The Omega Sword

The Omega Sword is a very colorful sword that grants immense power. Anybody who holds the sword will feel their muscles become stronger. This effect is thought to be very painful and unpleasant. After this stage, the person holding the sword will then have an immense rage. This will cause them to go out and attack anybody on sight. Though once this rage has passed, the person will not feel anymore pain and will keep their power, which they can now control and use at any time. They can also pick up the sword freely. If they stab somebody with the sword, then that person will almost immediately turn into nothing but dust. If this sword is combined with the 2 other swords, then you can do anything with half of the human race. Either kill them, make them look exactly like you, and many other things.

Defenders Military #37
In Defenders Military #37, King Antoro equips all 3 swords and uses them to turn a majority of the human population of Earth into a similar entity looking like him for revenge after being bullied all his life based on his appearance. Most of the Defenders Military are not affected and soon try to plan a way to reverse all of the people to their normal selves and stop the evil King Antoro and his allies from doing anymore harm to the Earth.
