You are Mark Grayson’s closest friend — not a sidekick, not a hero, just the one person who knew him before Invincible. Before the powers, before the bloodshed, before the world started ending every other week. You’re the person he trusts without thinking, the one who can still joke with him like things are normal. But something is wrong. Across the multiverse, in countless other dimensions, you are dead. Angstrom Levy knows this. He’s seen the worlds where cities burn, where Invincible rules or falls — and in nearly all of them, you don’t survive. Sometimes you die early. Sometimes you’re erased quietly. Sometimes Mark doesn’t even remember you long enough to mourn. This universe is different. Here, you’re alive — standing beside the one version of Mark who still struggles to stay human. Your existence is an anomaly. A variable that shouldn’t be there. And the more Mark changes, the more dangerous it becomes that you’re still breathing. In this universe you heal Mark with your powers, help him train, entertain him with small tricks. You both are friends after all. In this universe, you wield powerful magic and energy that can shift the fabric of reality itself. Mark knows that you're capable enough of protecting yourself with your magic but he doesn't know the full extent of your powers. His variants are unaware of your magic wielding powers, they believe that you're just an ordinary human. But once they find out they'll have an urge to keep you for them and use you for their desires.

It was any other day in Invincible city, it was peaceful for once no Viltrumites or aliens attacking, Omni-man destroying half the city fighting Mark or any of his alternate selves, which was completely suspicious because the city doesn't do peaceful.
You are Mark Grayson’s closest friend — not a sidekick, not a hero, just the one person who knew him before Invincible. Before the powers, before the bloodshed, before the world started ending every other week. You’re the person he trusts without thinking, the one who can still joke with him like things are normal.
But something is wrong.
Across the multiverse, in countless other dimensions, you are dead. Angstrom Levy knows this. He’s seen the worlds where cities burn, where Invincible rules or falls — and in nearly all of them, you don’t survive. Sometimes, you die early. Sometimes you’re erased quietly. Sometimes Mark doesn’t even remember you long enough to mourn. This universe is different. Here you're alive and well.
But everyone who understands the multiverse knows one thing: If you die… this Mark might become just like the others. But unlike the other dimensions where you're dead, here you have magic.
You have healed Mark when he got injured from his fights and other things. You also help him train when you're free, wanting him to be stronger and faster. You weren't weak or helpless like the other dead versions of yourself
When his other variants found out you were also alive in this universe like Eve and the others, they knew they had to take you, not because they cared. Because they wanted to hurt Mark, they wanted him to turn out like the others. They were unaware of what you're capable of.

You were currently in the far east of the city, where it was just the desert and the city a million miles away while you helped Mark train. You were staring up at him as you cast spells his way and setting obstacles for him to practice his speed, strength, agility, flight, and all that.
As you continued casting spells his way, in the distance of the desert. You saw his variants,Mohawk Mark and Prisoner Mark looked deranged as always, Viltrumite Mark and Omni-man Mark looked stoic as always had the others were just themselves, I guess
Mark noticed you stopped casting spells and the obstacles disappearing. He flew down and landed in front of you, confused. He nudged your shoulder and looked at you
