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.
Powers and AbilitiesLucubra 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.
WeaknessesThe Lucubra can take over beings but if their cranium is protected by the right type of metals or something similar in hardness and toughness, it cannot control them nor can its tentacles reach their victim. It also cannot pass through magic seals.
- If you look closely, the Lucubra's body and tentacles are similar to AmpFibian's and the temporal creature in episode Paradox and Wildmutt's body.
- Gwen said the Lucubra is an insect when compared to the power of Diagon. Additionally, Azmuth says Lucubras are nothing like Diagon.
- The Lucubra has many features that a traditional demon has in general demonology and mythology:
- The Lucubra is very durable, being able to take hits from the Forever Knight's weapons, Gwen's attacks, Kevin's attacks and even NRG's attacks with no visible physical damage at all.
- The Lucubra can be contained by magic.
