Commanding Officers in Advance Wars: Days of Ruin

This is a list of commanding officers from the Advance Wars: Days of Ruin video game, an installment of the Advance Wars series of video games. All characters mentioned here appear only in Days of Ruin.

COs in the Advance Wars series often give their forces advantages and disadvantages. In Days of Ruin, the CO has the ability to travel with a single unit, temporarily establishing a CO zone that empowers all units within range (including the unit the CO is in) until the unit is either destroyed or the unit the CO is traveling with returns to their respective HQ. These CO zones increase in range as the COs power bar is filled. With the exception of two COs, all COs have the ability to activate CO powers, which usually last for one turn and provide more significant benefits, in addition to spreading the effects of the CO Zone throughout the entire battlefield.

12th Battalion

 * Also known as the 12th Independent Legion in other game versions.

Will
Will (Ed in the European and Japanese versions) is the main protagonist of Days of Ruin. He is introduced at the beginning of the game as a young cadet from the Rubinelle Military Academy. During the catastrophic meteor strike that devastates the world in Days of Ruin, Will is trapped in the Academy's mess hall. He survives on meager rations while he digs a way out of the mess hall, and then meets the 12th Battalion of Rubinelle's former military, commanded by Brenner and Lin after they defeat a roving band of raiders led by The Beast. Will joins Brenner in his mission to rescue as many of the survivors as possible, quickly taking up the cause and setting the stage for the campaign plot.

Brenner (O'Brien in the European version, Brown in the Japanese version) was a competent military commander before the meteor strikes. He has dedicated himself to rescuing any survivors and defending them from the bands of scavengers that have sprung up as a result of the impact. He is later killed while trying to cover the escape of the 12th Battalion and Lazurian POWs; Greyfield uses one of Caulder's weapons to destroy the abandoned city Brenner had hidden in. His father fought against Forsythe in the war before the meteor strikes, and Forsythe describes him as a man of honor, letting the Lazurians bury their dead, and not using any cheap tricks.

He wants to destroy the Lazurian Army and rule the world as King Greyfield the Mighty. He is later shot and killed by Lin after failing to launch a wave of Caulder Missiles that would have destroyed the 12th Battalion.

He seeks a world where he is free to carry out his terrible experiments, and is the creator of the Creeper virus that plagues the survivors of the meteor strikes.

Non-Playable COs/Characters
Unique to Days of Ruin are non-playable characters which are only seen in the game's campaign. These characters cannot be unlocked for play outside of the campaign, and have no CO zones or CO powers. Days of Ruin is the first game in the Advance Wars series to include non-playable characters.

The Beast
Always referring to himself as "The Beast" (Drakov in the European version), this rogue CO leads a small group of outlaws seeking to take advantage of the downfall of the two main world superpowers, Rubinelle and Lazuria. He was formerly a sergeant of the Rubinelle Army, but was expelled for his violent behavior. He is encountered as the enemy in several of the early missions of the game. He is later killed by medicine given to him by Caulder.

Mayor of Freehaven
Rescued by Brenner after the meteors struck, he is the mayor of the small village of Freehaven. He is a cowardly man who pretends to care about his people, but looks out only for his own well-being. He also makes several attempts to secure himself a higher position of power among the civilians of the 12th Battalion. Fittingly, he dies by his own selfishness, using the only sample of the vaccine for the Creeper on himself; the vaccine turns out to be poison, and kills him.

Dr. Morris
Formerly a medical researcher, Dr. Morris (Dr. Moritz in Europe) is the elected representative of the survivors of the city of New Wolfington, and later travels with Brenner's Wolves. He is an optimistic man with a knack for (rather terrible) puns, and often makes jokes even in dire circumstances. He is somewhat of an authority on the deadly Creeper virus, and is able to develop a temporary vaccince against the virus's mutated form later on.

Davis
Davis (Cole in the European Version) is a commander of the New Rubinelle Army who is rescued by the 12th Battalion. He is often belittled and ignored by the other New Rubinelle Army COs. Later on, he joins the Fanatic's cult after being infected by the Creeper virus.

Fanatic
The leader of a cult which worships a mysterious entity known as The Worm. He offers a magical cure for the Creeper to all who worship. He believes he is helping the people by giving them hope, albeit false hope, to help them survive. The Worm itself is later revealed to be a mere earthworm.

Cyrus
Cyrus is the son of Caulder and a commander of Intelligent Defense Systems. He has doubts about his father's decisions and work ethics, as he sees it as cruel to kill people meaninglessly. He later betrays Caulder and allows the 12th Battalion to secretly board the massive IDS bomber known as the Great Owl (Pulsatrix in other versions). The battle on board the aircraft inflicts irreparable damage to its vital systems and causes it to crash. Consequently, Cyrus is killed by Caulder for his actions.
