North Ember, or Icebreaker, is the Top 2 of the Top 5. His ability is ice, which lets him create ice in any shape or form. His main weakness, of course, is heat. His body temperature is a lot lower than other people, and that's the norm for him. His body can take very low temperatures (Under 0) for a long amount of time (More than 24 hours) But, if he's exposed to too much heat for a long amount of time, he'll be weakened, or better yet, dead. In this picture, his weakness is being exposed during battle. Keeping him in a hot metal box for a long amount of time will kill him. You may be thinking "Why doesn't he just use his ice to keep cold?" Well, after a certain amount of time exposed in heat, his power gets weaker and weaker, to the point of not working anymore until he's cooled down. Staying in a metal box for about 5 minutes, sure, he'll be able to cool himself down, but not for long before his power stops and he most likely dies. But anyway, that's North's weakness explained, onto the next character!~
