Marvel: Plasma Emanation

Leyu Yoshida (Sunpyre)
Sunpyre can generate plasma temperatures which match those that can be generated by the Human Torch, reaching about 1,000,000 degrees Fahrenheit at maximum level. She can also use her power in a massive blast, similar to the Human Torch's nova burst. However, Sunpyre has much more control over the area of effect, enough to where one person may feel like they have been sunbathing all day to total incineration of another target.
