A Lucubra (pronounced Low-coo-bra) is a demon from another dimension sealed by the first Forever Knight using a spell, as said by Gwen. It has a green and gray gelatinous body with red teeth like markings in its body, resembling some kind of lizard. It uses tentacles to feed on its victim's thoughts and uses them to communicate with others, once a person has been fed upon the Lucubra can send them commands telepathically. They seem to range in sizes, one being as large as a dog, while another was twice as big as a man.
Powers and AbilitiesEdit
A Lucubra has the ability to feed on the thoughts of humans and possibly other species. Gwen states that it feeds on the part of the mind used to pray or meditate until there is nothing left of the victim's mind. The victim then becomes it's obedient servant, evident by the turquoise eyes, which it is implied it can control from other dimensions. Lucubra is also very durable, able to withstand repeated attacks from Ben and Kevin while taking little to no bodily damage. It is also strong enough to knock one of the knights away with little effort, it can fire a powerful laser beam from its face and climb walls.
A Lucubra can't take over beings if their cranium is protected by certain types of materials like metal. It can also be contained through magic.
In Lucubra Unsealed, he mind controls Aggregor.
In Story Of Costin, the lucubras were defeated by Costin in flashback.
