fmab is the 日本漫画 faithful version of fma. The original 日本动漫 went off on it's own course around the 秒 season and made up it's own story. FMAB is the 日本漫画 driven version
Think 你 might be referring to FMAB which stands for Fullmetal Alchemist Brotherhood and that would be the 09 version of the FMA 日本动漫 which is much closer to the 日本漫画 compared to original version of the series.
