Following "Dendoh", Sunrise took a final stab at resurrecting the Brave style of television series by having some "Dendoh" staffers return to work on "Machine Robo Rescue", based on a modern-day reworking of Bandai and PLEX's own Machine Robo toy line. "Rescue" combined all of the basic storytelling tropes of the original six, kid-friendly Brave series with a truly vast toy line and an early Sunrise attempt at blending 2D animation (the characters) with 3D animation (the robots). While the toys were popular and the anime did well with older audiences, the 3D animation was widely criticized, and overall the effort failed to recapture the original popularity of the Brave Series. Sunrise would not attempt another 2D/3D series until 2006, with the well-received series "Zegapain".
