Wander Over Yonder(2013)

The adventures of Wander, an eternally-optimistic intergalactic traveler and constant do-gooder, and his quick-tempered but loyal steed and best friend, Sylvia. The friendliest face in outer space, Wander journeys across the galaxies to spread good cheer and to help anyone he can — much to his overly pragmatic stallion’s chagrin. Their fun-loving escapades often lead them to clash with the evil villain Lord Hater and his army of Watchdogs, who travel from planet to planet trying to make hate the order of the day. Together, the best friends travel through the cosmos, happening upon one freewheeling adventure after another and making new friends and foes.
