Juggernaut is an incredibly awesome swimmer and has also been known to walk though air.  
 
Plus he doesn't need to breath lol, no watery death unless its magical reality warping water, and even then, its going to have to be more potent than what ever that puny sissy place Oblivion is. 

" Ok, I understand the whole "Once he starts moving, nothing can stop him" thing. Well this just means it takes a while for him to stop. Lets say you are being trailed by Juggernaut and he wants to kill you. Couldn't you just oh I don't know... find a cliff overlooking the sea and get him angry so he charges you, side step (don't try to trip him moron) and watch as big bad Juggernaut goes falling into a watery grave... because I kinda doubt he can swim with all that Armor on...  Give me your opinion on this: "

Juggernaut's biggest weakness, is writers who aren't creative or don't understand the original purpose or appeal of the Juggernaut, or maybe they do, and they just want to blend him into a generic character or something. 

Bwhahah, thats great how three posters posted the same thing at the exact same time.

In fairness though, how can you beat full power Juggs with a regular X-Men team?  (I say X-Men because he's primarily an X-villain). "

 In what context do you mean my friend, I am not sure which part of my post you are referring to sorry.  "

" The reason why they make him powerless. He is just too strong  for a non-conqueror a la Doom type. "

"But let's be honest, without a plot device, there's no way Juggs is going to surrender his helmet. A thunder clap is sufficient to drop Longshot, Dazzler and Betsy, and Rogue should have been put down with a punch. Full power Juggs, not including 8th Day/Trion etc... is beyond WW Hulk in strength.

 I tend to disagree depending on how we both personally view Doom. A dozen X-Men stories demonstrate that strength isn't everything. to me its more about wishing to use a mid level popular and recognizable character more often, as for the reason he is often depowered. Funnily enough this tends to coincide with some writers who have written him this way lol "

Juggernaut wasn't just strength. He was magic. "

His only weakness is lack of intelligence.

@Mikepool: From an observation his powers seems to be bound on earth's gravity (since if he's unstoppable then why not just go out of the earth's orbit in a straight line like light does?), he hasn't been tested on slippery surfaces or ramps yet ( I mean a carefully placed banana peel could do it), and once somebody takes out his magic (like the depowerment before he teamed up with wooden black tom) then he would hella weak.  He seems to also have a disability in bending corners while in top speed. An easy answer would be a power negator/nullifier and some heavy firepower (in that order) to kill him dead.
 
P.S. being a hero makes him weaker than al that combined.

I have said this before. But his biggest weakness is bad writing. Can anyone tell me what his motivations are leading up to and during the Fear itself event?   The T-Bolts gave hints that Cain wasn't happy being under Cyttoraks sway (ridiculous notion on a few fronts BTW). And during FI it is stated he could use his Cyttorak granted powers to keep himself from being taken over by Kuurth. But chose not to.  What?   And somehow Cyttorak can sense when the Enigma force uses Cain for half an issue and depoweres him. But is unaware Cain has been completely taken over by something else?
