Shaman King features a world-wide tournament held every 500 years to decide the fate of the world whereas G Gundam's world-wide tournament is held every 4 years to decide who rules Earth. Both of these shows also have a somewhat racist, yet humorous, portrayal of their respective fighters from around the world with the exception of Japan itself.
Both with with how tragic and devastating war is seen through the eyes of children. 0080 shows how war is not a game and only results in death and suffering while Fireflies depicts how hard it is for individuals to survive in a war torn country.
Both Gankutsuou and Gungrave can be viewed as revenge stories. Gankutsuou is based off the classic novel where Edmond Dantes is sent to prison falsely by his best friend and two other individuals . Upon escaping years later, he extracts revenge on them under the guise of a Count. In Gungrave, Brandon Heat is brought back to life by a scientist to pretty much do the same thing as in Gankutsuou. The difference with Gungrave is that it goes back and explores Brandon's past with his best friend Harry, and what made him lead up to this situation.
Shoji Kawamori was involved in the production of both of these anime in some way. The stories are also somewhat similar with both focusing on 2 prototype mechas. 0083 and Plus also have stunning artwork that has been highly regarded since their release in 1990 and 1994 respectively.
Shinichiro Watanabe had significant involvement in the creations of both Cowboy Bebop and Macross Plus. Both have similar character designs and a somewhat similar story as to where the main lead can't seem to avoid their pasts involving two of their friends(ie Guld and Myung in Plus and Julia and Vicious in Bebop) .
Both Darker than Black and Cowboy Bebop are both episodic anime which eventually lead to an overall plot that is tied in with the main character's past in some way(ie Spike and Hei) that are presented in the last few episodes. They also both feature a soundtrack done by Yoko Kanno
Gurren Lagann and Nadesico are both tributes to mecha anime in general albeit with some differences. Gurren Lagann is a tribute to the old super robot shows from the 70s such as Getter Robo and Mazinger while Nadesico is a parody of mecha anime in general with some tribute to mecha anime of all eras.
Both shows take place in a post apocalyptic setting featuring mecha that are of god-like proportions. Both of them also feature psychological aspects and religious symbolism(although it only has meanings in Big O and not Evangelion).
Eureka 7 borrows some elements from Evangelion. Eureka is clearly a tribute/copy of Rei and the Nivash and TheEnd both have "souls" much like the Evangelions.
Gundam X can almost be considered as the anime that influenced several plot aspects of Eureka 7. Garrod and Renton are very similar in the fact that they both join up with a group of individuals on a ship in order to protect a mysterious girl they immediately fall for (ie Eureka and Tiffa).
Same director. Story focuses on how time travel can negatively impact your surroundings, which is similar to how Summer's Wars' plot revolves around the internet being connected to the entire world and how it can impact society if in the wrong hands.
The set-up of both are strikingly similar, so close that RahXephon can be called a rip-off, but it has a more easy to follow story and wraps up the show with one of the best ending episodes you will ever see.
