Pentakill is Valoran's most famous (and possibly only) metal band; its name a homage to the act of scoring five kills within quick succession on the Fields of Justice. It is also a series of alternate future/universe skins in League of Legends, featuring champions as if they were part of a metal band.

You have sown. Soon you shall reap.
You have seen the true voice of metal fall quiet, surrounded by the massed harmonies of your weak whispers. But listen closely to those whispers, and you shall find the seed of truth.
Five Four voices. Five harbingers of destruction, waiting patiently for their time to rise. And on that chosen day, these five shall change your world forever. Sonic brutality has never ascended such heights before. These voices have already slain the Dragon and butchered the Baron. They have ravaged the Fields of Justice, burned Runeterra to the ground, and slaughtered millions of Teemos. When they come, their breed of metal shall smite your plebeian souls and punish your frail bodies. You will cower at their visage and tremble at the name... Pentakill.
And Pentakill is coming... for you. Because you have sown, and soon you shall reap.
"MY RIG DOESN’T JUST HIT ELEVEN. IT ******* MELTS ELEVEN."― Pentakill Mordekaiser
A prodigal guitarist just minutes after his birth, Mordekaiser spent his formative years mastering the art of metal until he was so adept at shredding that his guitars would wither and combust under his furious fretwork. Desperate to find his instrumental equal, Mordekaiser traveled far and wide in search of a legendary guitar known only as "Numero Uno". Both made of metal and made for metal, Numero Uno was known as the indestructible axe, a tool Mordekaiser hoped would withstand his beastly playing. Finally, after years of searching, he found it, buried deep within a Shuriman crypt. But as Mordekaiser grasped the instrument's neck for the first time, it too grasped him, filling him with murderous intent and driving his headbanging instincts harder and heavier than they'd ever been before. Mordekaiser emerged from the crypt a changed man, and as he returned to civilization, his antics took a turn for the violent. One fateful band practice, Numero Uno's power became too much - Mordekaiser turned berserk, murdering his bandmates, including their up-and-coming singer, Karthus.
"Come what ever may, I’ll be the death of you."― Pentakill Karthus
Pentakill Karthus was not born, but reborn. A promising metal vocalist in life, the demons of the Shadow Isles saw purpose in Karthus, and after his murder at the hands of Mordekaiser, imbued him with undeath before steeping his voice in the fury of countless lost souls. Karthus resumed singing, earning himself a fearsome reputation after eating a live poro and gargling gravel during his Shadowstock debut. He set about establishing himself as the Shadow Isles' finest vocalist, but soon grew tired with the lack of local instrumental talent. Remembering Mordekaiser's unmatched playing, Karthus sought passage back to Valoran, and enlisted the help of the only musician Karthus felt was his equal: the bass-playing ferryman, Yorick.
"MORE BASS. TURN THE BASS UP. TURN THE ******* BASS UP. MORE. MORE."― Pentakill Yorick
Pentakill Yorick spent his early years on the Shadow Isles torturing ghouls and ghosts with his pounding bass playing. But as the years passed by, the ghouls started to enjoy the head-rattling virtuoso's playing. Eventually they formed Yorick's hardcore fanbase and followed him throughout the Shadow Isles, earning him the nickname "Brown Note" thanks to their muddy coloration. After ferrying Karthus back to Valoran, Yorick decided to join him, create a “******* awesome” band, and unleash their terrifying symphony on the unsuspecting living masses.
"...!"― Pentakill Sona
After arriving in Valoran and reuniting with Mordekaiser, the three headbangers scoured the lands, butchering all within ear's reach with their demonic tunes. But they met their match in Sona, who, through years of silence had attuned her hearing to withstand all manner of metal. Impressed with both her resilience and her ability to tear up her keys while covered in blood, the three offered Sona a place in their band, and thus Pentakill Sona was born. With her in the band, the group's destruction amped up significantly, and soon only the frozen northlands harbored humanity's last stand. The monolithic colossus of metal that is Pentakill was almost complete...
"GET ME A NEW CHINA, TOMS, SNARE, DOUBLE PEDAL, AND COWBELL. YEAH, BASICALLY A NEW SET. OLD ONE BROKE. CAUGHT FIRE. YEAH I SET IT ON FIRE."― Pentakill Olaf
Continuing their massacre, the demonic quartet finally reached the frozen wastes of the Freljord. Tribe after tribe fell, the Howling Abyss howled for mercy, and villages were set ablaze until the whole world was ready to burn. Looking for a celebratory drink, the four entered Runeterra's last standing bar, and found it empty save for one man. Olaf was not in a sober state, and challenged "the biggest of yous *****" to an arm wrestle. Yorick stepped up, and the duel began. Legend states that the two were locked in arm-on-arm combat for days, sustaining themselves with whiskey and peanuts. Finally Karthus, bored of the deadlock, offered Olaf a place in the band. "I’m only good at hitting ****", said Olaf. "Perfect", rasped Karthus, "you shall be our drummer".

