Deathstroke: Knights & Dragons - The Movie

An accident exposes Slade to an experimental drug that grants him super strength, enhanced agility, and rapid regeneration. The treatment saves his life and radically changes his physical abilities, turning him into the mercenary Deathstroke. With his ally William Wintergreen at his side, he begins taking on dangerous missions.

Slade marries General Adeline 'Addie' Kane and settles into a family life. They have a son named Joseph, tying his personal life to his dangerous profession. He continues operating as Deathstroke with Wintergreen's help.

During a mission in Cambodia, Deathstroke meets Lillian and falls in love with her. He completes the mission and returns to his double life, keeping the affair hidden. This romance complicates his balance between family and mercenary work.

Lillian gives birth to Rose, who becomes an orphan when her mother dies in a hit-and-run accident. Rose grows up alone until she is eventually rescued by Jackal who leads a secret organization. The tragedy marks the start of a new line of conflict around Jericho powers.

Jackal, leader of the secret organization H.I.V.E., rescues Rose and trains her to become his successor. She is groomed to wield power within H.I.V.E. and to influence events at Slade's side. Her path becomes central to the future of Jericho and the family saga.

Jackal kidnaps Joseph to pressure Slade into action. Slade returns from a mission to find Addie furious about his secret assassin life and resolves to rescue Joseph. This sets off a renewed chase that tests their fractured relationship.

Slade tracks down Jackal's base and engages Bronze Tiger and an unnamed female operative. He defeats them and continues toward Joseph, but his throat is slit just before he can rescue him, leaving him mute. The injury marks a turning point in his ability to communicate and act.

Joseph is hospitalized after the attack, and Addie breaks up with Slade. She isolates Joseph at a private school to shield him from Slade's dangerous life. The family fractures as Slade fights to maintain his purpose while living without his voice.

Ten years pass and Slade remains Deathstroke, continuing his mercenary work. The H.I.V.E. Queen contacts him, holding Joseph hostage to force his action. Addie reopens the alliance and shares a kiss with Slade, signaling a renewed but fragile reconciliation.

Slade follows intelligence to Colonel Kapoor, then travels to Kaznia to confront Tiger. Tiger reveals that Jackal is alive and that the Queen is located at the Kerguelen Islands. Wintergreen accompanies Slade to the island for the final confrontation.

On the island, Slade is confronted by Lady Shiva and surrenders to the H.I.V.E. Queen. The Queen reveals she trained Joseph to use Jericho, a weaponized psychic ability, and Joseph confirms his allegiance to H.I.V.E. Slade realizes the family is further entangled.

The Queen is revealed to be Rose, Joseph's sister. Slade is shot into the ocean but regenerates and is saved by Addie, who reveals she placed a tracking device through the kiss. Slade also confronts revealing his affair with Lillian.

Jericho's powers threaten to spiral out of control, prompting Rose to help. Slade, Addie, and Wintergreen uncover H.I.V.E.'s plan to use Jericho to control world events and push for a global order. They realize the threat is greater than any individual family war.

Jackal launches the plan with a series of attacks to draw the president out. On a H.I.V.E. plane, Rose and Jericho betray Jackal, while Slade and Addie confront Jackal and Shiva. Rose defeats Shiva, and Jackal's armor blocks Jericho's psychic feints, allowing a final fall from the plane.

Slade places a bomb on Jackal during the fall, appearing to kill them both. Back home, Jericho remembers his father as Addie welcomes Rose into the Wilson family. Slade's body is washed up on a beach, but he remains alive, leaving his fate open to the audience.
