Antonius Vertech

History and Links
Antonius was created as a Doppelganger to Toon, who just sticks to calling him a Brother, as he technically is one. Antonius and Toon have similar-to-near exact designs, no matter what variation it is. Despite being Toon's Brother, he acts like he's his own entity, and goes on his own missions pretty often. The Splatoon Antonius is pretty much purely linked to his Crossover World Variation.

Relationships to Toon and more
When it comes to Toon....Antonius usually doesn't get along with him well. They have arguments a ton, and most lead to fights. Nobody usually wins, as Ezra gets involved, but sometimes one kills the other, and it's usually Antonius killing Toon, since he has more lives. Unlike normal cephalopods, the Delta 5 can't respawn--excluding Toon. Antonius is the front-charging-take-down-member of the Delta 5, so it's no surprise to see him down on the ground quick when he's overwhelmed. Antonius-being the Co-lead-is usually seen in charge when Toon isn't around-which is very common.

Links to Crossover Antonius
Unlike other Delta 5 members, Antonius is linked to his other versions. He shared this feature with Toon, hence how he knows what his Crossover World versions are up to from time to time. Toon has a more limited version of this abilitiy, though. Antonius' random disappearances are linked to him actually going to the Crossover World if anything. These links are also the reason Antonius is able to do other types of combat moves his Crossover selves knew.

Tartar's Revenge
Antonius-like Toon-was changed to an Octoling within the events of Tartar's Revenge. He had the same ink color with the default Octoling boy hairstyle, plus the fact he now had a denim shirt, blue sea slugs, and now crimson red eyes.When he first encountered Toon after being released, he was seen being thrown over a cliffside by the other Octoling. Recent searches led by Shade showed that...well...Antonius had actually lived, just with a long scar running from his back to his face, barely missing his right eye, plus other numerous scars left on his arms and legs.

After time of recovering and losing Toon once, and twice soon after, then having to kill him due to the VA, he went after the trio himself, and lost his powers in the process. After all of this, he went on his own adventure, convincing Calypso to join him. They made their way to Octo Valley, where a set trap killed the Octoling with a mechanism that was relatively similar to how Fox Traps worked, which caused the Vertech to die of something similar to blood loss, even after being freed by the albino.
