Decimate him? No force on earth has yet been known, now a days, to stop juggey! Slow him considerably, Yes, but hurt or STOP him, NO! He still stays juggey now with his helmet on, hes an unstoppable tank of destruction... I mean... come on...
Juggey possess unknown powers, mystical in nature, which enhances his strength to an as yet unknown degree and makes him a seemingly irresistible tottally unstoppable being. Once he begins to walk in a certain direction, no obstacle or force on Earth has been observed to be able to stop him.
Some obstacles (many tons of rock, for example) or forces (such as plasma-discharge cannons and super psionic attacks without his helmet) may slow his pace considerably, but nothing has yet stopped him permanently from advancing.
The dude has extrodinary resisant to virtually anything from the stone of cytorak, I mean Juggernaut can even shield himself even further from injury by mentally surrounding himself with a force field. Enveloped by his force field, the Juggernaut has survived the fiery explosion of a truck transporting a huge quantity of oil without any injury whatsoever.
The Juggernaut can survive indefinitely without food, water, or oxygen. He is sustained by his mystical energies alone, the magic in his blood, even, get this, even destroys all diseases, poisons, mind control, and even stops incoming nightmares and mind destruction attacks (However, venom has proven that his symbiotes nightmarish attacks do some damage, but no other nightmares have stopped him, not to the point of venoms)
I mean... Tell me... Gladiator can beat that?
