The Double-headed whip is a Mogadorian item and a weapon of choice of Setrákus Ra. The whip has two ends and when used it explodes with orange flames.

Upon contact with the target, the skin starts to blister and turn black and starts to form black rock which is heavy and can slow the target down. The rock spreads over the body until the target is trapped in a crystalised rock form.

It is first seen at the Battle of Dulce used on Six, she is helpless and unable to escape as her legacies have been removed. Six is able to escape from the rock once her strength has returned.
