Lapis Lazuli

Lapis Lazuli is a member of the Crystal Gems that made her debut in "Mirror Gem". During her alignment with

the Gem Homeworld, Lapis was imprisoned within a magical mirror amidst the Rebellion for thousands of years until she eventually convinced Steven to free her. She returned to Homeworld, only to be forced back to Earth by Peridot and Jasper. She fused with Jasper into Malachite to imprison and take her anger out on her, only to later unfuse and decide she has no other choice but to live on Earth, due to trapping a highly-regarded Quartz soldier. Lapis lived at the Barn with the newly reformed Peridot until the threat of another war became a reality. She left Earth and had taken the Barn with her to the Moon. Steven finds her in "Can't Go Back" and convinces her to come back, but after he has another vision of the Diamonds, Lapis decides to leave the Moon. However, in "Reunited", she returns to Earth to fight against the Diamonds, becoming a Crystal Gem in the process. She was poofed by Yellow Diamond.
