Tengen Toppa Gurren Lagann, JoJo no Kimyou na Bouken (TV) Recommendations
If you're looking at these two as a comparison of similar anime stories, don't, there isn't one. Instead look at these two as having a similarity of overabundant histrionics (lot of shouting and overacting) and male characters that are very gar.
The storylines are simple within themselves.
Just remember that these two series are both over-the-top, so be ready for it.
What if I'm so manly that I drill open the sky?
Purposely done over-the-top shounen series with positive outlook on the general flaws of humanity when they are fighting supposedly ten times as powerful alien monsters.
Supernatural characters who start out as weaklings constrained by their naiveness, and though Jojo develops its characters through generational heritages, both display a trending possession of glorified characters.
Mostly fluid action scenes. TTGL is more mecha, whilst Jojo goes back to the '80s battle shounen genre. Overall, vastly epic action scenes and great music.
Both are highly potential, likable butlers for macho men with interests
If you liked Gurren Lagann for it's over the top manliness and balls to the wall insanity then you will probably love Jojo's Bizarre Adventure (2012) as well.
-Both shows have over-the-top characters and plot lines
-Both shows involve manly men fighting for the fate of the world
-Both shows are badass in general.
The only major difference in the two is that Gurren Lagann is a mecha and has plenty of Fanservice, while Jojo is a shonen and has manservice.
Both are incredibly over the top and manly action series that throw logic out the window at every given opportunity in exchange for sheer awesomeness!
"I WANNA PIERCE THE HEAVENS AGAIN, DAMMIT !!!"
I get what you mean, bud. JoJo starts at ground level, unlike TTGL, but from there they both rocket up to the skies, past the galaxies and beyond, hitting the most epic peaks one could ever dream of
JoJo is well known for being the origin of many common battle shounen traits, and I have yet to see another series where this is more true than in TTGL
Hamon energy is essentially Spiral energy.
The main characters overcome unbelievable odds with sheer force, will power, and their hidden power within.
Both shows will make you lose your mind and keep you on the edge of your chair trying to guess what happens next.
Both are completely over the top shounen in almost every aspect. Crazy fights, world, characters and music abound. If you want a show that can and will do everything these are for you.
