The Power Rangers franchise has quite a heinous standard on Pure Evil, but I’m going to say why Singe (Power Rangers) should not be under that category.
Who is Singe[]
Singe is a double agent for Lord Arcanon, who was working with Heckyl/Snide, and was the secondary antagonist from Power Rangers Dino Super Charge.
Why He Doesn’t Qualify[]
While it is true that Singe has quite a sadistic side to him and has no respect for his allies, he’s truly loyal to Arcanon without question. There’s also the fact that in the episode, Freaky Fightday, he became a butt-monkey (someone who is always the butt of a joke, nothing goes right for the character). Also, despite how dangerous he was, he didn’t even get a climactic final battle or have any impact for said final battle, as he and Arcanon were destroyed by Sledge and his crew within seconds.
As far as backstabbing villains go, he’s nowhere near the levels of Darkonda or Deviot, as these two were loyal to no one, and Singe’s loyalty to Arcanon pretty much disqualifies him from truly being Pure Evil.
Final Verdict[]
Cut.
