I'm counting his fight with Doriate, where he molded devil slaying ice the first time. I should have listed it as five and then put in that fight as an addendum, so I guess that's my fault. But thus far, in the six fights involving ice (better phrasing) Gray has re-shaped ice in three of them. But my point still stands. Gray can beat another ice user of higher strength just as long as he can get a hand on their ice, provided they aren't Ice-Make users, which as we've seen mostly come down to strength (or playing the mommy card, as with Ultear's fight).
