I think that if they made colossus so much stronger in the ultimate universe than ultimate juggernaut will have to be that much stronger as well in order to still pose threats to the entire X-men roster. I hate, hate, hate, hate that they had him start as a mutant but it i guess it is good because it means the gem will probably build off of what is already there giving him a much greater rise in strength. I hope...
Powers and Abilities
Until recent times, the Juggernaut possessed a variety of superhuman physical abilities mystical in origin.
The Juggernaut possessed vast superhuman strength, the limits of which were never revealed. The Juggernaut's strength was sufficient for him to battle powerhouses such as Thor and the Incredible Hulk, placing his strength well into the Class 100 level, being able to lift in excess of 100 tons. Truly, only the Hulk was ever observed to be able to match the Juggernaut's nearly limitless physical strength
Aside from his incredible strength, the Juggernaut's body possessed an extraordinary degree of invulnerability to injury, allowing him to trade blows with some of the strongest heroes of the Marvel Universe. The Juggernaut could withstand high powered energy blasts, falls from great heights, exposure to temperatures greater than that of the surface of the Sun, exposure to vaccum environments, etc. without sustaining even the slightest injury The Juggernaut could increase his invulnerability to even higher levels by generating a mystical forcefield around his body. This field was sufficient to enable him to withstand powerful energy blasts from beings as powerful as the Silver Surfer, multiple blows from Thor's hammer, and Wolverine's adamantium claws.
The Juggernaut was, literally, an unstoppable force. Once in motion, whether it be running or walking, no physical force could prevent his forward momentum. His pace could be slowed considerably by powerful energy blasts, many tons of rocks, etc. but nothing completely halted his forward momentum. This is true with the one exception of his battle with the Incredible Hulk as War II where much to Juggernaut's shock he was stopped.
The mystical energies that flowed through his body were more than sufficient to sustain him. The Juggernaut no longer needed to eat, drink, or even breathe and could survive indefinitely in a vacuum. These same mystical energies also provided him with limitless physical stamina. The Juggernaut's mystically enhanced musculature generated no lactic acids.
As a vessel of mystic energy the Juggernaut also possessed many abstract powers that had yet to be fully revealed. Before getting depowered the Juggernaut had exhibitted such fantastic abilities as mystic radar to locate his enemies seemingly anywhere on the planet, and continuing to advance and fight after having his body magically disintegrated into nothing but a skeleton.
Despite his physical attributes, the Juggernaut's mind was as vulnerable to psionic attacks as the minds of ordinary humans. However, the Juggernaut's helmet was constructed of a rare, unnamed metal found only within the dimensional realm of Cyttorak. This alloy was sufficient to shield the Juggernaut's mind from all forms of psychic and telepathic assault.
Since his depowerment at the hands of Cyttorak, however, his power levels have decreased in almost every respect. He now has to breathe, eat, drink, and sleep. While he still possesses a vast level of superhuman strength, the Juggernaut isn't nearly as powerful as he once was, nor is he as invulnerable as before. It's now possible for him to feel pain and suffer injury.
Finally, he is no longer an "unstoppable force," and has been stripped of his mystical armour and telepathy-shielding helmet (instead, he wears "unstable molecule" replicas which do not replicate the telepathic shield).
