"Primus in the hand basket...I'm gooed!"

Cohesive Control Liquid is a weird substance invented by Doctor Dalton. It has properties that include the ability to control other robots, provided they are sentient.

Its effects can be countered with "defense spray".

The Great Transformer War

When the Decepticons invaded the planet Eran, they captured Doctor Dalton and forced him to outfit the Terrorcons with numerous upgrades, including the sticky goo. Following Abominus's defeat by the Technobots, the Terrorcons separated and sprayed Computron with the weapon. Computron was compelled to obey their orders, and marched over to stand with the Decepticons. Though all seemed lost, Dalton revealed his trump card; since the liquid could only affect robots, they could use his new Exosuit to fight back. Spike Witwicky donned the Exosuit and, as Computron attacked him, used the "defense spray" to disable the liquid's effects. Computron thanked Spike before taking his revenge on the Terrorcons.
