What is the name of the actor who portrayed the original Black Ranger?

The actor who portrayed the original Black Ranger was Walter Emanuel Jones.

Jones played Zack Taylor, the first Black Ranger in Mighty Morphin Power Rangers. Zack was one of the original five teenagers recruited by Zordon and Alpha 5 to defend Angel Grove, and he was known for his dance-based fighting style and upbeat personality. Jones's performance helped define the original team's energetic, youthful tone.

Jones left the series during its second season following a contract and pay dispute. Johnny Yong Bosch then replaced him as Adam Park, who inherited the Black Ranger role. That change is why viewers sometimes remember Adam rather than Zack when thinking of the Black Ranger across the franchise.

The other choices identify different original Rangers. Jason David Frank played Tommy Oliver, most famously the Green and White Rangers; David Yost played Billy Cranston, the Blue Ranger; and Austin St. John played Jason Lee Scott, the original Red Ranger. Jones later returned to the franchise in guest and voice roles, including appearances connected with later anniversary-era projects.
