Yudon

Yudon (ユードーン) is a large stationary enemy in Mega Man 5. It sends two guided missiles after the player. Its head is its weak point, and as it launches missiles, it raises its arms to block shots. If its missiles aren't shot down, it will refrain from raising its arms until one is. Yudon appears in the stages of Napalm Man and Charge Man.

Trivia

 * Yudon is derived from the Japanese word "yuudou", which means guidance.
