Knight (as one of the The Gladiators
|Age||16 years old|
|Relatives|| Unnamed mother|
In his first form, Death Knight wore a strong and durable armor that made him extremely hard to defeat, yet he was slow (a flaw that the Guardians explored to defeat him). He carried a energy spear that could turn into a sword and a extendable shield. Naturally, he was stronger than an average individual due to the fact that he was one of the Infected.
After becoming a member of the Gladiators, the overall design of his armor changes to be sleeker and more technological armor to match that of Knight. He returns much stronger and is equipped with the same gear. A energy spear/sword that has energy leaking from its blade and when charged with dark energy can deal lots of damage. He once used it to cause a massive shockwave that moved away everything on his sight.
Keith has blonde hair, pale skin, deep blue eyes and bags under his eyes.
Prior to becoming one of the Knights of the Apocalypse, Keith was one of Madeline's few friends and had a lot of common with her. After she joins in the Alpha cult and meets Keith, their relationship gets much closer and they start to develop romantic feelings for each other.
- Originally, Keith would be called "Daniel", then "Jack" and finally Keith.
