Death

Zip is a Sonic.EXE-esque entity, derived from the concept of death. Only problem is that he was created inside the Sonic universe, so there's only scattered deaths to sustain him. He works along the others, each assigned a different horseman of the apocalypse. This is gonna be a running theme with this guy. Be warned lol

It isn't manevolent, not in any sense of the world. Zip does what needs to be done, and seldom loses his temper. He can keep a cool head in most situations unless something he cares about is on the line. Which, y'know, is rare, but it can happen.

He oftens finds himself watching Mobian life from a distance, only intervening when needed. Y'know. Reaping souls n' all that. With that in mind, this guy can't exist without life. He needs people to die for Zip to live. A tradeoff of sorts.

In the beginning, Zip was a faceless entity. It wandered the plains of a not-so-future Mobius, untouched by any .EXE entities or malicious souls. It, along with three others, worked together to balance out the world they found themselves in. Things were calm, until one day, a certain blue hedgehog began making headway across the plains of Mobius. Time and time again, he avoided the clutches of death. Month after month, Zip became enraged. Did this little creature ever know when to give up? He never did make himself known to Sonic or his allies. Instead, he began increasing his efforts to enact the hedgehog’s demise.

Every single one failed. Finally, after what felt like eons, Zip snapped. On that fateful winter morning, Zip found the blue blur seated in the vast expanse of the Green Hill Zone. The battle was unlike anything Zip had fought before, but with increased effort, Death emerged victorious.

As a trophy of its victory, Zip took on Sonic’s form. It was never used to the physical strain put on it by moving bodies, so it was quickly deformed into what we see as Zip nowadays. Alongside Zip, his three companions took on forms similar to his own.

For a time, the four were content living in their ruined wonderland, with nothing to watch over or monitor aside from the occasional survivor. Until recently, Zip saw things change. The world around him crumbled and fell, and with time, Famine fell ill. Needless to say, there was a bit of a panic within the group. After some loud arguing and panicking, Zip stated that he’d go back into the past and find out what, or who was causing this. After all, Famine was his best ally.

TL;DR: Mobius indirectly causes a ripple effect that causes Zip's pal to become hella ill so he teleports into the past to fix that shit

• Zip is totally hollow, there is nothing inside him. No souls, no organs, nothin.
• Can cause matter to decay, but can't make it fall apart completely unless it's dead or just. Not living. Like a table.
• Needs to eat, does so by absorbing material. Reference: mushrooms
