He was portrayed by Alex Klein.
Following the death of the Abilisk and the arrest of Nebula, Ayesha learned that Rocket Raccoon stole some of the Sovereign's Anulax Batteries. Finding this to be a disgrace, Ayesha becomes angry and summons her troops, including Zylak, to pursue and destroy the Guardians of the Galaxy in their Omnicrafts, which they virtually controlled from their planet.
Despite being outnumbered, the Guardians managed to evade most of the Omnicrafts by going through a meteor field, but only Zylak's ship remains in the open, ready to take them down. The rest of the Sovereign pilots crowded around Zylak's screen, encouraging him to kill the Guardians while hundreds of more Omnicrafts were being prepared. However, Drax uses a blaster to destroy Zylak's ship, much to Zylak's anger. The other pilots then insulted Zylak for his failure, leaving him nothing but silent over the scene. The rest of the arriving Omnicraft would later be destroyed by the arriving Ego, who is revealed to be Star-Lord's father.
