Gladiator

He was born centuries ago, though the time period remains unspecified. He is said to descend from a proud bloodline, though the names of his ancestors remain unknown. He was raised by the Strontian council of elders. They were as much family to him as his blood relatives.

Kallark was a cadet on his native planet Strontia, training with other young Strontian men and women, competing for the title of Gladiator. Kallark proved himself an honorable person as well as an efficient soldier then.

Later, Kallark along with the only nine other cadets to have completed the training mission were informed by the council of elders of the purpose of their trials: The new Imperial Guard of the Shi'ar Empire would include the finest warrior of each race of the Empire as its representative. The ten Strontians underwent an enhancement process to become Gladiator, granting them even further powers than those of their kind.

Kallark was later named Gladiator, Praetor of the Imperial Guard, and became a Majestor of the Shi'ar Empire soon after.
