A duo of Goopanoids invaded one of N-Tek's facilities in order to steal the Tox-Bomb from their Chemi-Volt. In the process, one of them were eliminated and the other one managed to get C.Y.T.R.O.'s controls and used it to steal the Tox-Bomb. Eventually, the creature was found by Max Steel, who eliminated it.
The Goopanoids are made out of a shiny and transparent green toxin with many lime dots around their bodies. They have a slightly muscular body with large hands and feet. They possess monstrous features and stand on hunched over posture. They have lime eyes, exposed pointy teeth, five fingers and her feet are almost claw-like.
After the time skip, The Goopanoids' design remains virtually the same, with the exception of their teeth, which are now white, their eyes, which are yellow and the lack of lime dots.
This variation gained an action figure in the toy line in a pack named Toxzoid Target Blast. Interestingly, the name "Toxzoid" featured in the package is also the same as the creatures that served as Toxzon's henchmen in the classic series.
