What is Demon Blood Sword?
History of Demon Blood Sword
The blade itself has shown an immense amount of strength and durability. Finn used it to stab and lift the Evil Monster (who should have weighed at least a couple tons) off the ground and toss the monster into a pit, and the sword did not bend in the slightest. The sword has also been shown to easily resist energy beams Marceline creates when in her 'blood mist form', despite the beams' ability to destroy or transform near anything they hit. The sword has also been shown to be fireproof, as Flame Princess was able to wield it without consequence. This durability may have been attributed to the fact that it is made of demon blood.
