Power of the Verse
The vast majority of the verses power lies with Kusuo Saiki having Large Island Level+ to possibly even Planet level Attack Potency, Supersonic speed and a large variety of hax.
Aside from him the characters are at the level of normal humans. With abilities like being normal, seeing and being possessed spirits or fortune telling the other characters supernatural powers have few relevance in direct combat.
Aside from supernatural powers there are some characters with genius intelligence in the verse, most notably Kusuke Saiki who can construct things like the devices limiting Saiki's powers, devices that prevent mind reading or various robots with AI.
Lastly Teruhashi Kokomi, despite having neither powers nor genius intelligence, could be seen as noteworthy due to possessing beauty to the extent of nearly everyone instantly obeying her and the capability to make use of that fact.
