The Gangrene Gang was an unorganized mob army of CPR. It did not last long, but it did see a great battle.
The Gangrene Gang officially came to in late November. This army was believed to have several gang leaders as you can see them a lot. The army did not take part in any battle until December 12th, 2017. The army was apart of the first battle of the RPF-RPM War. During this battle Gangrene was tiny. They disbanded after the battle sometime the next day or two. It is now a mystery of what it is.
