Gaist Crusher

Gaist crusher is like a paraody of GaoGaiGar, instead og GGG, it is GCG, the comanders are really simler with over the top posses, and they both have grown ups depending on kids to save people. The kid has special powers in both, and there are a lot of laughs. 

The characters are both hot-blooded but skilled fighters who are always doing what they believe is right. They also have an organization similar to GCG. 

Both are part of a cross-media franchise and meant to promote their videogame counterpart. Meant mainly for kids, they're essentially spoofs from older series, borrowing a lot from their aesthetics, special attacks, transformations while also trying to bring a breath of fresh air on the genre. They're fairly linear and their characters one dimensional ar best but have this broad appeal that could make them enjoyable for different generations of viewers.
