SSJ3 Goku is a unit with a Passive that supports a specific category. He was given as a gift from the developers of the game to all players in celebration of the 3rd Year Anniversary of Dokkan Battle. If we look at the individual unit he is really good: he is of course not meant to deal damage with his low stats and multipliers, but his Passive is even better than Inklings of Ultimate Power Super Saiyan 3 Goku (GT) (Golden Giant Ape)'s, that gives "only" a 33% to ATK, on a "SSJ3" team, and it's actually one of the best support passives in the game. Where is the problem with this unit? The name: Toward a Distant World - SSJ3 Goku has the same name as the hardest hitting unit on the team, Golden Fist - SSJ3 Goku, meaning they can't be used together. While the argument that not everyone can have Golden Fist - SSJ3 Goku could be made, I want to remind you that the second best option on the team with that name would still not be this unit, but Mystery Super Technique Super Saiyan 3 Goku, who has recently received an Extreme Z-Awakening, and is readily available for anyone in the Baba Shop in exchange for the Red Dragon Stone that every player has received as a gift less than a month ago.

"Super Saiyan 3" Category Ki +3 and HP, ATK & DEF +33%
In case you don't have Golden Fist - SSJ3 Goku or Mystery Super Technique Super Saiyan 3 Goku then you can run this unit on a "SSJ3" team. Toward a Distant World - SSJ3 Goku can also be used on a Super INT, but his Passive would not be as good there unless you were running SSJ3 Bardock and SSJ3 Gohan together with him.
Super Attack
SSJ3 Goku has incredibly low stats, a low multiplier and lacks "Fierce Battle", he's not going to perform well offensively.
Leader Skill
If you want to run a "SSJ3" and you don't have SSJ3 Bardock, the actual Category leader, then you could use this unit and a friend SSJ3 Bardock, but since the team doesn't really struggle with Ki, there is little to no reason not to use A New Legend Begins Super Saiyan Bardock's Dokkan Awakening instead of him since he gives 7% more to all stats and boosts also INT, AGL and PHY types as well a the cost of 1 Ki less from the Leader Skill.
Passive Skill
As I said the Passive Skill is really good, 33% to both ATK and DEF to the "SSJ3" Category with no restriction of any kind. Giving Ki is not really needed, so excluding the lack of "Fierce Battle" and the case of homonymy, he is the best support unit for the team.
Link Skill
This unit’s links are pretty much what you would expect any “SSJ3” to have: “Over in a Flash”, “Experienced Fighters” and “Super Saiyan” are all very good links on his team, but Toward a Distant World - SSJ3 Goku noticeably lacks “Fierce Battle”.
These two units activate “Experience Fighters” and “Super Saiyan” for each other, and, since SSJ3 Bardock gets no DEF before attacking, he’s going to take hits a lot better with this SSJ3 Goku on rotation.
Since SSJ3 Goku (Angel) has no way of increasing his DEF, he can greatly benefit from this unit being on rotation with him. 33% from the Passive and 20% ATK from links activated is not bad, but there are still better options in terms of links on the team.
Hidden Potential
I would not advise anyone to put orbs into this unit, since he is not meant to do damage, but if you have some spare orbs, then a good blend of Additionals and Criticals should be the right way. The unit already gets a lv.5 Dodge that sort of makes up for his incredibly low DEF.

Should I use Elder Kais/Grand Kais?
This unit is not farmmable, but it’s very likely that we are going to get more copies of him and a Dokkan Awakening in the future, so no Elder Kais/Grand Kais should be used on it. The damage that SSJ3 Goku outputs is honestly not enough, even at max Super Attack, Elder Kais would be a waste on him.
