The main feature of Scaler is the ability for Bobby to transform into five different types of mutant lizards, each one having its own advantages depending on the environment.

Scaler has the ability to ride upon long tube-like pathways that charge his electrical bombs, rendering him ready for combat as soon as he departs from the tubes.

Lizard-loving animal activist Bobby "Scaler" Jenkins discovers five extra-dimensional humanoid reptilian creatures - the leader, Looger, and his henchmen Jazz, Rhombus, Bootcamp, and Turbine - have disguised themselves as humans and intend to conquer the multiverse.

As Scaler and Leon travel the world, they discover that Looger controls a network of unstable portals, intending to create an army of mutant lizards to invade the multiverse.

Years ago, he was a scientist who invented a "portal compass" that transported him to Looger's dimension, where he was imprisoned, tortured, and left amnesiac before eventually escaping.

After defeating Jazz, Rhombus, Turbine, Bootcamp and some of the mutant monsters while rescuing the remaining lizard eggs, Scaler and Leon arrive at Looger's stronghold.
