Some toys just weren't meant for television.
Tyco introduced the Dino Riders in 1988, and licensed the product to Marvel for not only a comic book miniseries, but a short-lived animated series that was a component of Marvel Action Universe, a weekly syndicated anthology series that Marvel had released. The comics came out after the series had ended.
As with Sectaurs, which we looked at yesterday, we never saw the show when it first came out, so there isn't a rating. Take note of the animation in the first couple of minutes of the opener, as this was inspired by A-Ha's 1985 video, "Take on Me".
