Author's Note: The last time I created a fanfic was year 2013-2014(?) and it was everything Hetalia (You may check my profile and feel free to read) and stuff but now I do not have a reason to continue my works considering the spark was gone and I lost my interest with the anime. Moving forward, I finished school and have decent work, life has been complicated than before and now I got interested of watching My Hero Academia, I decided to write this Alternative Universe Villain! Deku. This is also inspired by League of Legends Champion, Jhin. The Virtuoso.

Enjoy reading!

Introduction - The Lore

"My genius will be understood – eventually."

Midoriya Izuku is a meticulous criminal psychopath who believes murder is art. Once a prisoner in an infamous villain detention facility, but freed by shadowy entities within Heroes ruling council, the green-haired serial killer now works as a lone wolf, the cabal assassin. Using his gun named 'Whisper' as his paintbrush and his adamant knowledge of hero/villain analytics, Izuku creates works of artistic brutality, horrifying civilians, heroes, and even villains. He gains a cruel pleasure from putting on his gruesome theater, making him the best choice to send the most powerful of messages: fear and terror.

For months, multiple provinces of Japan were greatly plagued by the infamous "The Deathsinger". Throughout the province of Japan, a monster slaughtered scores of travelers and sometimes farmsteads, leaving behind twisted displays of lifeless corpses scattering on streets. Police force, military and pro-heroes from different hero agencies searched the forests, and patrolled the roads – but nothing slowed the beast's grisly work.

A great desperation to speed-up the investigation, the Hero Council sent and envoy to beg the hero, All Might of U.A for help. Upon hearing of the nation's plight, All Might feigned an excuse for why he couldn't help, as his strength has been weaker than before. But a week later, All Might along his star students and hero in-training, Young Bakugou and Young Todoroki disguised themselves as merchants and moved to provinces. In secret, they visited the countless families emotionally shattered by the killings, dissected the horrific crime scenes, and looked for possible connections or patterns to the murders.

Their investigation took weeks, and left the three men changed. All Might, as usual have weakened due to long and tiring case; Bakugou, known for his arrogant and unruly attitude became somber; and Todoroki, one of the Class – A's brightest star of U.A began to struggle with his studies and trainings. Upon finally finding a pattern to the killings, the All Might is quoted as saying: "Good and evil are not truths. They are born from men and each sees the shades differently."

Depicted in a variety of plays and epic poems, the capture of "The Deathsinger" would be the seventh and the final great feat in the heroic career of All Might. On the eve of the Cherry Blossom Festival in Tokyo, All Might disguised himself as a renowned calligrapher to blend in with the other guests. Then he waited. Everyone had assumed only an evil spirit could commit these horrifying crimes, but All Might had realized the killer was an ordinary teen. He was wearing black leather boots, dark green silk textured cloak and hauntingly crafted wooden mask hiding his real identity.

Bakugou and Todoroki were given a break after tiring investigation and they were replaced by Kamui Woods and Ingenium. When they caught the killer, Ingenium marched forward to kill him, but All Might held him back. Despite the horrors of teenager's actions, the legendary All Might decide the killer should be taken alive and left at high security detention and prison center for infamous villains and criminals alike. The two disagreed, but accepted the heroic logic of All Might's judgement. Meanwhile at U.A's class – A room, Bakugou and Todoroki disturbed and haunted by the murder scenes they had witnessed and endured, but thankfully their classmates and teachers such as Aizawa and Midnight helped them recover and regain their sanity and accept the real cycle of life and death. A day after the killer's imprisonment, the Hero council and government did not disclose the killer's identity for safety of all citizens despite the backlash of mass media of both national and international press.

Though, imprisoned for a few months, the polite and shy Midoriya Izuku revealed little of himself – even his history remains unknown. But while as a prisoner, the police and hero wardens noted he was a bright young man who excelled in many subjects, including analytics of future heroes and villains, sketching detailed costumes on his sketch pad, physical and combat session in prison. Regardless, they could find nothing to cure him of his morbid mannerisms such as talking and mumbling to himself while facing at the wall; staring and smiling at his co-inmates and wardens sometimes scared the shit outta them.

Outside the prison, Tokyo fell into turmoil as the League of Villains wrath led to instability as they unleashed destruction first at U.A, where students and heroes frightened, some were fighting back towards the villains. The uprising awoke the tranquil capital's appetite for bloodshed. The Symbol of Peace All Might had famously fought to protect was shattered from within as dark hearts rose in power. As the detention center had started to ransack due to chaotic situation. Izuku is completely clueless on what was happening outside and inside the facility, until two dark shadowy entities suddenly appeared to him and casts a warp quirk to offer him the most powerful weapon ever created and will use as destruction.

With the escape from solitary now approaching towards the U.A which he used to dream about studying and training to become the greatest hero. With fully equipped villainy costume and a mask he looked around the campus before closing his eyes and took a deep breath… that was the kind of chaos he wanted and dreamed of. Some came to kill him, while villains believe he came to rescue and aid the League of Villains.

But Izuku unleashed chaos upon them all! He refused to be a pawn in someone else's game. Killing and blasting both parties with his whisper gun. With satisfaction, the true purpose of coming to the U.A was to track, confront, and kill his old childhood friend…..
