This is the database from Mega Man Zero 4. Unlike the Mega Man Zero 3 database, all enemies are listed, and the data is obtained by defeating enemies or meeting people. It's divided in four parts: Boss (16), Enemy A (8, sub-bosses), Enemy B (56, enemies) and Other (16, characters). Some names in the English database where compacted and shortened. The most reduced names has their complete ones in parentheses. Typos and shortened words like "undrgrnd" (underground) and "w/" (with) were kept.
