Who is the champion that is hardest to kill when fed?

We all know getting that juicy bounty is what we all want but sometimes it is so hard even when you gank a certain champ.

for you guys who do you think that champ is?

a common answer could be malphite cause he as r but once its down i feel like he can be killed quite easily not sure.

My other answer would be zac. He has tons of damage for a tank, tons of healing, engage, disengage, slows, knock up, and a passive that gives immortality so u basically have to kill him twice. not only that but a for a fed zac you will need to build anti armor or magic pen as well as anti heal. he basically has almost everything that you could want.
