Perhaps the most major villain across all of Power Rangers, Lord Zedd was the main antagonist in Mighty Morphin’ Power Rangers, and also featured heavily throughout Power Rangers Zeo and Power Rangers in Space.
In Power Rangers canon, Lord Zedd and Rita Repulsa marry, and have a son, Thrax, who also made an appearance in Operation Overdrive, part of the Power Rangers 15th Anniversary special.
The first Power Rangers movie served as a reboot of sorts; new Rangers, new backstories, and new suits, but the movie still still stayed true to its Power Rangers roots, most notably in including a classic villain from the Mighty Morphin’ Power Rangers, Rita Repulsa.
Going forward, the future of Power Rangers is unclear, but there were plans for at least one more movie, as teased in a Power Rangers post-credits scene.
