They have Pentakills before the game starts.

If you want answers based on real data, these are statistically the top 5 champs when it comes to average number of kills per game. Which of these is "easiest" is a matter of opinion.
Kat's pentakills require the least planning, since you just shunpo in at the end of a fight, press R and hope for the best. Zed's pentakills are the least risky, since he has the lowest average number of deaths out of these 5 champs. Talon's pentakills have the least counterplay since they can be almost instantaneous out of stealth if he is fed enough. Like I said though, whichever is "easiest" is a matter of opinion.
I'd personally say Zed appears easiest, since he's the only one of those that starts off at around 50% winrate for first-time Zed players. All of the others require practice/experience to hit 50% winrates with.

kappa
and why not Pyke? Very lot of movement and killing R!
if they group a lot as five.
the movespeed steroid after she gets at least one.
resets on his ult(if the whole team is weakened from a fight and in execute range)
mobile high damage but need to be fed or scaled late.
can also get penta.
He is OP

Rengar
ad 
How did Teemo not make the list? Guy could be dead for 15 seconds and get the Penta.
I have to say its Kog'Maw late game. However, Rengar is VERY good at getting pentas. I almost got one with him, but my lux ulted the Diana. :P I have never actually gotten a penta, but Kindred is also very good at getting pentas, plus she can just ult and save herself.

to get a lot of pentakills in other champs you need to have at least 1 pentakill at this champ
