There are 128 monster entries in the PS (Origins) bestiary, and 169 and 170 for the GBA and PSP bestiaries respectively. The following sections list the entries numerically as to how they are listed in the game's official bestiary. Bosses are marked with a ☆.
The bestiary in the Dawn of Souls includes many new enemies not found in the Origins version. In the 20th Anniversary version, two more new enemies were added; one of which is Deumion who has no entry, however.
