This week's episode of Gokaiger features the return of two actors from the series Chouriki Sentai OHRanger. To warn you, there are Spoilers if you see the images down below.
Chouriki Sentai OHRanger has a somewhat interesting past. This series was originally going to be an anniversary series, and several original Super Sentai writers where coming back to write for the series again. The series was going to feature a much darker theme, but because of the Terrorist Sarin Gas Attacks on the Tokyo Subway system, the series received a somewhat unenviable alteration, removing violence and destruction, and scaling the series back to something less darker and more child-friendly. So that may be why I think the series had the somewhat incompatible presence of a military organization, next to the what could have been much more scarier and serious robot invasion from space. I can't speak for how it's regarded in Japan, but I've heard it was one of the less popular Sentai series. Which seems like a real shame - as it looks like it had a lot of potential.
For Americans who are more similar with Power Rangers, you might notice that the costumes and footage from this series was used for Power Rangers Zeo (where Power Rangers finally ditched the attempt to hold onto the Dinosaur costumes of Zyuranger.)
Of the images I got for this week, there's a Liveman image you can find all the way down at the bottom of the post. Also, there was a screenshot of GokaiSilver in his cockpit, but complete on it's side. (I assume it's during a battle, with different angles showing damage to the robot) I rotated it, and I thought it showed a rather nice larger-scale view of the cockpit.
