The beginning of Attack On Titan introduced one of the most horrific events in anime history; massive giants - otherwise known as titans - spilled through the walls of Shiganshina, devouring everyone they found behind the barrier.
This caused an unprecedented disaster and dramatically thinned the populace's numbers before they could flee to safety. However, the success of the titans' attack in one universe does not guarantee it in another. Through measuring how the characters of One Piece would fare under these conditions, we can accurately determine how deadly the assault actually was.
10 DIE: Morgan's Reliance On Physical Strength Would Be His Undoing
Axe-Hand Morgan was a former despotic marine who wielded unprecedented strength. A single sweep of his arm was able to decimate the ground and cause a large crevice to form. This entails that he might stand a chance against the titans for his raw striking power.
However, the man possesses neither durability nor speed. As a consequence, though he may be able to defeat a single titan, he would quickly find himself overwhelmed in the event that other monsters have joined in the fight against him.
9 SURVIVE: Buggy's Devil Fruit Would Save Him From The Titans' Grip
Buggy's Devil Fruit allowed him to disperse his body in slices. This made him impervious to blade attacks, as he could reassemble on a whim.
Though the clown might not have the most impressive agility or strength, his power would allow him to slip through the titans' fingers whenever they grabbed him. Even if they were able to devour parts of his body, he demonstrated an ability to survive with only a fraction of his original form (though it would make avoiding subsequent threats more challenging).
8 DIE: Wapol Is Slow & Has A Limited Arsenal
Wapol is one of the few characters of the One Piece universe to have a chance of devouring a titan instead of being eaten himself. The former tyrant is also able to transform into things he had eaten previously, including cannons and even houses.
However, the titans have proven capable of destroying both effortlessly. Considering that it takes Wapol a moment to distend his jaws before eating his targets, his foes have an advantage in both strength and expedience, devouring him before he could ever use his devil fruit against them.
7 SURVIVE: Crocodile's Physiology Would Make Him Impossible To Touch
Crocodile was able to disperse his body into grains of sand, making him impossible to physically restrain unless covered in water. Considering that the titans are neither intelligent enough to or have the resources for his demise, they stand no chance of apprehending him.
However, the Warlord's favored dehydration tactics would be ineffective against his opponents since they subsist (primarily) on sunlight. Further, his poisoned hook would have little effect on their altered physiologies. Though he would be able to make a safe retreat, he's poorly equipped to defeat the towering monstrosities.
6 DIE: Arlong's Overconfidence Would Spell His Undoing
Arlong commanded formidable physical brawn. He was capable of catching and shattering a cannonball in his jaws and destroying marble pillars with a single sweep of his hand.
However, these are both feats that titans are equally capable of accomplishing. The Fishman's pride would prevent him from retreating, compelling him toward a battle that he couldn't possibly win. As durable and sharp as his teeth might be, they are ill-equipped to contend with the sheer mass of his adversaries.
5 SURVIVE: Shura Is An Expert Aviator Who Could Fly Away
Shura was a High Priest of Eneru and brilliant aerial navigator. He was skilled enough to defeat Chopper and even single-handedly overcome the Sky Knight, the latter of which was the previous ruler of Sky Island.
His navigation skills would enable him to fly well above the threat of the rapacious and waiting titans. Moreover, Shura's preparedness would even overcome the leaping abnormals that might attempt to snatch him out of the sky. Should he be imperiled, he could blind his opponent with a pillar of fire from his lance.
4 DIE: Doublefinger's Spikes Would Be Worthless Against A Titan's Hardened Skin
Doublefinger was able to transform various parts of her body into penetrating weapons. Her devil fruit was also versatile enough to enhance her physical strength when necessary.
However, her penetrating spears were not even capable of completely impaling Nami during their fight in Alabasta. Consequently, they would stand no chance of causing meaningful harm against the hardened skin of the titans, especially since they are impervious to pain and could ignore her spines as she is being devoured.
3 SURVIVE: Smoker's Body Is Impossible To Consume
Captain Smoker was able to disseminate his body into gouts of air. This made him an elusive and treacherous opponent, one whose devil fruit was complimented through his martial expertise.
It also entails that the titans could not hold him once they wrangled the man into their clutches. While the marine may not possess profound speed or durability, his unique physiology would enable him to make a comfortable retreat without worrying of being consumed by his hulking pursuers.
2 DIE: Kuro Lacks Precision & Striking Power
Kuro was able to ascend to astonishing speeds through his "Pussyfoot" technique. Complimented by his bladed claws, the villain reached speeds faster than the eye can see, entailing the titans may not be able to catch him.
However, he cannot control himself under high velocities, making the busied streets of Shigashina extremely hazardous to him. Moreover, his blades are easily broken and could not inflict substantial damage against the titans. Considering these two factors, he is neither skilled enough to avoid his opponents or able to fight them off.
1 SURVIVE: Eneru Has A Number Of Ways To Avoid Harm
A man of tremendous ability, Eneru has a number of ways by which to avoid harm. His most immediate advantage is through his lightning physiology, one that guarantees he is impervious to physical attacks (and can automatically retaliate against such efforts against him).
Failing that, he is also capable of anticipating the titans' sluggish movements and reacting accordingly. Further, he could simply teleport behind the second wall and relish in the carnage as it continued to unfold. Though Eneru is capable of killing titans through concentrated blasts of electricity, he would find them beneath his attention.
