Kanzenshuu

The name "Daitouden" ("大闘伝") is derived from the word "Butouden" ("武闘伝"). "Butouden" is taken from the names of Dragon Ball games that use that word (the Super Butouden games for the Super Famicom/Super NES and the Sega Saturn exclusive Shin Butouden). The name ("Daitouden") replaces the "bu" ("武", meaning military, martial) kanji with the "dai" ("大", meaning big, large, great) kanji, forming the name "Daitouden". "Daitouden" literally means "great fighting legend" or "great fighting story".

It's comparable to the origin of the name "Nintendo" ("任天堂"), which is derived from the phrase "Leave luck to heaven" (「運を天に任せる。」, Un o ten ni makaseru). In a literal sense, "Nintendo" means "Temple of Heaven Under Duty".
