Chosen as the Avatar of the Spider-Totem, Peter Parker is the dark guardian of destiny doing the bidding of the great weaver of fate... a role that has shattered his mind into multiple personas. Arachknight is a Marvel character that appeared in the Secret Warps arc where the immense power of the Infinity Stones is. Where, after the universe was folded and unfolded in half, a warped world where characters mixed with others in terms of identity was created. Examples are Stephen Stange (Dr. Strange) becoming mixed with Steve Rogers, forming Soldier Supreme. Or Moon Knight being mixed with Spider-Man, forming Arachknight. This pocket dimension itself is called the Warp World. It's also called Mergiverse.

Prodigy-level geneticist Miguel O’Hara gives himself spider-like abilities in an experiment gone wrong. He sees an opportunity to protect ordinary people against abusive corporations, and decides to use his powers for good and become Spider-Man of the year 2099. Genetically imprinted with spider DNA, Spider-Man 2099 has superhuman strength (letting him be able to lift 10 tons under optimal conditions), speed, stamina, reflexes and agility, and enhanced durability. Spider-Man 2099 can jump up to 30 feet. He has enlarged canine teeth (fangs) which can secrete paralyzing venom. His fingers and toes have retractable talons used for climbing walls and rending substances as durable as cinderblock. Both of his forearms contain spinerettes capable of releasing adhesive strands of a webbing-like substance from the backs of his wrists.
