[Fantastic 4] What does the Human Torch smell like?

What does he smell like when he's flamed on? Is it possible for fire to burn without emitting a smell? Does he smell like a burning person? Is that distracting to any of the other members of the F4?

Well, technically he isn't on fire. What Johnny Storm does is pyrokinesis of self-generated plasma, which is more similar to lightning than actual flame. As a result, it would probably not smell of anything in particular, though the air around him may smell like ozone if the plasma destabilized the O2 in the air around Johnny into free Oxygen molecules.
