Shenlong

Shenlong is the dragon called from the Earth dragonballs, both from Kami's set and Dende's. He is instrumental in the entire series in reviving people and cleaning up messes, and at the end of GT disappears with Goku to let the Earthlings fend for themselves, as he is tired of his power being abused. He appears gruff and is extremely powerful, but Bulma is able to frazzle him on each and every single occasion. A very impressive creature overall.
