黄金勇者 I watched Goldran in Cantonese so the experience I get may be a little different than you, but it is the same anime. Goldran is really childish, soft-hearted, and not the serious mecha fight anime. The robot combinations are pretty darn impressive, And everyone of them with a "heart of gold" (LIKE TOTALLY GREAT guys, character) THEY DO LOOK INCREDIBLE !!! The Goldran robots are initially sealed in power stones scattered across the globe. Most of the robot team are unlocked early on by the kids in the anime. Within countless battles are the bonds that grow and the strength to fight together. And finally thesecond half, the REAL adventure begins. And a deeper friendship path.

tl;dr The Goldrans that appear are SUPER INCREDIBLE ROBOTS !!!
