Billy (virus)

Billy (ビリー) is a virus from the Mega Man Battle Network series. They looks like a ball with eyes, stubby feet, probe-like arms and a lighting bolt protruding out of the back of their head. When in battle, these viruses move around by one panel in random directions. After a set amount of moves, they begin their attack by clenching their need thin arms and releasing a slow moving, homming electric ball, which moves in the air by one panel for a set duration of time. If hit, they cause the player to be paralyzed for a brief moment and stunned for a bit longer. (When stunned, everytime the player moves one panel, their motion is interrupted to deliver a quick shock, dealing 10HP of damage). After a few seconds wandering around after the player, the ball disappears; and upon moving a set amount of squares, the viruses repeat this attack pattern. Stronger variants release faster and more damaging electric balls.
