Mercy has claimed to be an actual angel, but it seems more likely that this is not true. Although she may see herself as an angel, the most likely explanation for her origin is that she is a regular human who gained powers.
Mercy has also claimed to be an extraterrestrial alien. Specifically, she said she was a missionary from another planet.
