Mecha Sonic
From Sonic Retro
The name Mecha Sonic is sometimes used interchangeably with Metal Sonic, though such a mix-up involves (at the least) two different personae of the character, most would say there are two separate characters involved. His Sonic the Hedgehog 2 (both versions) incarnation is often referred to as Silver Sonic. This boss is also occasionally referred to as Bionic Sonic, a name popularized by Andrusi, who found it on a card in a pack of Sonic the Hedgehog bubble gum. In the Sonic the Hedgehog Archie Comic issue #39, Sonic is dubbed "Mecha Sonic" when he's captured by Nack and roboticized by Dr. Robotnik.
Sonic 2
Game Gear Version
The first appearance of Mecha Sonic is the metallic robot that Sonic fights in Scrambled Egg Zone on the 8-bit version of Sonic the Hedgehog 2. Once defeated, Mecha Sonic releases the sixth and final Chaos Emerald.
This version of the robot is an ideal imitation of Sonic, mimicking all of his abilities, although strangely Mecha Sonic has a spin dash attack and Sonic does not in that game. When jumping Sonic and Mecha Sonic bounce off each other, making for an fast and hectic battle. Mecha Sonic is also equipped with a sharp scissors-type object, which sometimes protrudes from its torso when standing still.
Genesis Version
The robot that appears in Death Egg Zone on the 16-bit version of Sonic the Hedgehog 2 for the Sega Genesis has three types of movement:
- Run in a direction, slide and turn around, then come back to start of movement
- Curl up into a ball and roll across the screen (similar to Sonic's spindash)
- Curl up into a ball, then jump across the screen
- At some point, needles are shot out during the jump.
Sonic 3
The robot Sonic in Sonic the Hedgehog 3 and Sonic & Knuckles is usually referred to as Mecha Sonic also.
During the encounter in Sonic 3 Mecha Sonic is redish-gold and shoots 3 yellow energy balls and does a air to ground spin attack. After a while, he reverts to his blue pallette and absorbs energy from the Master Emerald. He needs to be attacked 8 times before being destroyed.
In Sonic & Knuckles there are four different encounters with Mecha Sonic. They all take place in Sky Sanctuary Zone. He first appears with a ball and chain weapon similar to the one Robotnik uses in the first Sonic the Hedgehog. Later he appears with 8 bubble-like shields similar to a boss battle in Sonic 2 on the third act of Metropolis Zone. The next encounter is similar to the battle with him in the Death Egg in Sonic 2 except for a new backwards dash attack. If playing as Knuckles there is a fourth battle. Mecha Sonic will go super by absorbing power from the Master Emerald. During this battle he dashes back and forth occasionally diving downward or shooting glowing orbs. He occasionally has to recharge his power by landing on the Master Emerald, this leaves him vulnerable to attack.
