Spider-Man's Therapist

When Spider-Man was looking for help working through some trauma, Misty Knight called in a favor to Doc Sasquatch. As his protege, Keisha was assigned to have regular meetings with the hero.

God War

While presenting her work to Doc, Keisha was suddenly teleported to Miles' side on the ruins of Mount Olympus. She had been chosen as one of the champions of Anansi, like Miles was, in order to compete in a challenge given to Anansi by Ares. Ares was unhappy that Anansi had taken a champion, betraying a pact between their two pantheons. Keisha was chosen for the first bout and forced to fight Philomelus, demigod of agriculture and patron of husbandry. During the fight Keisha revealed that, like her mentor, she had gamma powered super strength, which one her the first round. Rather than mutual combat, the next round was one of Hercules' twelve labors. Miles convinced the champions to work together, ending the challenge in a draw.

This revealed Anansi's secret plan to fight Ares one on one. According to the rules, if the tournament of champions ended in a draw, than Anansi and Ares had to fight as a tie-breaker. When pressed by his champions, Anansi shared the story of how their feud began over a mortal dressmaker who was so talented Ares felt she needed to be humbled. This brought criticisms of pettiness from Miles, which Ares grew tired of entertaining. As the last surviving Olympian of his generation, he accepted his role as the new Skyfather and moved their tournament to Brooklyn so that Miles had proper stakes.
