Right as the battle begins, taunt for TP. Then, proceed to the usual Chain Yanker + Yes Man Kablaam tactic and unleash godhand. Assuming you have some of the strongest punch techniques equipped, 3 unleashes and a Kungfu Tango should do the job.

Remember that each time Shannon gets up and recovers from a pummel (when she gets dizzied), you can use that time to get in another Yes Man Kablaam to refill more TP.
