Rust Tyranno is a boss in Chrono Trigger. Appearing in Giant's Claw during the Middle Ages, he guards the Rainbow Shell in the bowels of the cave and is believed to be the fossilized incarnation of Black Tyranno. Due to its extreme mass, Ayla's Boulder Toss and Tail Spin are ineffective against it.
