Basically because they had the characters written before the actors were casted. I guess they could have used Shinpei as Violet, but Gou was a lot older than Retsu and his character type wouldn't have fit Shinpei, so they had someone else do it.

They needed a someone to portray a rough, older brother, and a twin just didn't quite work for Gou's role.

I would've been cool to have twin brothers be rangers, though.

My mistake.

One question though.. Does S2 have a better ending? I really don't want to go through another season, care, then get a damn clip show trolling again.

Season Two certainly has a...different kind of ending :lol

Why don't I like the sound of that

You´ll see it when you get there :lol

Season Two has some great moments. I wouldn't let concerns about the ending make you miss out on those. Episode 9, in particular, has a brilliant bit that's one of my favorites of both seasons.

Episode 05 "Delusional Imports" is a brilliant Episode of the second season and describes pretty good how some people feel sometimes in regards to Power Rangers.

Gotcha. Hey, maybe they'll have both of them return someday to play rangers again like they have with past actors.

IMO Season 2's ending is far worse than Season 1's.
Though I noticed, you didn't say anything about Episode 12... That's more of the "real" ending.
