Robert Axelrod, the veteran character actor best known for voicing Lord Zedd and Finster in the long-running kids TV show “Mighty Morphin Power Rangers,” died Saturday at age 70, his agent announced on Twitter.

In addition to the villain Lord Zedd and the monster maker Finster in the “Mighty Morphin Power Rangers” series (and 1995 movie), Axelrod also voiced characters like Armadillomon and Wizardmon in the “Digimon” anime series.

Axelrod got his start as a guitarist in the early 1970s before moving into voice work in TV and film. According to his agent, he created more than 150 characters during the course of his career.
