In the GO game, Kabata Taruhiko and Itsuki Katsumasa have their positions switched on the formation. Also, when you fight them for the second time as a practice match, the SEEDs are kicked out of the team and Miyabino Reiichi is the new captain.
However, even though the SEEDs were supposed to have been kicked out, they were part of the team again in Inazuma Eleven GO Galaxy.
Most of the members' dub names are references to prestigious universities.
In the manga, all of Teikoku's members are SEEDs and Teikoku's coach isn't Kidou Yuuto.
