Flywheels
- Flywheels is a Decepticon Duocon from the Generation 1 continuity family.

Flywheels tries to keep it together and stay upbeat, he really does, but it's hard when your mind (and often your body) is literally divided in two. A split personality would be trouble enough, but to add injury to illness, Flywheels's two halves are very jealous of each other and basically hate each other's guts. They spend more time fighting one another than the Autobots. It doesn't matter whether they're unified in robot form or not, Flywheels's two halves go right on arguing, which can be disconcerting to others around him, to say the least.

Flywheels first appeared in a brief battle against Ultra Magnus and the Sparkabots. He was knocked out of the air by Ultra Magnus and was captured by the Autobots. As a prisoner, he was soon forced to fight with his captors against a horde of zombie Transformers in Kalis let loose by Flame. Flywheels disobeyed Ultra Magnus's order not to open fire on the zombots. City of Fear! While engaged in the fighting with the zombots, Ultra Magnus allowed Flywheels to go and get reinforcements, though he had little expectation of the Duocon's return. Surprisingly, Flywheels did come back with Trypticon to give the remaining zombots a good stomping. Meltdown!


He later joined the Mayhem Attack Squad and took part in their joint attack with the Wreckers on Galvatron and Megatron. He was one of only three Mayhems to escape alive from the gruesome twosome's base, but was killed by Galvatron after the retreat to the Decepticons' heavy transport. Time Wars

Flywheels, alongside Battletrap, worked under Scorponok, who first sent them into battle when the Autobots and Decepticons were fighting over a disk containing data on the Master Sword. The Duocons' double amount of vehicle modes was enough to overwhelm the Autobot Targetmasters, and the Decepticons quickly grabbed the disk and retreated. The Master Sword Is in Danger!! Flywheels soon appeared again to defend Scorponok as he used the disk's data to manufacture the Zarak Shield. The Zarak Shield Turns the Tide
The Duocons' next mission was to hide a time bomb on the asteroid Juno, so that Scorponok could blow up Sixshot and Chromedome when the two arrived for their duel. Duel on the Asteroid Flywheels later participated in the climactic battle against the Autobots at the North Pole and retreated into space when Scorponok put his plan to destroy the Earth into motion.

Battletrap and Flywheels were created by Shockwave as early prototypes for his Triple Changer fascination. Instead of achieving three alternating modes, however, they gained the ability to separate into two different alternate modes at once. More Than Meets The Eye #8

A "twitchy neoprimalist with big feet" who suffers from a possibly made-up form of psychosomatic hyperflexia that causes him to change form when he lies, Flywheels was part of Krok's ragtag Decepticon crew along with Misfire, Spinister and Crankcase after the Great War ended. Searching for energon and supplies on the planet Clemency, Flywheels mistook the still-living body of Fulcrum firstly for a miracle and then for a zombie and an affront to Primus. Once that misunderstanding had been sorted out the group then chanced upon a P-6 Worldsweeper, a type of ship that Flywheels noted was famous only for "crashing". What they found on board the ship, such as aborted protoforms, disconnected brain modules and a robot apparently made out of wood was disturbing enough, but then they were contacted by the Decepticon Justice Division through Flywheels's communicube and given an ultimatum to surrender one of their number so that the other six could watch him die. As there were only six of them the group reasoned that the D.J.D. must have miscounted, until Krok discovered that the ship also contained Grimlock in a stasis pod. Rules of Disengagement

After agreeing on the seemingly-suicidal plan to fight their way out, the Scavengers spiked Grimlock's stasis pod with circuit speeders and left him out for the D.J.D. to find. While Tarn battled the Dinobot leader, the rest of the Decepticons tried to slip away but were ambushed in turn by the rest of the D.J.D. and Flywheels was killed by Tesarus. His surviving comrades looted his corpse for spare parts and energon and left the body on Clemency, where, 18 months later, his remains were examined by the Necrobot. Who's Afraid of the DJD?

- Flywheels (Duocon, 1987)
- Japanese ID number: D-97
- Accessories: Gun
- Flywheels's robot mode is made from the combination of a maroon F-4 Phantom II fighter jet and a brown self-propelled howitzer of vague origin that make up his alternate mode. His only articulation is the up and down movement of his arms at the shoulder, and his only accessory is a maroon rifle. The rifle can also be mounted on the tank or jet, although the latter looks ridiculous.
Notes
- The lack of wheels on Flywheels' alternate mode(s) has led to speculation that he and Battletrap may have swapped names during production. Their names are even swapped in The Headmasters episode "The Master Sword Is in Danger!!".
