Ghost in the Shell (all seasons, even if they had different names)
Dragonball Z (you either wanted to be Goku or Vegeta, simple as is)
Claymore (short, and holy fuck did it go hard at times)
Fullmetal Alchemist (even if it went off-trial, I still loved it!)
Fullmetal Alchemist: Brotherhood (a more-true to the manga release - also dope!)
Samurai Champloo (they had Dutch-speaking characters! Also made me learn a bunch of Dutch history and how we used to trade with the Japanese since 1609 because of an Englishman called William Adams (Miura Anjin)!)
Alfred J. Kwak (Kwak the Duck - あひるのクワック- my childhood favorite)
Ox Tales/Boes (a childhood classic)
Dommel/Wowser/Bigger and Better: Dommel & Ron (another childhood classic)
In no particular order (maybe)