The Master of Metal
Jace P. Prest reporting from Zaun Down in the slums of Zaun, where the gutters glow green with techmaturgical runoff, one can find all manner of unsavory characters: the disreputable, the disadvantaged, and the disillusioned. These are the homes of back-alley sorcerers and shimmer addicts, all those whom critics say are the byproducts of Zaun's rapid and reckless research initiatives. Yet, despite (or perhaps, because of) the many negative images associated with the Zaunite slums, thrill seekers frequently venture down to these dark alleys. They come in larger numbers every week, and all come for one reason: the undeniable allure of Zaun's underground techmaturgical music scene.
With instruments powered by techmaturgical amplification, "Techma-Tune" musicians and their strange, wailing sound have been gaining ground in Zaunian taverns for years. Those hip to the scene gather in droves to listen to the stylings of bands such as "The Hexbenders", "Yordle Mothership", or "Tainted Nexus". For the price of a cheap (and questionably concocted) beverage, any traveler can shove for shoulder-room to see these talented groups perform.
Though the Techma-Tune movement has long been an unknown scene outside of Zaun, a new star recently pushed interest in this genre of music beyond Zaun's borders and into the hearts and minds of countless Valorans. For the past few months, Mordekaiser, the Master of Metal and champion of the League, has been storming the stages of Zaun with devastating effect as lead guitarist of the band "Pentakill". His dark, pounding rhythms resonate deeply with his followers. One fan says, "His strings speak to the torment of my existence." Another gushes, "I know that deep beneath that armor beats a broken heart like mine. I love you, Mordekaiser!"
We had the privilege of speaking briefly with the League fighter and night rocker:
JP: Mordekaiser, you're an enigma both in and out of the arena. What draws you away from the Field of Justice to pursue this surprising side-project?
M: My fans. I am drawn to their disease.
JP: You mean their feverish love of this Techma-Tune music?
Pentakill's popularity exploded recently when Mordekaiser appeared on stage with an unlikely co-star: Sona, the League's darling diva! The masterful mistress of strings has been regularly rocking at Mordekaiser's side in true Techma-Tune style, clad in silver chains and black finery. The two have been busy releasing more captivating singles than ever before, with Sona's otherworldly serenades adding a somber and captivating undertone to Mordekaiser's gritty, powerful chords. Though Sona was (understandably) unavailable for comment, Mordekaiser has confirmed his desire to expand the ensemble further into a full band: "I would welcome those who would bring my music further power. We are known as Pentakill, and we shall rock as no other. Join us, if you are so bold."
Hear Pentakill perform their new hit, "Mask of Madness" at Trogsworth's Tavern in the heart of Zaun’s trade district any night this week. Be warned – it's standing room only and the crowd can get a little raucous. Also, if you yourself are a talented techma-musician, gather your courage and approach the stage afterwards for a personal audition!
Journal of Justice's Letter
"Dear Pentakill: As a new summoner, I have been hard at work training, working with several champions who share my style. One such champion, and the frontman for the band Pentakill, is the master of metal himself: Mordekaiser. Although he has joined forces with the musically talented Sona to make a band to bring the life-changing music of metal to the League, it confuses me that there are only two members: guitar and keyboards. After giving it some thought, I would like to ask the frontman himself if he has any plans at all for additions to the band and what new heights he has in store for them?" – Lemarius 
Getting a backstage pass to a Pentakill show is perhaps the next most difficult thing to getting to interview champions after League matches. Nonetheless, I fought through legions of spiky, thrashing Pentakill enthusiasts to get you Mordekaiser's response.
"Pentakill is recruiting. We get lots of applications. One new member is coming soon. You will all suffer his brutal wrath."
I’m afraid we've got some bad news. Our lawyers just informed us that Karthus has received a drunken disorderly following our last 18 concerts, which is news to us because we just found out that's an actual crime. Unfortunately, this Demacian judge is a real hardass, and the only plea deal he's offering requires us to assign Karthus a "sober companion" to keep him from relapsing. We tried to explain that anybody who gets between Karthus and the keg usually winds up dead, but he keeps insisting. Besides, sending Karthus to jail would mean canceling the tour, and we're already in the hole since Olaf burned down that hotel in Piltover because the concierge insulted his hat.
I guess we’ll have to interview some candidates. But first pass me that bottle of Jarvan Walker. I haven’t had breakfast yet, and there’s no way I can make a decision like this on an empty stomach.
Karthus: I can't believe you $#*ing guys are going make me quit drinking. I mean, what would I do without booze, huh? You can't really expect me to do this sober!
Mordekaiser: Karthus, you really have to see how you've contributed here. It isn't our fault you can't hold your liquor – you haven't got a stomach. Besides, you were going strong until you took those six hits off Sona's . I could understand if you were the support, but that's just irresponsible. Tell him, Sona.
Karthus: Hey @#$& you, you ^$*ing #$*@s! I !$#^ing carry this %&^*ing band! Who the *&%$ing @!#$ do you &%#$s think you are making me get clean? @#%^ing %^&# this $%#@, I'm going to @%^$ing kill whoever you @#^$ing hire and then drink vast quantities of mead. @#%#!
Olaf: Well, I don't think anybody's going to top that. Um… our new record, Death Rides a Pale Boar is in stores now. And don't steal it because, you know… we'll kill you.
