Enel had two teachers: Golden Lion and Garen.
Golden Lion was responsible for training his physique, tempering his will, and teaching Enel all kinds of practical close-quarters combat techniques.
Golden Lion was an old-school, hard-core powerhouse who had always regarded bloody, fist-to-fist combat as a basic quality of the strong.
So despite possessing the Float-Float Fruit, which allowed him to fly freely through the skies, he had still taken the initiative to land when he went to Marine Headquarters for revenge, engaging Garp and Sengoku in close combat.
Garen was different.
He believed only in victory and did not care about a man's romance or the ceremony of a duel.
If Garen had taken Golden Lion's role back then, he would definitely have prepared dozens of floating islands and dropped one on Marine Headquarters every day.
Then he would run after dropping it, leaving no one able to catch him.
If he repeated that for dozens of days, the Marines and the World Government would be unable to stay open for business.
So while Golden Lion taught Enel to charge into close combat crackling with electricity and unleash a whole set of lightning fists and thunder kicks, Garen taught Enel a tactic Golden Lion called shameless and utterly without limits:
Kiting.
Enel possessed a special Observation Haki with a range spanning tens of kilometers, allowing him to sense enemies from extremely far away.
And his Rumble-Rumble Fruit could influence the weather, manipulate the thunderclouds in the sky, and bring down divine punishment from beyond visual range.
Beyond-visual-range radar targeting, beyond-visual-range attack methods.
In Garen's eyes, this was clearly an ultra-long-range artillery platform with an attack range comparable to Xerath's, plus an auto-aim script. Why insist on brawling at close range with those tanky fighters?
"He..."
