The one in universe -137, the only negative universe recorded so far, is very shy and always cold. It is better not to take him to very cold places because he could die of chills, nor to take him to very hot places because he can die of heat, his body temperature is very strange, he was abandoned by his parents in Antarctica, therefore he becomes too attached to everyone, his brain is like a child's, that's why he never thinks about things 18+. He has ice powers but he doesn't know it.
