A Gem Destabilizer is a modern type of Gem weapon used amongst Gemkind.
Description[]
While specific details among Destabilizers can be altered, the overall concept is an arrowhead-shaped tuning fork. Modifications can be used to alter the appearance of a Destabilizer or to change its function.
Their main function is to poof Gems who step out of line, considered as an upgrade to Rejuvenators. Just like said weapon, any Gem struck with the item is instantly poofed. If modified, it can be powerful enough to alter the sheer anatomy of a Gem.
History[]
in My Little Universe: Season 2, Melanite used one of these weapons against Fulgurite.
In My Little Universe: Season 3, similar weapons were used by Time Jumper against the Crystal Gems to make short work of all of them.
A particularly modified one was seen in My Little Universe: Season 8, created by White Diamond and used on herself to become more powerful and far "better" than her subjects and peers.
