The Shadowed One was an individual of unknown species and the leader of the Dark Hunters. Among other unusual traits, the Shadowed One had the ability to kill almost any carbon based lifeform using beams of Radiation fired from his eyes. The Shadowed One often used this ability to execute members of the Dark Hunters who displeased him.
After the Piraka attempted to overthrow him, the Shadowed One attempted to execute Zaktan using his eye beams. However, for unclear reasons, the beams did not kill Zaktan but instead caused a massive mutation in his body, whereby all of his body's cells were transformed into a mass of prokaryotes, held together by energy. This resulted in Zaktan gaining the ability to liquefy his body at will, making him incredibly hard to kill. Zaktan quickly escaped the Shadowed One after the incident.
