I just realized that I never actually explained how the team are singularities, so... Guess it's an impromptu:
Worldcanon: Singularity and the rules
When Solaris froze the team after defeating LaPlante, the new God decided to freeze their souls at that exact moment. Solaris first coined this term, but they are referred to as singularities - a fixed point in time. But what does this mean, exactly?
Being a fixed point in time, that means that they don't age, and their bodies don't deteriorate due to age. They're essentially stuck at the age they were at when Solaris froze them.
This also means that the team has an advanced form of healing. When a member gets seriously injured, their body will revert back to the fixed point. This means that any wound will be healed, and the team is unable to die, even by a serious injury.
However, it isn't an instant process, and injuries take time to heal - at the same rate of time as every other being. This means that the team can still be taken out through fights, and requires rest to feel better.
While someone could defeat them in a fight, they are overall only slowing the team down a little, and delaying the inevitable of the team member coming back for them.
So for posterity, here are the rules regarding all of this:
1. A singularity cannot age, cannot grow older, and can heal wounds inflicted on them.
2. A singularity cannot die, even by fatal wounds.
3. If a singularity is injured, healing said injuries take the normal amount of time to heal (a broken leg takes 6-8 weeks, cuts take a few days, etc.).
4. A singularity can be defeated in battle in standard ways, such as knocking them out, causing an injury to make them bleed out, or by exhausting them.
4a. Bleeding out will cause the singularity to pass out, and they will remain out of commission until the lost blood is replenished in the body. This process can be sped up via blood transfusion.
