During their fusion, she stands in the middle, being the connection point to all the other Rubies. They are seen playing along with her when she pokes fun at Pearl for being talkative, kicks some dirt to demonstrate her animosity towards the Earth, or gives the Crystal Gems the silly nickname Crystal Germs. Upon learning that she was assigned to the Earth mission, the Ruby fusion demands that Peridot tell her where Jasper is. After Steven opens the airlock, Sardonyx forces the Ruby fusion to un-fuse and the Rubies are sucked out into the vacuum of space. With her disguise revealed, Doc orders the other Rubies to assemble and they fuse to fight the Crystal Gems. During the baseball game in "Hit the Diamond", she befriended the Crystal Gem Ruby thinking she was a Homeworld Gem but was later shown to dislike her when she and Sapphire fused and exposed their identities as Gems.
