|Artwork of Wood Man from Mega Man 2|
Wood Man's AI follows a simple pattern that he won't stray from. Immediately on starting the fight, he'll throw up a Leaf Shield to reflect most projectiles. Following that, four leaves will rain down onto the Player Character to do damage, and the Leaf Shield will be tossed at the player mid-ways through the leaf rain. Wood Man will then leap towards the player and start the pattern over again. Unlike most bosses, defeating him does not despawn his projectiles: the falling leaves still can harm the player character until they fall from the screen.
Even if the Leaf Shield and the four upwards leaves are negated, four leaves will still appear.
