Nekro (Boss)

Nekro is the boss of The Penthouse and the final boss of Mother Russia Bleeds as a whole.

Appearance
Nekro is an entity resembling a human skeleton with sockets that have been malformed as if it had a furious look in it's eyes, a red Mohawk that fades into back at the top, and at least three golden teeth.

It wears a studded leather jacket with red cuffs, a pair of track pants, both of which have white stripes going down the sides of the respective articles of clothing, and a pair of black shoes.

In it's final phase, it sheds it's clothing and gains a layer of musculature around it's body, although it still retains most of it's sketal features.

Personality
Nekro does not technically have a true personality, considering it is a hallucinatory manifestation of both the four protagonists collectively shared addiction to it's namesake drug as well as their Ids, and thus is not technically a real being, even in the game universe of Mother Russia Bleeds, although in it's hallucinationatory appearances, it demonstrates enough character to warrant having a section anyways.

Nekro rarely speaks at all, and when it does speak, it speaks in an odd manner best described as primitive, as there are no points in the game in which Nekro speaks in a complete sentence with proper grammar, as it threatens the protagonists when it begins it's third and penultimate phase with the phrase "Die...You...Die", among other examples.

It is normally emotionless, but it noticably becomes enraged when the protagonists try to break their Nekro addiction habit, and starts insulting them the first time they mentioned it, muttering "Useless...Worthless...Shit...", and "You... Miserable... Weak... Scared...", and it becomes increasingly angrier with the protagonists at the fight goes on and our heroes get closer and closer to besting it and symbolically defeating their addiction.

Description
Nekro is the manifestation of the protagonists' addiction to Nekro and appears throughout Story Mode in increasingly more sophisticated forms, reflecting their growing addiction to the drug the being derives it's name from.

Nekro makes its first appearance in The Jail as a small hedgehog/lizard-like creature and reappears in the proceeding levels (with the exception of The Club) in increasingly "evolved" forms, going from its hedgehog form from The Jail, to a chimp-like form in The Squat, then as a hunch-backed humanoid wearing a pair of sweatpants at The Train before adopting its final form: a completely upright and fully-clothed skeletal humanoid in The City.

Nekro's final appearance is in The Penthouse, where he appears in a hallucination occuring after the scuffle with The Premier. It attempts to goad the protagonists into taking more and more of the drug which it derives it's namesake from and gets furious enough to begin attacking them after they reject it's temptations, engaging them in a final battle of epic proportions, with it trying to kill them indirectly in two different ways; a wall of meat with snapping maws defeated by syringes and a rain of fists from above, and after these attacks are bested, Nekro becomes furious enough to physically attack them, using various different methods, and when this proves insufficient, it grows a layer of muscle around it's body and proceeds to engage in bilocation, but despite all of it's efforts, Nekro finds itself defeated by the protagonists, although it may have the last laugh depending on whether or not they took the namesake drug during the battle against it.

Enemy Behaviour
Nekro is easily the most complex enemy in the game, as it possesses a wide variety of attacks and four different phases which will be broken down as following.

Phase 1 - Walls of Flesh
In this phase and the next one, Nekro won't actually attack you directly. Instead, it will summon a wall of snapping mouths and needles that slowly close in from both sides while Shadows appear to attack you.

In order to get past this phase, you must toss the needles that the Shadows carry into the Walls of Flesh.

Phase 2 - Descending Fists
In the second phase, Nekro will begin to summon giant skinless fists from the ceiling of the Nekro Dimension that slam into the floor, pinning any player character underneath them if they connect, while Needle Beasts will also appear to attack.

This phase is very simple to pass, as all you have to do is attack the fists while avoiding the Needle Beasts.

Phase 3 - Direct Confrontation
In the third phase, Nekro will finally begin to physically attack you, using a variety of attacks, ranging from disappearing and reappearing while preforming charging punches similar to the Thugs, violently descending from above and stomping with such force that it shakes the earth and causes player characters to fall down, transforming one of its arms into a tendril of meat, and appearing at the upper center of the room and summoning a wave of needles, which tires it out and leaves it vulnerable.

Phase 4 - Bilocation
In the fourth and final phase, Nekro will become surrounded by a layer of muscle and duplicate itself. This phase is identical to the previous one, but with the hazard of an additional Nekro to deal with.

Trivia

 * Nekro's tendril attack is a reference to Akira, and the animation of the attack is likely to be a reference to one of the super moves of K9999, from the King of Fighters.
 * Nekro itself may or may not be a collective hallucination among Nekro Users, given how its likeness appears in grafitti, and in the case of Masha the Bear, a mask, throughout the game.
 * If you achieve the good ending, Nekro's corpse will remain after the hallucinatory battle with it ends. This is likely to be a bug instead of anything intentional.
 * It is implied that the entire hallucinatory final battle against Nekro is simply a brawl between the protagonists and various different enemies, given how corpses of enemies that were not there before will show up after the battle against Nekro ends. Also, some of it's attacks slightly reflect the attacks of certain enemies, such as his Descending Fists behaving like the Dogs pounce attack in that the player must press many buttons to free themselves,
