Let's start with Amumu; the sad mummy:

Amumu's lore casts him a sad little boy who wants to be around people. How does his kit make this happen? For starters w and e effect this by making you want to be near people, you fulfill amumu's need by constantly stick around as many people as possible, maybe even focusing your affections on just one person *coughADCcough*.

His ultimate on that note is the strongest extension of his desire to be with other people. The curse of the sad mummy is that you're forced to be with him regardless of your will. You will suffer his despair and tantrums.

What about his q then? I think his q is his best skill, because as players we especially feel what Amumu must feel. If we can land this q, people will be near us.We'll have some friends! We feel the disappointment when we miss the toss and I can only imagine that Amumu would feel the same.

I think the only lore trade off for gameplay is on his passive which really just serves to make him a harder to ignore target (though one can argue that that's an example of lore also)

Draven's lore casts him as Draven.

He and his kit fulfill this nicely by being Draven.

Nautilus's lore works greatly with his kit.

He is basically a hulking mass of sorrow. He is no longer who he once was, he is but a mere shell of his former shelf, a very strong shell. His kit is very symbolic of what he truly wants. Wanting to take people down to the depths with him.

His Q pulls them into him, dragging them down into the depths alongside him. While his W projects the wrath that he wishes to unleash on his enemies. His passive snares the enemy into the ground, while his E slows them preventing them from getting away. And finally his ult sends a wave knocking the enemy up into the air and stunning them so that they will not resist and join him in the depths.

Nautilus will pull his enemies down into the depths with him, so that they too know what it is like to be left behind.

TLDR: "Drag them down" - Nautilus

well thought out OP

Ok heres my try, taric is fabulous guy whos all about helping people

Q-tarics desire to share his fabulous enery with his friends causes him to emit a fabulous green light that invigorates and heals them

W-taric's fabulousness is too much for him to handle and it bursts causing him and his enemies to become less fabulous (their clothes are tattered aka less armor)

E-tarics desire to share his fabulousness even with his enemies causes him to shoot a fabulous projectile that dazzles his enemies, leaving them stunned

R-taric has had enough, he is fabulous but he wants to take it to the next level. He explodes in a series of fabulous lights that his allies cant help but be impressed by causing them to fight harder for taric to impress him

Kog'Maw (Another one from me)

He wants to eat.

Q- He spits out his spittle of acid so that he may better chew his food.

W- His meals are not allowed escape, Kog'Maw fires the goo from his mouth at long range to chase fleeing enemies.

E- Some enemies like to be fast so Kog'Maw hurls out a trail of vomit to slow them in their tracks.

R- Firing large bolts of acid into the air, Kog'Maw refuses to let his food ever escape him.

In the words of Kog'Maw "Keep coming, not full!"

Teemo's kit is designed to f**k people off as much as he possibly can

His q is a blind, "LOL u cant c mi!!!!!! jajaja!!" - Teemo
His w is a speed up so he is so fast. you are completely vunerable to him being able to run up and shoot a f**king dart in ur face then run away giggling and chirping liek the little prickface he is
his e is poison to compliment him being able to run up and hit you once leaving you poisoned and groggy and fuming with hatred to the little fking c*nt
his r are invisible mushrooms that explode in your ****ing face if you come close. they also slow you so he can prance after you shooting you in the f***ing back with his f***ing litle darts while you die from the mushrooms and his poison


f*** you teemo

Brands kit is designed to destroy the world through the use of fire. He accomplishes this by having every skill involve fire, 3 of which are AOE and his passive which gives a burning effect.
