Pick a color, a emotion, a oath, powers, weaknesses, and even a symbol or an origin sttory if you want! For example, mine is:
Color/Name: Platinum Lanterns Emotion: Peace
Origin: Some members of the Green, Blue and Compassion Lantern Corps along with a Guardian from the Blue and Green Corps, came together once to create a new corps to help maintain order and justice. By combining the colors of Green, Blue and Indigo and the emotions of Will, Hope and Compassion, they discovered the Platinum power of Peace. After finding the element, making a battery and forging rings, this new corps was made and remains an important friend and ally to the three corps that came together to create it.
Oath: When Hope burns bright through blackest night,
No evil escapes my Will's sight,
These combined with Compassion's might,
Makes Peace...Platinum's light!
Powers: A Platinum Lantern ring has all the same powers of Blue, Green and Indigo rings but is much, MUCH stronger due to it's three components.
Weaknesses: Platinum/Peace has no large weak points since the three other elements/emotions that create it support and compliment each other so well but it is very slightly weak to Rage and Greed.
Symbol: (ignore the PL, stands for Platinum Lantern, is not part of the symbol)
