RengarRengar is a ferocious vastayan trophy hunter who lives for the thrill of tracking down and killing dangerous creatures. He scours the world for the most fearsome beasts he can find, especially seeking any trace of 
Kha'Zix, the Void creature who scratched out his eye. Rengar stalks his prey neither for food nor glory, but for the sheer beauty of the pursuit.
Lore
Rengar was born to a tribe of east-Shuriman vastaya known as the Kiilash, whose society venerated the honor and glory of the hunt. Rengar was born the runt of the litter to the tribe's chief: a Kiilash named Ponjaf. Ponjaf believed Rengar's diminutive size would make him a worthless hunter. He ignored his child, assuming the runt would starve to death.
The young Rengar fled the camp, ashamed that he'd disappointed his father. He subsisted on grubs and plants for weeks until one day, he was nearly killed by a legendary human hunter named Markon. Upon seeing Rengar's state, he took pity on the creature and let it live. Besides, this was no mighty vastayan warrior worthy of Markon's blade.
Rengar spent months following Markon, feeding off the corpses the hunter left behind. Rengar still hoped to one day rejoin his tribe, and so took great care in observing how Markon took down his quarries.
After some time, Markon grew sick of the pathetic Kiilash following him around. He put a knife to Rengar's throat and informed him that the only way to be a hunter was to hunt. He tossed Rengar the blade and kicked him down a ravine, where he was forced to make his first kill to survive.
From then on, Rengar spent years pushing himself almost to breaking point. He scoured Shurima for the most powerful and dangerous prey. Though he would never be as big as other Kiilash, Rengar was determined to be twice as ferocious. Over time, instead of coming back to his camp each time with fresh scars, he began to come back with trophies: he polished a sandhawk's skull to a sheen, he braided the teeth of a shrieker into his hair.
Then, when he decided the time had come, Rengar returned to his tribe, ready to be accepted as a true hunter.
Ponjaf scoffed at Rengar and his trophies: he decreed that only by bringing back the head of an elusive Void abomination would Rengar be welcomed back into the tribe.
Blinded by his eagerness to return to his tribe, Rengar allowed this wily beast to get the 
drop on him. The Void creature ripped out one of Rengar's eyes and escaped.
Furious and defeated, Rengar admitted his failure to Ponjaf. As expected, his father chastised him.
As Ponjaf spoke, Rengar noticed all the trophies adorning his father's hut were dusty and old. The tribal chief hadn't hunted anything in a long time - he'd likely sent Rengar after the Void creature because he was too afraid to do it himself.
Rengar interrupted his father and called him a coward. Many Kiilash were blessed with strong bodies or comfortable homes. Rengar, conversely, was born facing death. He had taught himself how to hunt, and had the trophies - and scars - to prove it. Even his own bloody eye socket was a trophy - proof that though Rengar was born with disadvantages, he never gave up.
Rengar leapt onto his father and gutted him from neck to belly. The fiercest hunters of the tribe crowned him in flameroses, marking him as their new chieftain.
But Rengar didn't need his village's acceptance. All he needed was adrenaline pumping through his veins as he chased down his prey. Rengar left the village, without pausing to take a trophy from what was left of Ponjaf - the chieftain was not worthy of remembering. Instead, he set off determined to find and kill the Void creature that had tried to blind him.
Not to satisfy the village, but to satisfy himself.
- Prey
- A predator feasting on fear. A hunter without any. Only one will make it out of this alive.
Rengar smelled the blood before he saw the dead humans. Six or so, he estimated, but it was tough to get an exact count thanks to the number of pieces they'd been torn into. Their swords were strewn about the meadow, as useful as dulled cutlery.
He knelt, licking blood from the ground.
Cold to the tongue. Still sweet, yet bitter with the taste of iron.
It had been spilled less than an hour ago.
Turning over one of the stray limbs in his hand, Rengar found a line of greenish saliva dangling from where the arm had been ripped from its body. He raised the stump to his nose and sniffed.
The saliva smelled foul, like a corpse that had rotted in a puddle of excrement. Just raising it to his nose nearly made Rengar want to vomit, and he had a stronger stomach than most.
He smiled his wide, toothy smile. The creature who inflicted these wounds would be easy to track.
Rengar watched from the 
brush as the razorhide worked its claws around an old man's skull and crushed it between its boneteeth. It howled in disappointment, evidently unimpressed by the lack of a crunch.
