Menma is the "corrupted" mirror wold counterpart of Naruto. Living in a world created by Obito's Genjutsu. Menma is the opposite of Naruto mentally and physically. He is a talented and genius level ninja that was even capable of killing Jiraiya and leveling Konoha in one blast. Despite all this he is still very ticklish, and in some spots is worse than Naruto.
