* ''Manga/{{Lady}}'': Protagonist Lynn was more cowardly and temperamental in the manga, and had some unintentional {{Jerkass}} moments. The anime makes her a more curious, wide-eyed and sweet little girl who [[ThePollyanna never stops losing hope]].

** The character of Bobassa is heavily different in both versions of the Millennium World arc. In the manga he is intelligent and very serious [[spoiler:as well as an alternate form of Shadi]], while in the anime he is primarily a comic relief character who is very simple-minded and spends most of his time thinking of his appetite.
** For a dub example, in the original Japanese anime, the computer Kaiba used to hack into Pegasus' database and find Yugi during the Duelist Kingdom arc speaks in a typical MachineMonotone giving very basic responses to Kaiba's orders. The Creator/FourKidsEntertainment dub instead gives it a very human personality, talking like snarky woman who trades quips with Kaiba during the whole sequence.

** ''Anime/YuGiOh'' The character of Bobassa is heavily different in both versions of the Millennium World arc. In the manga he is intelligent and very serious [[spoiler:as well as an alternate form of Shadi]], while in the anime he is primarily a comic relief character who is very simple-minded and spends most of his time thinking of his appetite.

** Fuhrer Bradley is a much more arrogant dick in the 2003 anime than his more AffablyEvil self in the manga. [[spoiler:Possibly because he's Pride in the 2003 anime, rather than Wrath.]]
** Basque Grand in the manga is a ReasonableAuthorityFigure and AFatherToHisMen who shot his own commanding officer to save his men from dying needlessly, and even granted the high priest of Ishval an audience with Fuhrer Bradley in an effort to stop the war. In the 2003 anime, he's a BloodKnight who relished in massacring Ishbalans.

*** Hiroto Honda ws a completely different character compared to his manga counterpart. In the manga, he was a tough guy who was VitriolicBestBuds with Jonouchi, while the original anime series portrayed him as a dorky hall monitor who was obsessed with playing by the rules. His one-sided crush on Miho also gets ramped up to HopelessSuitor status.

*** The character of Bobassa is heavily different in both versions of the Millennium World arc. In the manga he is intelligent and very serious [[spoiler: as well as an alternate form of Shadi]], while in the anime he is primarily a comic relief character who is very simple-minded and spends most of his time thinking of his appetite.
** ''Manga/YuGiOhGX'': The manga adaptation of Jun is far different from his anime counter part. In the anime, he was a hot-headed narcissist who often served as comic relief. In the manga, he's reclusive, calm, and far less egotistical.
