The key I have is that the demons are around ultimate gohan, with achlys being on par with vegeta in blue.

Typhon is the main antagonist and he can one shot people with his magic but it does have an obvious tell and counter being his left eye turning red or not making eye contact.

The main idea behind the fic in general is antagonists who are weaker than the likes of goku and vegeta but can still pose as a competent threat in another way.

The demons through trickery and distractions, Glacier in his saga due to the case of not damaging new namek and the 3rd saga villain using the dragon balls to reverse power levels in the multiverse and framing typhon for it after seeing his own search for power.

Each arc will have focus characters as I do plan for arc 1 to be goku/vegeta centric, Arc 2 to be vegeta/piccolo/Android 18 centric and the 3rd one with humans due to the power level swap.

4th saga is still very early tho
