" Nocturnal by nature, Balthazar thrives in the dark caverns of Inferno. Its wings give it the ability to swoop in on ususpecting enemies to land deadly attacks. "

General information

Balthazar is a flying bat-like creature. It has one leg and two black eyes. What is notable about its stats is that it is the fastest monster in Backyard Monsters. Also, it's a 'Bunker Buster', as it deals 3x damage to bunkered monsters and Champions, and this ability does not need to be researched.

IMPORTANT: (Behavior) When Balthazar are flung into an enemy yard, they will first attack the nearest Champion, then Bunker/Compound/spurtz cannon (assuming they're filled with / shoot monsters) then will fly across the yard attacking monsters until there are no monsters left. They will do this at their own peril, crossing through enemy fire if on the hunt, before ever moving on to any other towers/building you might want them to attack.

This makes their path of attack unpredictable, and hazardous as they are vulnerable to every tower (except laser tower and cannon tower) in the game including Railgun and Aerial Defense Tower attacks and although it has wings and can fly over defense walls, Balthazar can be damaged by land monsters, including Gorgo and Drull and will trigger Booby Traps.
