| "That's not what happened at all!"
This article is about something not canon to either the storyline of the TV show, Ninjago: Masters of Spinjitzu, or the LEGO Movie franchise.
There is little to no info about the Obsidian Glaive's creation, other than the fact that it originally belonged to Hibiki before being stolen. It is also revealed to be a dangerous artifact from long ago.
Ronin used the Obsidian Glaive to steal the memories of the Ninja, but Sensei Wu stopped him from completely stealing them, and he escaped with the Glaive. Ronin would also later use the Obsidian Glaive on the Serpentine, making them work for him.
The Obsidian Glaive has the dangerous power to steal and/or alter the memories of its victims. However, its effect can be reverted by either obtaining one of the Obsidian Weapons, or to destroy it.
- It's unknown how the Obsidian Glaive was created.
- Similar to how the other Obsidian Weapons correspond with the Ninja, the Glaive evidently corresponded with Lloyd to some extent, despite never being wielded by him.
