Liquid metal wins solo battle V HellFire. Against hell fire is easy. Liquid metal can smother hell fire, because fire needs oxygen to burn. Once covered up, the fire would die out. Done! Liquid metal wins.
Liquid metal wins solo battle V Ice. Against ice a bit trickier, but liquid metal can still cover the ice, once it melts its gone. Even if the ice solidifies the metal, the metal is stronger and heavier than ice and can crush it. Done! Liquid metal wins.
