You could not have chosen an easier OP character for me to support, you just chose one of my favorites and one of the most powerful.
Enel can bust out casual attacks that are more powerful than Kirins, said casual attacks would vaporise Itachi. Susano'o could arguably block El Thors, but Susano'o drains Itachi, and with Enel's powerset it is well within Enel's power to play keep-away until it drops.
Kisame is a water type, Enel uses El Thor, it's super effective!
Tobi's attack requires getting right next to Enel and becoming tangible. Which is actually a sort of bad idea, considering Enel happens to have a body made of ****ing lightning, that he can use with a thought. He could electrocute Tobi, or knock him back with a thunderclap by heating the air around him.
Hiruzen? What, seriously? Hiruzen showed absolutely nothing that doesn't point towards "One-shot by an El Thor".
... I find the statement at the end of your post ironic. If that is true, why use Enel as your example, aka, one of the most powerful ranged fighters in the series?
Also on the subject of Enel vs Tobi, Enel is perfectly designed to counter Tobi trying to warp him due to Enel having Mantra, which gives him precognition. Precognition + faster speed + superior reflexes + powerful attacks = Dead Tobi.
Well if Rikkudo's feats are specified further, he would bethe strongest character in the HST escentially because he could do whatever the **** he wanted to do.
Roger was killed by mortal men though, and was also dying of illness
Some people forget that Haki users have precog, so adding that to absolutely superior reflexes makes it so the advantages some abilities might give Naruto characters in certain matches are rendered moot.
Goku had gods that resurrected people and future tech, Gol was a hunted man who lived in a primitive era from our standards, a very basic sickness could be lethal at Gol's era.
Dude just think about it
Itachi and Enel meet at the battle place,Itachi points a finger at enel,enel looks at the finger *Game Over*
Or set the entire environment on fire with amaterasu enel will eventually get caught in it
Kisame turned an entire forest into a dome of water when he only had 30% of his chakra imagine how much much water he can make at 100%
Tobi has thaousands of tricks up his sleeve and he can use izanagi if something doesn't go his way
for the last i didn't choose enel the aura angel did
Hidan is immortal, he can only be beaten if his limbs are severed so he can run around and distract enel then kakuzu can use his water release heart to drown him. and also kakuzu has a lightning release heart (which is naturally immune to it's own element) which can act as a sheild
Against someone with precog and incredibly high physical abilities I see none of that working, even ignoring the speed advantage that Enel has in both human and lighting form.
