Here's a funny thing I came up with.. What if Leo's hammer was made up of Copper... As we sort of know... It seems that Leo and Taurus seem to be close and might even think of each other as brothers from different constellations... But hear me out... What if we made them bounce off each other even more. As we both might know, Taurus possibly has lightning powers and I have made him be with a lightning axe as his personal weapon... If Leo's hammer (Ayy-Imma-Ninja's design) were to be made out of copper, it would being their dynamic even closer! Why? Well... Copper is known as a conductive for electricity, managing the electricity and letting it pass through with ease! Same with Silve and Gold.
Imagine... Taurus is farther away from the enemy and Leo is more closer, Taurus aims his lightning bolt at Leo's hammer, to which the hammer then conducts that energy and powers the hammer up and with Leo's next final strike.... BOOM! The lightning combined with Leo's fire from the hammer, takes the enemy down with ease! Basically Taurus' lightning would power up Leo's hammer for when the enemy is more weakened!
They would slay working together on missions honestly and would probably also train together too!! :3
