There is a form of vibranium in the savage land called antimetal that emits vibrations instead of absorbing them. In a way it's a form anti-vibranium. It can liquify any metal depending on the ammount you have, the frequencies change depending on the density until a wavelengh that can destroy even adamantium or vibranium can be found.
