Onyankopon: zodiac sign and birth chart
Onyankopon is a Leo, born on August 2. Canon gives no real-world year, so his Moon and the rest of the chart are NEBO's take. Leo fits the warm one who makes newcomers feel like part of the team. Aquarius fits the outsider who sees the situation with a clear head.

NEBO's take
Canon says Leo. Our model says Aquarius.
We ran Onyankopon through the same model that matches people to characters in the app, and looked at which chart gets him most often. It reads him as Aquarius first: Mars too, with Libra Moon and Rising. Open-minded, friendly and a bit of an outsider, fair to everyone.
