Rah-Rah-Robot

The Rah-Rah-Robot is a giant robot that is invented by Dr. Sarah Bellum that was intended for cheerleading to cheer for Jyoti and Tim's outdoor volleyball team, as seen in a The Magic School Bus Rides Again episode, Ralphie Strikes a Nerve.

It was used by Arnold Perlstein, Carlos Ramon, Wanda Li, Ralphie Tennelli, Dorothy Ann Rourke and Keesha Franklin.

In When the Cold Breeze Blows Away, it is upgraded for combat usage by Sarah Bellum and Ruby Ramirez, replacing pom-poms with plasma cannons and machine guns.

It is used to rescue Jyoti and Tim and capture the Dardanelles Robot, and is called by Polina Petrov as Black Wing.
