pyrogenesis means you can create fire, whereas pure pyrokinesis you wold first need a source. typically, pyrogenesis and pyrokinesis are rolled into a single power, such as firebending in Avatar and Korra. Cryogenesis is the same, the ability to generate cold and ice, which is typically combined with cryokinesis, the ability to control cold and ice.

Heroes was a tragically short lived show based in an alternate version of our own world, where a large number of people suddenly start exhibiting superpowers such as, well, everything. time-space manipulation, enhanced strength, enhanced hearing, regeneration, it's hard to explain how it was different from typical superhero shows, you really have to watch it to understand.
