Beast X is a creature featured in the 1992 PC Game Ultra Special Tactics Squad Go!
Subtitle: Space Bird
X was a space bird hatched from a meteor-like egg after being shot with the 'Silver Arrow' weapon that terrorized the city and fought and even more evolved Buildgamera. It is considered to be the most powerful kaiju in the game. It's wings are razor sharp and cut through anything and it has an ultimate attack called the 'Black Spark'. This attack is of a fireball-like object being released from the sides of it's head that acts like a giant microwave: it releases magnetic waves and extreme heat that melts anyone or anything even close to it. This monster does not have a weak point but was defeated by Re-Buildgamera after which it went back into hibernation again.
