Ragna "D" BloodEdge
By the Power of Gaia!!!
That's what the Wiki entry says about it, too.
Can I suggest this:
If you feel you were let down, chances are you were reading the *spoilers* thread and knew about it before hand. But those who didn't and knew nothing about it didn't feel let down. You kind of have to watch every episode without knowing the next one. Don't forget, GekiChopper has something of a TAE KWON DO KARATE theme to him and GekiViolet is a KICKBOXER. The main three have a KENPO KARATE theme. They're three different styles but equally as strong as the others.
But it teaches you a lesson: Back away from the spoilers later in the season.
Who?Wait until the 6th ranger comes.
