i think vin also beat someone with it, so you aren't unbeatable in it. but i don't remember the circumstances, just that they were very unusual and not the most reproducable thing in the world. doom isn't the fastest guy in the world (he can reach high speeds sure, but his combat speed isn't the same to match it).
but yeah, that's what i think that metal was. was thinking atrium or something to that spelling so that'd work. precog to the point where you would know everything seconds before it happens, a major speed boost too i think? main thing i remember that turned them into army killers at least.
overpowering doom though, straight up? i.... don't think that's the easiest thign considering her universe's generally low power and while doom isn't crazy high he's got a lot of tricks, his force fields are solid, and can blast people to high hell. you don't exactly take on the fantastic four and be a jobber - between the Thing and Sue you've got a lot of power needed, and ways to get around both direct and indirect combat.
but he's a dude in metal. figure, counts for something. don't know the rest of her tools, so yeah. data necessary.
