Semblances do appear to correlate with personalities a lot, but Weiss' Semblance is hereditary. Every single person with Schnee blood has the exact same Semblance, according to Winter. But not everyone with Schnee blood has the same personality. So that kind of kicks the "Semblances come from their personality" theory a little bit.

Again, the whole "A person's Semblance can become something else entirely if their personality changes or they go through something traumatic" thing is 100% fan theory, and I think we should refrain from assuming that's true. Miles and Kerry said that Volume 5 will explain a little more about Semblances, so maybe once Volume 5 is over, we'll have more information to help us figure these things out.
