Sparky

Sparky, or Shakey as it is known in Mega Man Battle Network 5, known as Yura (ユラ) in Japan, is a virus from the Mega Man Battle Network series. This virus zigzags down the field at super speeds, so it is incredibly hard to target. When they encounter an obstacle in the middle row, they circle around it a couple of times before zigzagging again. They damage the target upon contact. Variants move faster and idle less as they level up.
