such as creating pocket dimensions where thought is given form and giving itself various abilities. The most notable technique is creating the Grand Zamboa mecha the Anti Spiral used to fight Tengen Toppa Gurren Lagann.
 
- Probability Missiles: Missiles that can alter reality and increase the chances of them hitting.  

- Infinity Big Bang Storm: In Grand Zamboa form, he grabs two galaxies in Super Spiral Space and combines their energy to create a blast that is supposedly as powerful as the Big Bang.
