T-Rex
Uses Frightful Assault, hitting three times. The first time is a bite. The second whip is a longer ranged tail whip that turns T-Rex around. The last hit is a stream of fire breath with the longest range.
Spinax
Uses Cyclone multiple times, breathing streams of wind through the air, and sometimes turning around first.
Elasmo
Uses Elasmo Combo, hitting twice. The first time is a head tackle, and the second time is a spin. The spin has a 50% chance to enrage the opponent, decreasing the range of their attacks, but making them stronger.
Megalo
Uses Null Breath, breathing a large cloud of gas. Opponents who touch the gas are scared, having a random two of their special moves disabled.
Balrog
Uses Turn Punch. He first faces an opponent, then turns around, charges, and faces the opponent again with a ranged punch. He'll do this entire process three times.
Black Mage
Uses Firaga to throw a flaming uppercut, then Thundaga for a rising thunderbolt behind him, then Blizzaga for a blast of chilly air under him that freezes.
