Darkskull was once a great king of a rich and beutiful land. But, when the Skeleton Army laid waste to the land, King Garkel, as he was called, was ran over by a skull truck. He amazingly survived, but only his bones were intact. He then joined the Skeleton Army, seeing nothing else to do. After the apparent death of Samukai, Garkel took over the army and gave himself the name 'Darkskull'. He currently rules the underworld of Ninjago, and will most likely raise an attack on Ninjago.
He uses a shield with a skull on it.
Garkel Pics and building instructions coming soon!! :)
