Half Hot, Half Cold

Half-Cold Half-Hot ( Hanrei Han'nen?) is the Quirk used by Mai Todoroki.
Description
Half-Cold Half-Hot allows the user to generate ice, frost, and cold from the right side of their body and fire, flames, and heat from the left. However, the user is unable to manipulate either element that comes from an external source; they can only create them from their body.
Half-Cold Half-Hot's power is perfectly divided between the right and left sides of the user's body. This gives the user two powerful, separate methods of combat that they may use regardless of the other.
Weaknesses
The user needs to constantly alternate the use of both elements, heating themselves with the left side after creating a great volume of ice or cooling with the right side after generating strong flames. Overuse of either side without the other to regulate their body temperature could lead to either frostbite or overheating affecting their whole body, with possibly fatal consequences.
