Can you guys name some hypercarries?
I just want to know a few champs that are classed as 'hypercarries' because I feel like buying one.

Isn't a hypercarry someone who can walk into a 1V5 and survive? They would just get melted if they did that
There isnt exactly someone who walks into a 1v5 and survives....
Not... quite.
Hypercarries scale super hard into the late-game, usually with high dps thanks to AS steroids or defense mitigation. They sacrifice early game burst to do so, and thus are weaker to lane bullies (with some exceptions).
Some champions can 1v5 if they're fed I guess, but that's not the qualifier. That's just being really good.
Any champ you get 20 kills in the first 15 mins of the game + 148 farm while building bruiser items.
