Some twins are cute!

Transformertwins often share a closer connection than other forms of Transformerrelatives. The exact process by which an 'unborn' Transformer becomes a twin varies by universe; most modern stories opt to use the idea of a single component used inreproduction (protoforms,sparks) splitting. Twin characters tend to actyounger than other characters, although this is not a hard-and-fast rule.

Some twins are surprisingly badass!

Jetstorm andJetfire are the result of a split protoform. Originally refinery workers, they were injured in an industrial accident, making them ideal guinea pigs forUltra Magnus's anti-Decepticon initiative. They apparently possessed identical circuitry, which made it easy forRed Alert andPerceptor to operate on them. After they were upgraded withDecepticon flight protocols, they gained additional firepower and the ability to combine intoSafeguard.First (and Second) in Flight

... And some twins are hated by everybody.

Two Transformers that were twins had a special relationship to each other. The two were intimately linked. Their relationship was so close, they considered the other to be their other half. Twins could choose to assume individual alternate modes, or form one half of a larger, more durable altmode.

When one twin died, the other felt a temporary surge of pain, but continued on afterwards by himself.

Skyquake andDreadwing were, according toDreadwing, twins formed from a "split Spark", a phenomenon in which the spark meant to create one Cybertronian splits and creates two Cybertronians. This results in the twins having a much closer relationship than non-twin Cybertronians could ever have. Dreadwing stated that he actually felt whenSkyquake died, and thus his vendetta against the Autobots is much more personal than any other Decepticon.
