Blood types in the Street Fighter series

[Kakariko Kid]

In character profiles in the Street Fighter series, blood types are listed along with statistics such as height and weight.
Ketsueki-gata, or ABO blood types, are supposedly predictive of personality traits, temperament and compatability with others, made popular in the 1970s by author Masahiro Nomi.
