Antonio, Antonio 2, and Kantor are a species of enemies. These enemies resemble armored bulls with large forward-pointing horns coming out of their shoulders. All three variants are palette swaps of each other, with hugely varying levels of strength and are fought in different locations in the game. This monster line is and includes two bosses. Only Kantor can be encountered more than once per game file, and even then only for a limited time in a very specific area of the game.
