Here is Crash and Burn. Two London based metahuman criminals whos names really do give away there abilities. Crash uses his vast strength and invulnerability to cause a lot of damage, while Burn can agitate atoms to create fire and immense heat.
And here we have Hotstreak, main nemesis to Zoe Thunder. Hotstreak is able to create heat that can reach 2,500 degrees fahrenheit, but she must be moving to do so. So she is usually running or flying to do this. Her top speed is unknown but she has been clocked at going mach 2 at one point.
