Strategic

Zamasu Pothala, paradoxically with his burden, has a "god complex"; referring to himself as the supreme and absolute god. He is so self-absorbed that he refuses to defend himself against Goku and Vegeta in their fight. [8] After fusing, Zamasu's pronoun for personal speech was adjusted again; he now uses "wa" (我), a more pretentious personal pronoun, in keeping with his new personality. He is narcissistic to the point of saying that he is beautiful and his methods will make the world more beautiful, that his justice over humans is correct, that he is beautiful, noble and immortal, mocking humanity, which should praise him, mentioning that a god is someone who looks down and anyone who tries to touch him is greedy and deserves death. On the other hand, Gowas points out that he has a degree of loneliness such that he does not conceive of any other justice. In his fight against Vegetto, the latter is so confident and distracted regarding combat to the point of receiving an open blow from Super Saiyan Blue Vegetto. He is also indifferent regarding the state of the universe and the other lines, annihilating all forms of life, god or human, taking the form of the Universe at the cost of destroying it. This very aggressive effort that he imposed in the future paradoxically made him have to be defeated by the true Absolute God.

Once the fusion is performed, they can no longer be separated again, as indicated by Gowas, the effects of the Pothala are permanent in the Kaio-shin. After having been defeated in a battle he is able to recover and gain a huge boost of power instantly, given that he has Black as his half who had the ability to improve his power with the damage received (Saiyan Power). On the other hand, Unified Zamasu admits to still having the immortality of his other half (Zama), making each cutting blow or mutilation he receives be regenerated in a few seconds and cannot die (when fused with Goku Black, Unified Zamasu lost part of his immortality since Goku Black makes him half immortal and half mortal, for that reason his body is deformed by not having all his healing capacity). This ability together with the ability of the wall of light, which is an aura technique that makes everything in its path disappear. Zamasu has the ability to summon a kind of violet bird that he uses to carry out different ranged attacks and a ring of light with the same purpose as the previous one.

His base state is Super Saiyan Pink, because Goku Black initiated the union with this form, therefore the Super Saiyan Pink of Unified Zamasu is permanent and cannot be reversed, which should reduce his life expectancy due to the expenditure of power, but thanks to his immortality, this flaw is completely eliminated. It is shown that his halo of light is what keeps his power stable. That said, this fusion makes him a very powerful and difficult to defeat being, however, Unified Zamasu presents a weakness and that is that when fusing with a human, the fusion ends up losing a fraction of that immortality so longed for by him, making him more vulnerable to attacks and they can finish him off definitively, this weakness brings with it a contradiction in Zamasu, which causes him to end up mutating into a gelatinous-looking being.
