The members of the Cobra-La's Royal Guard are genetically augmented super-soldiers with one purpose and that is protect and serve Golobulus. And they will do so to the death if they have to but that's not a problem. They are specifically bred for their very purpose and even one Royal Guard presents a formidable opponent. They wear a near impervious armor derived from their civilization's giant insect guardians. Each Guard is superbly strong and can hold its own against even a seasoned martial artist. However, as they are completely subservient they rely on brute strength and the instructions of their beloved leader to direct them in battle.

G.I. Joe vs. Transformers
In 1978 the Royal Guard and Pythona captured Joe Colton and Chok-Pa. In the present day they often worked with the Decepticon Bludgeon, who now served Golobulus. The guards were tough but not invulnerable. A squad of three was defeated single-handed by Colton and a larger squad was easily subdued by a rampaging Optimus Prime. Several guards survived and were incarcerated to await trial.
Impel trading cards
The Royal Guard received a special 'In Memoriam' card in the 1991 Impel trading card set (which was based on the Marvel Comics), even though they never appeared in any issues of the comic. The card recounts how Cobra-La's Himalayan base is buried under an avalanche without being specific as to what events transpired for it to happen.
