Caulder

Caulder is the main antagonist of Days of Ruin.

History
In Dr. Caulder's youth, cloning technology has advanced a lot, but wasn't used for ethical reasons. Caulder threw ethics aside and made multiple clones and performed inhumane experiments on them, which caused the clones to rebel and have a bloody war. In the end only one clone remained, and that was the Caulder that became the Leader of Intelligent Defense Systems. Caulder then took the name of his creator created four clones of him as his children, Tabitha, Penny, Cyrus, and Isabella, and supplied Lazuria and Rubinelle with weapons of mass-destruction. After the Meteor strikes, Isabella was separated and joined 12th Battalion, in the midst of a battle between The Beast's Raiders and Brenner's Wolves. After this Caulder supplied the beast after his raiders were destroyed, but after his final defeat, Caulder kills him. Caulder is then seen supplying Lazurian Army, but General Forsythe refuses to use them. After the defeat of the NRA, Caulder sends his kids in The Great Owl to destroy 12th Battalion and take Isabella back. After Penny's defeat, Caulder reveals that Isabella is his clone child which turns public opinion against her, and she defects briefly and joins caulder. After Tabitha's defeat, Caulder decides his children are useless, and orders Penny to kill herself and Isabella and the other passengers of The Great Owl by crashing it, but Isabella convinces her otherwise, and Isabella and Penny join with 12th Battalion, Caulder then forces Cyrus to drink poison, and while he's dying he defects and tells 12th Battalion where the cure to the Creeper is, but dies shortly afterwards. Caulder stays at The Nest a giant factory-weapon. During the battle he tells about him being clones. He is killed in the destruction of The Nest.

Trivia

 * He was removed from multi-player in the US version before the game even came out, thus banned from competitive gameplay.
 * He is the one of the only 2 COs who does not have a CO Power, alongside with Forsythe. This is due to the fact that his CO ability is extremely impressive (in comparison to the other COs' abilities), therefore giving him a CO Power would be considered rather unfair.
 * He is the only CO in any Advance Wars game that heals 5 HP, alongside with Andy.
 * He is the only character to have died immediately as a result of the end of the battle.
