Same as the first the Malicious Regime invade the world and like the first three people are leading the attacks.

However it wasn't long until this world Union were kneeling before the three. All three were also reveal to be family members.

The first to introduce is a woman wearing teacher dress: this woman have the face of her mother Mako but the eyes and hair like Gamagōri and her name is Mami.

The second to intro is a man wearing general clothes: this man have the face and hair of his father Tatsumi but the eyes of his mother Mine and his name is Timothy.

The final to be introduced is a woman wearing full Shinobi clothes thus her identity is hidden however her eyes is the same as Hibari and her name is Oyuki.

Same with the first world the three people knock out their alternative families then send them away before wiping out this world Union.

Union world 3:

Main: Mha.
Secondary: Dxd, Rwby.
Third: Dc comics, Marvel, Invincible.

Like the last two worlds this world were attack by the Malicious Regime but instead of three it was a single person leading the attack.

Even though the three forces: Justice League, Avengers, and guardians of the globe try their best they were outmatched by the leader.

The leader is know as Agnar who is the co leader of the Annihilators. Agnar appearance is similar to Omni man but the difference is that his suit is color differently and have the Annihilators rank 2 symbol in the center. Unlike the others who knock out the alternative families Agnar kill all who stand in his way. Thus he earn & gain the title: Agnar the Bloody Barbarian. Although these mirror reality people are purging Union worlds there are more than these seven that started to introduce themselves.
