Moonfish

Moonfish (ムーンフィッシュ) is a villain affiliated with the League of Villains and also part of its Vanguard Action Squad. He and the rest of his team serve as the main antagonists of the School Trip Arc.

Appearance
Moonfish is a fairly tall man, towering over most of his team members. His entire body is covered in a black straitjacket-like garment, with his arms bound across his chest in a X-shape, and almost all of his face covered up, save his mouth, which is held open by metal clamps. These clamps are attached to the end of three straps, which encircle his head in different locations: one attached to the lower left and right hand corners of his mouth, one attached to the upper left and right hand corners of his mouth, and the last attached to the center of the top of his mouth. There is a fourth strap that encircles his forehead; all of these straps except the bottommost one are connected in the center of the back of his head. There is another strap encircling his neck, which is connected in front to yet another strap that runs down to about the center of his body, just below where his arms are crossed. Attached to this center strap is the one that keeps Moonfish's arms bound, which encircles his torso and is attached at the back to a similar restriction device, which climbs his back before splitting in two, eventually reappearing in front across both of his shoulders, where they then disappear into the folds of his garment. This Y-shaped strap also continues down Moonfish's back to just below where his elbows hang, where it is attached to still another strap, which is wrapped around his waist. A similar positioned strap is just below this one, and is also wrapped around the waist, and is also notably the last of the leather straps around his main person. All of these straps are black in color, with red spikes in evenly spaced intervals spanning them, both front and back. A wrapping of similar straps is also around either of his legs, starting a few inches below the knees and ending at around his ankles. Between the first set of straps and these ones, there is nothing but the usual straitjacket suit, with light-colored soles at the bottom of his feet.

Personality
Moonfish is a very disturbing individual, who gains a perverse sense of pleasure from seeing dismembered body parts. During battles he's longing for flesh, begging his enemies to provide him with more.

History
Nothing is known about Moonfish's past save that he is an escaped death row inmate.

School Trip Arc
Moonfish, Spinner, and Kenji Hikiishi meet up with the other members of their team on the cliff side overlooking the Yuuei training camp, with the bound man mumbling about their job. After splitting up from the others, Moonfish encounters Mezou Shouji and Fumikage Tokoyami and attacks them. As a result of this sneak attack, the bound man cuts one of Mezou's arms off, although the two manage to escape him ultimately. Left alone with the severed appendage, Moonfish admires it, while also murmuring to himself about getting back to the job at hand. He is approached from behind by Katsuki Bakugou and Shouto Todoroki, and stands up, dropping Mezou's limb to the forest floor. He turns to the two heroes-to-be, affirming his need to get back to work. He then activates his Quirk.

Moonfish attacks Katsuki and Shouto, forcing them on the defensive. Suspended off the ground via his Quirk, the villain bemoans having to endure this situation, telling himself once again to do the job. He then attacks Katsuki once more, splitting his tooth blade in an attempt to catch the youth off-guard. Almost immediately he is attacked by Shouto, but manages to avoid the Yuuei student's ice by quickly anchoring himself to the top of one of the surrounding trees with his Quirk. He then hangs upside down in the air, asking his adversaries to show him flesh.

Moonfish attacks Shouto next, managing to inflict a wound on the youth's right leg. Now suspended between two trees, the bound villain continues his onslaught, leaving his opponents no room to counterattack. Moonfish then hears the sounds of Izuku Midoriya and Mezou Shouji crashing through the forest, with an out of control Fumikage Tokoyami chasing after them. Distracted from his initial targets, Moonfish sends one of his tooth blades at the new arrivals, only for Fumikage's Dark Shadow to flatten him into the ground, shattering his teeth.

However, Moonfish quickly gets back up using his teeth and is enraged at Fumikage, saying that he cannot forgive him for trying to steal his prizes. He attacks the shadow-using student, stabbing through the shadow arm that has grabbed him and its head. This has no effect on the creature, however, and it extends its arm through the forest, smashing the villain through multiple trees before throwing him forcefully into another group of them, incapacitating the bound villain.

Later, after the rest of the Vanguard Action Squad succeeded in fulfilling their mission, they left the defeated members of their group behind. Still unconscious, Moonfish is arrested by the Police Force.

Quirk and Abilities
Unnamed Quirk: Moonfish's Quirk gives him the ability to enlarge, grow and manipulate his teeth. Moonfish's teeth are quite strong as they were able to break through Shouto Todoroki's ice. Moonfish also uses his Quirk to maneuver around.
