Venom Mighty Axe

Harnessing the Odinforce within Thor's hammer and the Power Cosmic imbued into the Silver Surfer's board, Venom's ax commanded two of the most powerful forces in Marvel Comics, even before adding the might of Uni-Power.
The original ax was forged using Mjolnir and the Silver Surfer's board, bonded together by Eddie with the power of Captain Universe, so there's almost no way this version was made using the same materials.
