I came into the rider fandom around decade, I didn't know it like that before.

Well Kuuga was the first ever Rider to be labeled a Heisei Rider so yeah it was around before Decade :)

No one? Really? I am sure there are others that have pointed out that riders from the Heisei era are labeled as Showa. I hardly doubt that I am the first.

But I digress. Enough rider talk in the sentai thread

Getting back to the threads topic, anyone else keep up with Gaoranger through Go Onger as if its the Disney Era? Just a way I remember the series names I guess.

How is it decided whether additional members are part of the primary team, or 6th/extra/others?
Like, why are characters like Big One, GekiViolet, and GekiChopper treated as part of the main team, but characters like AbareKiller, the Gouraigers, or Beet Buster presented as if they were 6th or extra rangers, despite still being introduced later in the series?

Or how someone like Abarekiller is considered a sixth ranger when he's the fifth member of the team.

It was Big One vs AbareKiller that actually got me thinking on the question, really.

Id like to know why AbareKiller is considered sixth yet GekiChopper isnt. I mean Red, Blue, and Yellow, then a fourth member, Black/Violet, then the fifth member who is primarily white and has his own mecha, one is considered sixth, the other a basic team member. Always confuses me.

I guess it's because AbareKiller was a villain first, but I don't think that's a solid reason...

There was a Geki Black (I have not seen all of Geki so yeah...)
