Instead of giving the Green Lantern a roleplay page, I decided to give you or a Sonic character a scenario where you become each of the good Lantern Corps.

Ring Scenario: You have just saved someone using all of your courage and willpower. Suddenly, a green ring floated towards you and let you wear it. The ring chose you to be the Green Lantern of your sector. Do you accept?

Core Scenario: The battle for peace throughout the universe has grown difficult over the years. It becomes harder every day to keep order when there's so many other Corps and countless threats, especially from Mobius/Earth.

The Guardians came together and decided that they should make a being made from pure willpower to be the main defender of the universe.

After they focused all their energy together, you were born from the main Green Power Core.

Now you fight evil everywhere it lurks.

(Here's the Green Lantern oath)

In brightest day, in blackest night

No evil shall escape my sight

Let all those who worship evil's might

Beware my power, Green Lantern's light!

You are now a Green Lantern
