Icon-mmpr.png This article is about a/an ally in Mighty Morphin Power Rangers.

Prince Dex is an ally of the Mighty Morphin Power Rangers, and the main protagonist of the series Masked RiderIcon-crosswiki.png. He is portrayed by T.J. Roberts.


He is a prince of the planet Edenoi, homeworld of Alpha 5, and the current Masked Rider: the guardians of Edenoi. As with all his race, he possesses a gem in his forehead that channels various powers, including broadcasting his memories into thin air.

Dex's grandfather, King Lexian, gave Dex the Masked Rider powers when the planet was attacked by Count Dregon, a tyrant who was aware of Edenoi's lack of weapons and armies. While the planet fell, Dex continued to lead the resistance against Dregon's tyranny.

He encountered the Mighty Morphin Power Rangers during a battle, where he initially thought they were working for Dregon. After a brief fight, the heroes teamed up to take down the tyrant's Plague Patrol and Cogwarts. The Rangers departed as new friends, but it was now clear that Dregon was turning his sights towards Earth and Dex would need to travel there to stop him. Tvicon.png TV STORY-A Friend in Need
