At Universe 0 in Callio, Zaydon was leaving early to meet up at the dark forest with his mom. He was walking through the fog and felt chills behind him.

Zaydon: I should find me a jacket after my training.

Suddenly, he sees his mom sitting near a campfire and starts sitting next to her.

Lia: Zero, you should try to spend time with the others at the castle.

Zaydon: Actually, I came here to improve my dark form and see if you can help me with that.

Lia: I will try, but I want you to fall asleep while you transform into your dark form.

Zaydon was resting on the ground and falls into a deep sleep until he was in a vivid dream. Once he woke up, he found himself on Callio and senses a familiar presence.

Zaydon: Why am I back at my hometown? Wasn't I training with Mom?

???: It's good that we have finally met at last.

Zaydon turns around and shocked to see Tarro.

Zaydon: Tarro, what are you doing here?

Tarro: I could say that I am looking for something important. You seem to be a descendant of mine, but you don't feel like it. Tell me, when was the last time you actually had a dub alone?

Zaydon: It's actually around my first fight with Aladdjinn.

Tarro: You mean to tell me that after your second fight, you was killed by him! I have injured him until he was unconscious and what did you and the rest of the family do?! I have rule this kingdom and all of my descendants just recreate the Game Of Thrones with The Lord of The Rings by ruining my legacy!

Zaydon: Look, I may have caused a lot of problems, but I was the only one that fixed it.

Tarro: Which I'm proud of you for that. Also, I know that Aladdjinn used your body and created his children through magic. I may be angry at you and Aladdjinn for that, but I know that the kids are getting stronger than your own kids which I would be proud of since they never done anything except complaining.

Zaydon: Don't you think that you're acting kinda harsh towards your descendants?

Tarro: Tell me, what are they gonna do when they see me? Do you think I am afraid of a reaper, a God, or a powerful opponent?!

Zaydon: Tarro, just chill. I'll start improving my dark form and fight you with it.

Tarro smirked at this challenge and starts stretching.

Tarro: Azure Zero Mezuré Zaydon, I want you to not hold back anything that you got.

Zaydon uses Ultra Instinct and charges towards him until Tarro dodges his fists and kicks him in the stomach. Zaydon punches him in the face and jumps backwards to shoot ki blasts at him. In a distance, Tarro looks up and smiles at Zaydon.

Tarro: Good news, one of your daughter has a dark form finally. She may have lost consciousness, but you and her grandma could still train her.

Zaydon: Fine, but I should tell her and the others something about my death from last time. Let's continue this now and learn something about the dark form that everyone in my family have it.

    Tarro kicks Zaydon upward into the air and throws him into the water until he fires ki blasts at him. Zaydon appears behind him and staggers Tarro's back with a strong attack.

Tarro: Alright, you seem to know the basics of the dark form and how it's used. What if I told you the effects it wears off and how much stamina it drains?

Zaydon: What are you saying?

Tarro: When you first used the dark form, how did you feel?

Zaydon: I felt exhausted, but I feel like my powers, ki, health, and stamina has increased.

Tarro: I want to know something else about you when you have a chance to kill your enemies. Why didn't you fight them in your dark form?

Zaydon: I want them to have a good chance to fight me so I can learn about their weak points and time myself to strike when they're open.

Tarro: That's interesting. Now, I want you to transform into your dark form and go check on the others.

    Zaydon was breathing heavily until his eyes turn yellow and was surrounding himself with a dark aura. Suddenly, he screams as his hair turns and has glowing red markings around his body until lightning starts to spark around him.

Tarro: Go now, and help the others out.

     Zaydon nodded his head and starts to wake up to see his Mom carrying him to the castle.

Zaydon: Mom, I need to check on the others.

Lia: Alright, just try to stay safe.

    Zaydon created a black hole and walks towards Luna's location until he spots Hinata.
