There is a lot of X-Men characters. by far who is the most dangerous one to you guys. without no power ups or nothing, just using their regular mutant powers.

Rachel Grey....at the moment she's the strongest telepath in the world, a molecular telekinetic, enjoys reading minds and has devdloped PTSD at least 3 times from witnessing/being part of massacres.... Also has time travel abilities. If the chick snapped the world would fall apart.

Tempus I would say atm

Rachel would have to go 100% off the deep end or be controlled before she would do serious damage to the timeline. Tempus on the other hand is much younger, has no where near the experience, and really hasn't been taught the whole "great power, great responsibility" aspect of having her level of power

After what tempus did, she now wears the crown. Magik and rachel are dangerous and have bad temper but they are grounded. Rachel listens to her team mates. Magik can go darkchilde anytime but at the end of the day she still gets in touch with good heart.

teen jean grey cause she scared of becoming phoenix

anxm 41 coming in april, watch for it!!!!!!!!!!!

They all are very dangerous in the right situation. Wolverine, one of the least powerful for example, is considered one of the most formidable X-Men.

This.

each of the X-Men given the circumstances can be incredibly dangerous. It terms of basic POWER sets... there are SO many X-Men who could be accidentally lethal. ALL telepaths and telekinetics. All the elementals (Storm, Iceman, Firestar, etc), Tempus, Magik, Nightcrawler... seriously they could all kill without thinking. Adding in SKILL sets and Psylocke, Wolverine, Storm, Rachel, Magik, Gambit, Nightcrawler, Colossus... they're all deadly. And many many other x-people can be lethal.

I think almost all super-heroes have lethal potential. its why they are super-heroes and not villains, they choose to limit themselves to non-lethal uses of their powers and abilities or reactionary lethality, rather than outright murder.

X-23, Psylocke, Magneto, Magik

This is the reason i say Tempus is the most dangerous currently...all of those character listed have all been in the game for quite a while and are somewhat grounded in that they have the experience to know when NOT to use their powers, or at the very least their powers are basic enough that they would only cause damage to those in their immediate vicinity (wolverine for example).

Tempus on the otherhand has it in her powerset to completely destroy entire timelines, erase people from existence, and in general radically alter the fabric of history. And unlike all those other "dangerous" mutants, she has not had years of working as a team under the Xavier dream, she has not been taught that there are times NOT to use her powers. She is young, impulsive, as seen in the Malloy arc is perfectly willing to risk time/space to change something she deems needs to be changed. This is what makes her the most dangerous. She has the power, and her standard mindset does not prevent her from abusing it. Storm or ice man could render the entire planet uninhabitable with an ice age if they wanted...but they wouldn't unless completely out of their mind or heavily manipulated (ie: possession, mind control, ect) Tempus could change all of history because she felt no one was listening to her when she felt she was right.

Storm, Rachel, and all the other upper level mutants may have the power, but they have grown to the point that they know there is a time and place to use it. Eva has not, as of now rewriting history is the only way she really has shown to solve problems.

@lordmordor: totally in agreement. Tempus does lack restraint and understanding of the repercussions of her actions.

They are ALL dangerous give the right set of circumstances (ie. mind control, possession etc) but without all of that, it's got to be Tempus...

She is one of the most powerful of all the mutants that emerged after AVX, hence she has limited use of her powers, also lacking the years of mental control and morals of when to use their powers, like the rest of the X-Men.

She has willingly erased people from history and manipulated the fabric of time...

Tempus, then Illyana(she can do the same stuff, right? She's been travelling through time for a hella lot longer) then telepaths generally

@hopesummersforthefuture: i think teen jean refuses to be phoenix but i think refusing to be phoenix makes her more prone to becoming xorn.
