Superpowers for trios?

I find it depends on what world/time it plays and how the story is. I also find a balance important – it must not make it almighty and must have unpleasant aspects for the protagonist.

• Anyone who has negative in mind to the prot. suffers burns. The more negative intentions / feelings, the stronger the burns. That’s why he always has to pay attention to who touches him. Ggf burns the person himself.
• The look is like a lunatic – who sees the prot in his eyes loses in it. If you look too long, you lose your mind. But you can only look away with very great willpower. A sunglasses helps little. That’s why the prot must always wear a mask that makes him blind.
• The tattoos awaken to life and can leave the body. For example, tattoos of swords that can be pulled out of the skin. Or tattooed wings that can be detached from the skin and become real.

It could also be skills that complement each other.

• Influence on nature – one can control fire, an earth, an air.
• Influence on time – one can see into the future, one in the past, one can see what happens elsewhere in the present.
• Influence on people – one can read/control thoughts, a feeling, one the soul.

The skills could be associated with a task.

• You can see spirits, feel where someone dies and/or guide souls to death or judge them.
