I'm basically going to have the mc be a reincarnation of the full potential of broly, vegeta, goku, vegito, gogeta, gohan, and finally future trunks so that means all of their unique transformations.
1.base form
2.mystic form(it's basically the full body potential of base form)
3.beast form(it's the evolved form of mystic so white gray hair and red eyes with purple aura)
4.great ape
5. Ikari mode(basically the power of great ape in base form, yellow green eyes)
6.false ssj( basically the power and yellow aura surrounding base form)
7. Legendary ssj ( the reason I'm putting this before the rest of the ssj forms is well cause the other forms beats this one by leagues)
8. Ssj 1
9. Ssj grade 2
10. Ssj grade 3
11. Ssj 2
12. Ssj 3
13. Golden great ape( only used as a pit stop and never used again cause it's the first step to achieve ssj4, basically one needs to have their tail, 2 achieved the ssj forms and perfected them, perfected and complete control of great ape form, 3 infuse ssj energy into great ape form, 4 gain control of golden of golden great ape form, 5 finally condense the power into new form presto u get ssj4)
14. Ssj4
15.ssjg
16.ssjb
17.ssjb evolution( it's basically ssj2 but in the god forms)
18.ssjb 3( the reason of this cause somehow goku black made ssj rose 3 it's a godly transformation and theoretically goku could achieve this but it's blue instead)
19. Full power ssj4( it's from the db heroes anime when dbs goku and vegeta infused their god ki into xeno goku while in ssj4 transformation)
Now before anyone says why didn't I put ultra instinct or ultra ego in the transformations but I put mystic and beast in cause here's the thing mystic and beast are not techniques that can't be used in other forms like ultra instinct or ultra ego or kaio- ken, now those 3 are techniques cause in the anime and manga those have been used in conjunction with the other forms.
