A Lucubra has a green and grey gelatinous body with red teeth like markings on its face. It resembles some kind of lizard. They use tentacles to feed off their victim's thoughts and to communicate with others. Once a person has been fed upon, the Lucubra can send telepathic commands to them.
The Lucubra appear to range in size, one being as large as a dog, while another was several times larger than a human.
Powers and Abilities
A Lucubra has the ability to feed on the thoughts of humans. 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 its obedient servant, evident by the turquoise eyes, which it is implied it can control from other dimensions.
Lucubra are strong enough to knock one of the Forever Knights away with little effort.
Lucubra can fire a powerful laser beam from their face and climb walls.
A Lucubra can't take over beings if their cranium is protected by certain types of materials like iron.
The Lucubra can be contained through magic.
