The Electro Axe was a battle axe used by Steppenwolf from the planet Apokolips. Steppenwolf used it in his mission to take back the Mother Boxes on Darkseid's orders. However, it was destroyed by the combined efforts of resurrected Superman and Wonder Woman during Steppenwolf's final battle with the Justice League.
To be added
The Electro Axe is shown to emit a red-hued energy that, when struck against a surface, disperses and spreads continuously. The energy is seen capable of infecting human soldiers, turning their skin a pale grey, while lengthing and sharpening their teeth, seemingly transforming them into the Parademon soldiers of Apokolips. The axe is also nigh-indestructible, as it can go up against Wonder Woman's weaponry, however, when exposed to resurrected Superman's Arctic breath, it became brittle, allowing Wonder Woman to shatter it.
