Which champion is the scariest when fed?
My gut says either Akali or Draven.

katarina "just cc her" yeah that's easy when my projectile is still in flight by the time I get instantly bursted by her ult

Everyone lol.
A good Vayne player.
As an ADC player I vote 
Rengar can be beaten with teamwork easily.

all assassins. except evelynn or something. also someone like darius can legitimately go 1v5 and win fights if fed
You've never fought a snowballed eve.
i have. shes terrible at what she does. becomes much more useless than any other assassin a lot faster.

Among friends, we use the term 'raid boss' to describe that rare instance where an enemy champion is both the primary damage-dealer and the tankiest person on the team. This is almost always the result of a good Nasus or Shyvana getting fed. Kayle can also be terrifying if fed - She hits hard and is capable of healing, chasing, and turning herself or others invulnerable if you try to focus them.
If your team is squishy,
. There can be a million of you, but so long as he has enough damage, he can delete you all.
Draven, Vayne, Zed, then an assortment of other assassins, ADCs, and mages.
Fizz.
tfw he has black cleaver and gets the reset at the start of a fight
I vote Fizz as well. Fed adc and mage/assasin can be bursted down as long as one cc lands. Fed fighter can be difficult to deal with but there's still room to fight back or at least run away from.
Fed Fizz with 45% cdr? Troll pole, zhonya, troll pole, u dead without being able to touch him or peel him off during that entire process no matter how many of your teammates were present.
