Unless they replace rider instead of sentai just like in 89 until 96.

I highly doubt they'd replace Rider or Sentai.

Why would they replace Rider?

The Franchise is still going strong. Unless the toys dont sell anymore or the ratings dont get unbelievably low neither sentai nor rider will go away anytime soon.

This subject has been settled numerous times.
There is no indication that a new Metal Heroes series of any kind will be made at all.
One off movies are it.

A guy from henshin justice forum said metal hero will replace sentai.

It'd be pretty bitchin' if they did make a new series, though~

Oh, well if random dude on the internet said it...

No, Metal Heroes as a show is dead. Toei tried seeing if there was any interest with the Gavan movie and that tanked. I'm honestly not even sure why the Shaider and Sharivan direct to dvd movies are happening.

Maybe the Guys behind those movies made such a great pitch that toei couldnt pass it up? :lol

Spielvan was a tear-jerker.
I was six or seven when I first saw some eps on vhs.
Specifically seeing what happened to his family got me misty-eyed as a kid.

Trivia: Spielvan's father Ben was played by Mizuki Ichiro.

Spielvan is one my favorite metal heroes.
