Raichu is one of BrantSteele's simulator co-hosts, along with Chris McLean.
Raichu is the host of Circle and The Challenge. When an All-Stars edition of either simulator is released, Guy the White hosts instead, due to his holy powers being much more powerful than Raichu's electrical powers. Raichu will also briefly appear during Big Brother finales to send the second place houseguest out of the house.
Like Chris, Raichu is never a tribute in the Hunger Games simulator.
