Abilities: As an empath, Mantis can read the emotions of others while touching them. She can also influence and alter their emotions, "to some extent," in her words.

Power scale: 1. Mantis' powers are quite potent. She was able to make Ego, an ancient and powerful Celestial, sleep against his will in "Guardians of the Galaxy 2." She was also instrumental in the near-defeat of Thanos in "Infinity War." But neither would have been possible without the help of other characters: In the former case, Drax carried her away from danger and saved her life; in the latter, Doctor Strange put her in place to subdue Thanos. Her skill set is extremely specific and, when it comes to most situations, not very useful.
