Super Saiyan 3 (Category)

In the first rotation we have SS3 Bardock and SS3 Goku; we want to have SS3 Bardock on both rotations to abuse his support Passive as much as we can and we want to always have SS3 Goku in the middle slot in order for him to always start with 12 Ki by default, he is the hardest hitter on the team and his 18+ Ki Super Attack has priority over anything else.
The second rotation consists of SS3 Bardock and SS3 Gotenks; we ideally want to have the latter in the first slot of the rotation in order to get his 11 Ki Super Attack and possibly take enough damage for SS3 Bardock's Passive to activate (his 30% DEF debuff is actually useful for this reason).
The first floater is SS3 Goku (Angel), a hard hitter with Over in a Flash for SS3 Goku.
Second floater is a support unit SS3 Goku (GT) (Great Ape); this unit works amazingly well with SS3 Goku and SS3 Bardock since they receive their ATK boost upon Super Attack.
The last choice as a floater is not a unit who is part of the category, it's Super Gogeta; even though [Full-Tilt Kamehameha] SS 2 Gohan (Youth) and [Mythic Evolution] SS3 Broly would outdamage him, this unit is a better choice because they lack Over in a Flash and, as I said, getting SS3 Goku's 18+ Ki Super Attack is has the priority.

Because of its nature, the fact that realistically any unit with Over in a Flash can easily fit on it and the second part of SS3 Bardock’s Leader Skill opening up the team to pretty much any Super INT type, building a Super Saiyan 3 team is relatively easy, I will only list a few options.
