Robo Knight was created by Gosei to be a protector for Earth and was dormant until needed. However, once activated by the Earth's own will, he became distant and cold and thought humanity did not deserve his protection and only the planet itself did. However, once interacting with the Megaforce Rangers he became kinder to humanity. Also he did a rap.
Robo Knight is probably the only thing from Megaforce I'd say I liked. His character was decent and I LOVED his design.
I think both aredecent, both actors do a decent Robo Cop-esque voice and cold delivery. Chris gets a clunky delivery here and there (though that might be more the writing than him) while Richard I feel is a little light on some lines and he never raps so that's major points against him,
