All figments are immortal, healing fast, but not instantly. The Seer, Psychic, Scholar, Shifter, and Furnace all have human tier intelligence and can communicate. The Seer never talks more than the bare minimum, although they have concerningly high intelligence. The Furnace is about as intelligent and mature as a 8 year old. Each of them has their own weaknesses and strengths. The Seer can see and hear everywhere at once without issue, along with having higher speed than an airplane. They permanently know your location, including large distances and physical barriers. On the other hand, they sleep 20 hours a day, unable to detect much in that state. They also have the physical strength and durability of a wet paper towel.
The Psychic can control you directly if you look at them, and can confuse or weaken you if they can see you, but you can't see them. On the other hand, their eyesight and hearing is quite poor.
The Scholar can rewind time on an object up to 30 seconds, including living things and broken objects, effectively making them a high powered healer and immune to recently destroyed or locked doorways. They are also the only one who doesn't need rest. They are permanently wearing a hazmat suit. They are absolutely paranoid about "contamination" and will flip out and panic if their suit is damaged.
The Furnace is visually more of an android. They have powers over temperature, the solid/liquid/gas state of things, and have extreme durability and physical strength. On the other hand, they are terrified of fire and rather slow.
Lastly, there's the Shifter. They can shapeshift and change form on a whim, along with being pretty much immune to injury due to regenerating any damage in seconds. On the other hand, they have zero sense of stealth and are fairly reluctant and regretful about killing people. They are also fairly gullible.
Not part of the group, the Raven. The singular figment that isn't either hostile or volatile. They can teleport, enter and exit the last city at will, and are obsessed with anything reflective. They sell unnatural artefacts, taking chrome or mirrors as currency. They don't really care about anyone unless they have something to offer.
