Grindor

Grindor was a clone of Blackout that was killed by Kakamu.

History
Grindor was created by the Architect as part of some experiment. Whatever the experiment was, it apparently failed, so Grindor ended up joining the Brotherhood of Makuta. When Blackout was fighting Kakamu (who was inhabiting Trantoshen's body at the time) on the Matoran in a Black Suit's homeworld, Blackout summoned Grindor and Starscream through a portal to help him. Kakamu mounted Masaharu as a steed and charged at Grindor while Masaharu himself launched his tongue at him, but Grindor dodged them both and proceeded to charge after them himself. However, Grindor was soon stopped in his tracks by Kakamu, who electrocuted him to death.
