Yuusha-Ou GaoGaiGar, Tengen Toppa Gurren Lagann Recommendations
Both shows are kinda throwbacks to 70s style super robot anime, but Gurren Langan does it with a lot more style and mordern sensiblities. Also, while GaoGaiGar is kinda a superhero story of mythological proprotions, Gurren-Lagann is a coming of age story that takes a super robot stable (drills) and turns it into a metaphor for life, that starts out as a battle for the freedom of those living underground and ends up involving all those who live in the universe, all the while Simon tries to find his own meaning and purpose in his life, and follow his destiny.GaoGaiGar on the other hand, follows
TTGL heralds back to different "eras" of mecha anime, and borrows from GaoGaiGar extensively. GGG should be one of the many required viewing series before fully enjoying TTGL and all of its quirky references.
If you like the super robot theme of Gurren Lagann, then GaoGaiGar has some of the same themes, and even some of the same voice actors.
Extra hotblooded manly mecha! Both series reconstruct classic kid-oriented mecha tropes that seemed to have become outdated but turn out to be lots of fun when intentionally reassembled. They run on manliness and shouting, and when they get a bit cheesy it's all the more fun. Before Gurren Lagann came along, GaoGaiGar was pretty much the standard for super hotblooded mecha anime -- it set the bar that Gurren Lagann had to surpass to be considered truly over-the-top.
Watch the whole series its like Gurren, manly men with many awesome robots and epoic epic battles
