[Name] Creeping Derangea [Source] Advance Wars: Days of Ruin [Symptoms] 
An artificial virus that is revealed to be a failed Bio-Weapon created by Dr. Caulder to test the extent of IDS technology. Due to its inherent flaw of photophobia, creeping derangea is only able to thrive when the sun was effectively blocked out by the vast amounts of dust that were kicked up into the troposphere and stratosphere by the apocalyptic meteor impact events. The Virus is initially only able to infect those under the age of 20 but a new strain is somehow introduced that can infect older hosts over time. Symptoms include headaches, paranoia, and a black diamond on the skin called "the mark". It causes flowers to grow inside a person and break out of the skin. A beautiful, albeit excruciatingly painful, way to die. Its scientific name is Endoflorescens terribilis. It is also known as The Creeper and the Green Thumb.
