Spooky

Spooky is a virus in the Mega Man Battle Network series. This virus remains stationary on its panel, but teleports to another one if the player goes to the same row as the virus. After a couple of seconds of standing idly or teleporting away, Spooky will disappear and after a second will reappear on the panel in front of the player (any side) and attack by licking. This virus can also heal itself. Stronger variants teleport away faster, leaving a smaller window of opportunity for attack, and also recover more health and more often.
