Angela is a villainess from the comic book series Spawn.
She is an angel who acts opposite Spawn as a bounty hunter working under the auspices of Heaven. She attempted to kill Spawn upon their first meeting, but he managed to defeat her despite her significantly greater experience.
When he later came to her aid during her trial in Heaven- ironically, he was there to testify that she had permission to attempt to kill him; when they were temporarily trapped in a pocket dimension, Spawn's instinctive restructuring of reality to allow them to return erased Angela's 'permit' to use her weapons against him-, they started a romantic relationship while returning to Earth. Angela was killed during the battle with Malebolgia in Spawn #100.
In 2013, the rights of the character where purchased by Marvel and a new version of Angela was introduced at the end of the Age of Ultron storyline she was eventually revealed to be one of Thor's siblings.
