Valve

Valve is an Autobot Wrecker and a Decepticon Squadron X member from the IDW portion of the Generation 1 continuity family.

I'm the jackass white guy in the background!

Valve seems a bit indecisive. He is Spark brothers with Springarm and Wheelarch.

Fiction

IDW Generation 1 continuity

Valve was a founding member of the Autobot Wreckers. Macabre's Squadron X profile

The Wreckers' 11th iteration, including Valve, battled Black Shadow and suffered three casualties. Rules of Disengagement

He later defected to the Decepticons and became leader of Squadron X. He was succeeded in that position by Macabre. Macabre's Squadron X profile

Later Wreckers preferred to forget his still being alive when considering the fact that all of the founding members of the Wreckers were dead. Zero Point

Notes

• We don't yet know why Valve switched sides. What we do know is that it was after Whirl joined the Wreckers. Whirl is responsible for the death of Springarm and Wheelarch. Hmmmm.
