For the mech in the Sonic Boom comic series, see Big Boy (Sonic Boom).

Rotatatron (ビッグボーイ Biggu Bōi?, lit. "Big Boy"), also known as the "Big Boy" by Doctor Eggman, is a giant robot and the boss of Tropical Resort in the Wii version of Sonic Colors. On Planet Wisp, this boss is shown to have an upgraded counterpart, Refreshinator.


Sonic Colors

After Sonic discovers Eggman is capturing Wisps for his own evil deeds, Eggman unleashes Rotatatron to stop Sonic, but the boss is ultimately demolished. When destroyed, a part of Rotatatron's arm becomes lodged in a part of Dr. Eggman's Incredible Interstellar Amusement Park; and in the end of the story, the arm causes Eggman's giant mind control cannon to backfire.

In Mario & Sonic at the Sochi 2014 Olympic Winter Games, Rotatatron appears as a boss incorporated into the routine in Sonic's Figure Skating Spectacular Dream Event, which is set in a ice rink setting similar to Tropical Resort. During this event, each of the four characters participating in the event must near Rotatatron and carefully time a jump in order to hit its eye. This cycle will then repeat, except this time, Rotatatron shoots red shurikens at the player(s). After enough hits have been dealt, the four characters skate out into the center of the rink. Once in position, the player(s) must spin in order to perform the Final Color Blaster with the aid of the Wisps collected of the course of the event, and deal Rotatatron the final blow.


Boss guide

This boss fight is rather simple, as he only takes three hits to defeat, and attacks by clamping his hands on the circular arena. The weak point of the giant contraption is its large yellow eye located at the center of its body, which can be hit by a Homing Attack, when the eye is fully open. The player will need to jump onto the moving platforms to get closer to the eye. One platform has a capsule containing a Cyan Wisp which can be used to attack either his eye or his arms to deal double damage. If the Cyan Laser attacks Rotatatron's arms, then the laser runs through the arms like an electric current and strikes the eye. After the eye is hit three times by a Homing Attack (or a Homing Attack and Cyan Laser), the robot is destroyed, showering Sonic with Rings, and then the player is ranked. Throughout the fight, Rotatatron will launch red energy discs at Sonic.

  • Rotatatron is the name of the boss according to the Sonic Colors Prima Guide and Vivid Sound X Hybrid Colors: Sonic Colors Original Soundtrack. In-game, however, Eggman calls it the "Big Boy", probably in reference to its Japanese name.
  • Despite being replaced with Globotron in the Nintendo DS version of Sonic Colors, Rotatatron makes a cameo in the second Act of Tropical Resort on the Nintendo DS version as the ferris wheel that chases Sonic towards the end of the Act.
  • One of the samples used in the music that plays during the battle against Rotatatron is also used in the music that plays when fighting Egg Wizard in Sonic Rush Adventure.
