Wilykit like Lion-O

Lion-O is the son of Claudus, and is the leader and hereditary "Lord of the ThunderCats". His adventures are shown from childhood to adulthood on Third Earth and New Thundera, together with his friends and followers, the ThunderCats. The blade of the Sword of Omens can extend or retract, being in the form of a dagger when resting, and a full-length broadsword form when at full strength and power. The blade itself isn't not indestructible, but shown to be extremely strong, durable, and razor-sharp. It is able to slice through hardened materials such as steel and solid stone with relative ease.
