On that note, how will they justify the Hyper Goseigreat without Datas?

Justify how? They can either skip it in the show, or just change the footage a little. Wouldn't be all that hard.

All they'd need to do is cut Datas's backflip from the combination footage and edit in the motorcycles or whatever it is they're replacing him with.

Exactly. Wouldn't be all that hard. Though I was talking with OOO and are still confused why they cut him out. It would've been a nice homage to Alpha 5. Also confused why they took out Gosei Knight and replaced it with Robo. They kept the names of everything else. Gosei, Gosei Great, and on and on. But that they change. What the French Toast.

No Dice-O to merchandise, no reason for Datas? I dunno.

GoseiKnight becoming RoboKnight is kinda odd, considering they decided to keep so many other "Gosei" words. Perhaps to make it 100% sure that they're not going to pull a Sam/Omega Ranger again?

Why? What was wrong with Omega?

No characterization, no interaction with the others, no character arcs. He just stood around the base sometimes, and fought.
He was practically a non-character.

Good point. They could've cut him out all together and just had the motorcyle come out on it's own.

Hopefully RoboKnight will keep some of his early environmental terrorist ways...

I hope so. Gosei Knight was a badass.
