Originally, Sparratus was just an ordinary spider living in the Gorge of Eternal Depth until Chi dropped by Laval caused him to evolve along with other spiders and the scorpions and bats, and they gained an intense hunger for more Chi. They captured Crominus and Crunket and took them to the surface where they were showed the source of Chi, Mount Cavora. They then blocked up the falls so they could steal all the Chi, but were interrupted by the Tribes of Chima.
Sparratus trapped the Gorilla and Rhino Legend Beasts in their canyon when they were distracted by the eight Chima heroes in a giant fly, which was really Rogon's Rock Flinger disguised as a fly, where Sparratus was paralysed by Spinlyn's ravishing beauty before they tried to devour the fly. Sparratus realised it was a trick and used his Spider Stalker trap the Gorilla Beast, only for Gorzan to stop him. The Spider Stalker was then brought down by the Gorilla Beast. They captured Eris, but Rogon and the Rhino Beast rescued her.
Sparratus later got his own Speedor and tried to race Laval, but was beaten when he and his fellow spiders they got caught in their own webs.
Sparratus later fought the eight Chima heroes outside the Scorpion Cave, but was knocked down by the Rhino Beast. He was tricked by Gorzan into letting his guard down and getting hit by his punching weapon.
He later fought them inside the Scorpion Cave only for it to collapse. He did not make it out, but he survived.
He later tried to attack the Ice Tribe, but got frozen.
After the Great Illumination, Sparratus and the Crawlers were turned nice and became friends with the cured Hunters and Chima tribes, celebrating Christmas with them.
