Edo Madara is immortal with unlimited chakra, their only hope would be Gedo Mazo or Izanami.
Round 1: In Character
Round 2: Bloodlusted
Setting The Forest Moon of Endor
I highly recommend you read the Gantz manga, It's way better then Attack On Titan. The anime is alright, but it's not that good because it only covered about 90 chapters. Yu Yu Hakusho is another great series with both the anime and manga. If you're into comedy i would also give School Rumble or Azumanga Daioh a try.
I think the Kudos have a shot.
Lelouch has better feats.
@ImDictatorBowDown: We don't know the size of our universe, only what we can see aka the known universe. Most top physicists think the universe may be infinite or at least way bigger then the known universe. In the case of the DBZ universe you're probably right since Toriyama said he wanted to make it small.
Wow really. Either of the Saiyans solo.
@katmic: It's a classic shonen series with some of the most interesting characters in manga & anime. You should at least give it a shot it's younger then DBZ and i'm sure you have see that.
