The Omega

The Omega are regarded as the most powerful Squad in terms of brute force. Their ruthless tactics and destructive capabilities make them a scary bunch, and are known for the most collateral damage. Due to the lack of knowledge of coding/wiki creating, there are no spoiler warnings besides the one I am giving you right now. Spoilers. Continue at your own risk. This is information taken from the end plan. Changes may occur.

The Omega is referred to as the Squadron of Destroyers, due to their ruthlessness and lack of care for collateral damage. They are the most looked down upon by the governments due to them being unwilling to listen to anyone other than themselves. Omega has betrayed the squads before during the Omega Arc, and because of that people do not trust the Squadron.

Leaders
Leaders are the highest rank in the Omega. Omega leaders lead their squad proudly. They are to attend squad meetings, form plans for the future, and watch over their squad. Omega Leaders are to be skilled, quick on both their feet and mind, powerful, and most of all work well in tough situations. It's just a plus that most of them are Ruthless. Agents can only be commander once, and after that retire or go back to their previous rank. New leaders are only chosen when the old one steps down or dies.

Second Leader: Hudson "Atlas" Hasinashi, the Assassin's Compass

Third Leader: Mediko Dridean, Ryezures of Kindness

Fourth Leader: Laurence "Executor" Lane, the Executor of Justice

Right Hands
Second in commands who have almost as much power as the commander, with a few limitations. Right Hands usually keep watch of the squad, maintaining balances and assisting the commander. They are not required to attend meetings, but are recommended to do so. If something were to happen to a commander, the current Right Hand is to take command. If neither are capable of leading, the next most capable person will take command. Right Hands have to specifically chosen by the Commander. Mediko so far is the only right hand to have served under two leaders.

Staff
Like the others, the Omega does have a staff. The staff's job is to support the agents with thing like Medical, engineering, guards, etc. Despite the staff, they are always led by a Agent. They handle the smaller things, while the Agents work on fighting.

Trivia

 * Both Magician and Alchemist are twins, with their names being almost identical. They are the memes of Omega, as only Mediko and a few of the other agents are able to tell the two apart.
 * Omega is the 24th letter of the Greek alphabet.
