Oberon is the crowned representative of the magical world. His presence tells us that the play should end happily. He sincerely sympathizes with all lovers, whose feelings were cruelly deceived. Oberon embodies some good spirit of family well-being, but he can show his “dark” qualities. A striking proof of this is the episode with Titania. Shakespeare does not explain to us why Oberon enters into battle with her. Perhaps he wants to prove own power or bring a little discipline into the boy's life. In this struggle, Oberon demonstrates unprecedented cruelty, using spells and potions against her. We see in the figure of Oberon the personification of the higher principle, whose motivation remains unknown to us, like his wisdom.