The giant, four-legged beast stomped through the elderly man's tent, crushing it with a single step, then biting at the canvas and tearing it apart.
Tossing aside the man's bedroll, it howled in delight as Rengar heard the scream of a young boy.
Little one.
Frightened. Good fear. Delicious fear.
Time to eat. Time to silence screams. Time to---
Pain.
Pain on the back of its neck. Sharp and hot. Something bit it? No. Another pain, then another. Sharp stabs. Something with a weapon. Something with some fight in it.
Maybe something tasty.
Rengar held onto the 
kirai saber with one hand as the razorhide bucked back and forth, trying to dislodge him. With his other hand, he grabbed a knife and punctured the beast's leathery hide over and over. He knew he'd never kill the beast this way, but he'd get it bleeding. Confuse it.
With any luck, panic it.
The razorhide dropped to its stomach and rolled over, taking Rengar with it. It was fast - much faster than Rengar would have thought for a creature of its size. He barely had time to dislodge his blades and jump away.
The two combatants got to their feet. Blood trickled down the razorhide's scales, each one sharp enough to sever a limb. Combined, the scales made for a nigh-impenetrable defense and a thousand small weapons, all at the same time. It circled Rengar, sniffing the air. Rengar could tell he'd never win a straight fight against it. It was too big, too quick, too strong.
A lifetime of scars had taught Rengar the secret of hunting: it wasn't about being strong. It was about knowing when to withdraw, and when to attack.
Right now? It was time to withdraw.
He sprinted away from the village, toward the tall grass surrounding it. The razorhide leapt after him in pursuit, its feet pounding the earth. Rengar could hear it behind him. He could be hidden in the grass soon enough, but the razorhide would catch up to him long before then.
He just needed a few extra seconds.
One-eyed vastaya will be delicious. Only one thing tastier than something young: something that just tried to kill you.
Stomp the cat-beast to death before eating? No. Better to swallow him whole, feel thrashing grow weaker and weaker until it deliciously stops.
Unhinge jaw. Bite down, feel warm spurts of blood---
Tripping. Falling. What?
Some sort of weapon - three 
balls, tied together with leather - tangled around legs.
Bad.
Still. Broke free easily. But cat-beast gone. Only slight rustle in tall grass to show where he went.
Bound into field after it. Cat-beast: small, scared.
Me: big, fast.
Will stomp all tallgrass down if it takes---
Pain.
Warmth running down hind legs. From where? Behind?
No cat-beast. Ran away again.
Pain. New pain, in side. Annoying. Not problem. Just annoying.
Start running. Doesn't matter which direction. Put distance between us. Regroup.
Turn around. Where vastaya? Maybe ran away. Maybe hiding, waiting.
This was the best part. Invisible within the tall grass. His prey cautious, but not smart enough to be terrified.
The momentary silence before the attack. Before the quarry realized just how helpless it was. Before the howls of pain, and the blood, and the adrenaline, and the joy.
Rengar threw his head back and 
roared.
Where roar coming from? Sounds like everywhere. Not roar of anger. Not roar of fear.
Excitement.
Getting closer.
No. This was a mistake. Out in the open. Run. Run back.
Hard to breathe. Why?
The wound in the side. Deeper than it felt? Throat wet. Choking. Blood.
Don't slow down.
Where is village? This way? No. The other.
Vastaya still roaring. Still getting closer.
Run. Doesn't matter where. Just r---
Flash of metal. Cool air blowing on stomach.
No, inside stomach.
Feel self growing lighter. Sound of something wet and heavy hitting the ground. Many wet and heavy things.
Look back. Guts. Fluid. A trail of red and green.
Pain. Stinging pain, throbbing pain, stabbing pain. Everywhere.
Can't stand up. Legs buckle. Breathing hard. Hear footsteps coming closer.
Sound of knife leaving sheath.
Feel something. Something new. Something terrible. Not hunger, anger, joy.
Fear.
Rengar approached the prone razorhide, its feet still kicking at the air as blood poured from the massive slash across its belly. Its eyes were dilated.
What trophy would he take? The skull? The mane?
The creature lifted its head and worked its jaw, biting at the air out of anger or confusion.
Rengar smiled. The creature's boneteeth were sharp. Smooth.
One of those would make an impressive addition to his 
necklace.
