Johnny 99 is an Amerindian Shaman Shadowrunner. He started his career running with Bull. He was trapped with Bull inside Chicago during the events of Bug City. He made a deal with Harlequin to get Bull and his family out of the Containment Zone, and sacrificed himself to slow the approach of the horrors.
- Bull and Johnny 99's deal with Harlequin seems to have been a similar run as seen in the adventure Harlequin's Back.
- In Worlds Without End it is said that an anonymous runner died while trying to even out the mana spike. That runner was probably Johnny 99.
