Prologue A demon reborn
In the land of slugterra, a world of magic and wonder also lies cruelty. Dr, Blakk had kidnapped an orphan and integrated him into the ghouling program. Now instead of a normal Elf, he is a ghoul. (Think in terms of face the dark slinger when Juneja first showed up.)
Instead of corrupted slugs, he wields augmented slugs. They are stronger then ghouls. The reason black gave them to him, was to make him his weapon. His blaster is identical to Diablos Nacho and his second blaster is a staff blaster, much like Master SHanai, his uniform was just like the dark slingers except his gauntlets were retractable swords, not blasters. The poor kid had knowledge inserted into his brain in the form of energy. But one day during training, he and his slugs found out how to escape. They took a wolf Mecha and ran. He didn't even look back.
Needing a place to lie low for a while, project D-X-2-3, or Renegade as he had come to call himself went to the mushroom forest, making a small cabin there. He and his slugs lasted for a long time.
One day he found the enigma slug, and the day after that slug hunters came and started destroying his home. Next thing you know he joined the Shane Gang. He views slugs as sacred artifacts, not tools, so when he encounters someone who treats a slug badly they wish they were never born.
But now he was face to face with black and the emperor. Seeing that the emperor was taken care of by Juneja he pushed himself and black into the portal, where only the emperor knows. Only two can travel and he had just ruined the employee's chances of another conquest.
And that is the tail of the dark slinger, demon of light, and creation of Doctor Thaddeus Blakk.
