War Titan - Knightus (Solaris Cordax)

Knightus Guardian of DarkIron Isle (After Solaris)

Solaris (Cordax) V1 (Old)

Solaris Cordax V2 (Current)

Knightus - Knightus the Guardian Knight under Guardian Prime, he was put in deep sleep to protect Anna. He's the only Ancient "Guardianbot" standing under Guardian Prime, his order was to keep the Darkiron Isle safe and stop the Black Iron Legion, he was told by Guardian that the Black Iron Legion bots are ruthless under Dark Hound.

Solaris - He was once called Solaris. Solaris was part of the Cordaxies, Cordaxies are like the Prime Protector's (Prime Protector's Under Guardian, with Knightus - and the Guardianbots under Dragon Prime) they were mainly good, however Blade Cordax, (Cordax being like the Primes are leaders. Cordax had the Codex of Hunters / the Hunter's Core) they were Titan hunters mainly, Blade had sent a firing squad to any planet that had a omega threat Titan and had to eliminate them, one of said titans was The Guardian, a remnant of a crimson titan gone wrong, Blade's brother who was experimented on and taken by the Warrior and the Alchemist, Blade was sent to kill him, however The Guardian killed him, and took the Hunter's Core, making him an Alpha threat, he eliminated every member of that the Cordaxies, other than Solaris. Solaris killed The Guardian (rogue titan form) and retrieved the Hunters Core, he took the soul to Entity and made it into the Titan it is now, Entity gave Solaris a choice, to be the new Cordax. Or to be someone else. Solaris chose to hunt, he became Solaris Cordax, but Solaris was ambushed at another hunt by the Black Iron Legion, Guardian Prime found him on a random planet, Solaris was frozen and forgot all memory of Solaris, so he became Knightus, guardian of Guardian Prime, but when Guardian Prime was defeated by Houndarin, Guardian's last words to Knightus was "find a new prime" so Knightus tried himself, but the Prime Core wouldn't choose him, as Knightus already had the deactivated Hunter's Core, so he chose the best person for the job, Aegian. Aegian became Aegis Prime, the second Prime the core had a full bond to, thus making Knightus Protector of "The Guardian" after he resurrected it and it became DarkIron Isle. However when a war broke out between Knightus and Houndarin (Leader of the Black Iron Legion - Dark Hound once he gets the Night Shard), Black Iron Legion developed a gas that would corrupt any organic life so they threw it into some caverns and thus killing almost everything, they then developed one that could stone bots for a period of time, thus leaving the Cordaxies in a forever battle with the ancient Black Iron Legion drones..
