@Dream: He could use Haki covered punches I guess, Human torch is still completely susceptible to physical damage, just no one is dumb enough to touch him. Unless of course enel can't use hardening haki in which case idk I kinda half ass payed attention to the skypiea arc.
Johnny's never scorched a planet before that I recall.
His Nova attacks emit heat on par with stellar temperatures (i.e.: the sun), which is considerably hotter than the heat emitted from lightning and could ignite the atmosphere and destroy everything on a planet's surface if Johnny doesn't contain his attacks to a specific point.
Also Enel being a logia and having haki, I don't think he would be harmed and if he could be harmed by Torch he's fast enough to escape.
I don't think Logia intangibility can save Enel from immense temperatures considering lightning needs warm air to mix with cold air masses to be triggered and Johnny could heat up the area he is in to be hot enough where it could screw up Enel's ability to maintain or generate his lightning form, much less be capable of generating any attacks. Haki might help Enel avoid Johnny's less immense attacks, but I highly doubt he'll be capable of evading highly destructive attacks if Johnny gets serious.
Torch on the other hand is vulnerable. He might have resistance to heat but it is fundamentally different from fire. For instance even if he could tolerate the burning aspects,'the other effects such as uncontrolled muscle flexing and shock to the nervous system could kill or knock him out.
Don't picture lightning even touching him. Johnny's body is capable of absorbing whatever heat or plasma is in his vicinity, be it from the environment, a fire or an attack. He'd likely absorb the lightning attacks since lightning is a form of plasma.
You didn't address the second portion of the last statement Johnny should still be susceptible to the effect it has on him, he could absorb the heat, but not the electrical current itself. it should still be capable of effecting him as any human would be by electricity.
@solesamurai: Still find that doubtful. Electric currents are still a form of plasma as the gas that it consists of gets ionized enough to become electrically conductive, meaning Johnny could absorb the charge before it even effects his body.
@taichokage: Devil Fruits alter the characteristics of its user's body where they take on the properties of whatever substance or element they personify or gain some sort of superhuman powers. This would include any weaknesses associated with whatever element said Devil Fruit user is associated with, such as insulators sapping Enel of his ability to generate his electric form or being wet robbing Sir Crocodile of his ability to go into sand form.
@Dream: you say this as if jhonny could get instantaneously to those tempratures, which is wrong, he tried to hold back the hulk but he didnt even got the time to flame on properly (and the hulk is slow compared to enel). enel on the other hand can release 100 million volts instantaneously which would effectively destroy jhonny's nervous system.
@othus12: Johnny's ability to absorb heat and plasma is a passive effect. Regardless of how much voltage Enel puts in his attacks, he's not gonna effect Johnny with his lightning attacks due to lightning being plasma and such attacks would only further strengthen Johnny. Johnny might not be able to immediately use his Nova attacks compared to Enel's high voltage. But it's not like Enel's gonna be capable of harming Johnny in anyway with his attacks. Speed's also not gonna be an issue for Johnny while he's in flight as he is capable of reaching hypersonic speeds.
And I wouldn't consider Hulk slow considering he's fast enough to intercept fired mortar shells and could tag jet fighters in flight with his leaping abilities.
@Dream: the electrical current travels even before heat is produced (physics 101). by the time his body absorbs the heat he will have his nervous system destroyed, he cant get around it. or do you have a scan where the human torch is immune to lightning?
also lightning speed>>>>tagging a jet. if hulk can tag jhonny enel can speed blitz.
@Dream: it actually isnt, electrical current is nothing more than electrons in movement, to become plasma it would have to be accompained by ions.
anyways. even spidey beated the crap out of jhonny so it doesnt matter, enel was pummeling luffy with a staff so you know his strenght is the real deal he could end the fight with his cloan paddling by piercing his neck off.
This is a made up story, of seven races, picked to dungeoneer for treasure, fight together and have their adventures recorded, to find out what happens, when initiative rolls stop, and natural 20's are real.
