Zogar and his power trident.

Zogar's Trident 2

Zogar uses his trident to burst through a wall.

This weapon was originally owned by Kublai and was given to Zogar to help him fight Thundarr. While this weapon was apparently equal to the Sunsword, it appears that it's power source became exhausted in Zogar's last fight with Thundarr. After which, the trident was destroyed.
