The Space Wedding is a wedding that takes place in the distant future. It is located in space and was first seen in the episode "Graybles 1000+." The wedding is platformed over a rose-diamond ship and with numerous alien ships surrounding it as security. The wedding includes Space Wedding People hosting and attending it.
In "Graybles 1000+" Cuber tries to get a better look at the wedding by bringing his ship closer to the event. By doing so, he accidentally breaks the bride's space helmet causing her to die and float away into the infinite space. The Space Wedding People retaliate against Cuber for ruining their wedding by chasing after him with their ships.
