Have it to where the champ you are playing as will comment on the progress towards the penta. If you get a quad, and then miss the penta, they'll get annoyed and say something along the lines of, "Maybe Next Time", in their own unique ways. If you GET the penta, they'll celebrate in their own unique way.
If anybody comes up with anything, put it in the comments!
Edit 1: Holy smokes; I did not expect this to get so much attention, keep the ideas coming guys!!!
They underestimated the power of the Watchers.
Wasn't that hilarious!?

That will be the last time they underestimate Shurima.
They opposed the moon. Now they lie slaughtered!
Demacia is victorious this day!
Hah hah! Who needs a weapon to be the champ?
Just another day, and 5 more casualties.
They won't be getting up anytime soon.
Now this is a true hunt!
Freljord's new queen has spoken!
Never... enough... MY THIRST IS UNQUENCHABLE!
Five new bounties to collect. I'm gonna be rich.
Outsmarted and overpowered! Your moves are predictable!
My power... is INTOXICATING!
I'm going to need to clean my blade after that one...
THE BANANA COMPELS YOU!
Royal Flush, hands down. Heh heh.
So many souls, so many flavors... heh heh hah...
That's the last time you'll underestimate me!!!
Your bodies crumble like dust. Your forms are inferior!
How sweet. 5 chalices to drink from.
Better bring more friends next time. Hmph.
5 more graves for me to dig.
The shadows have struck down our foes yet again.
I saw this coming a while ago.
I do miss Dawngate doing this; one of my favorite characters was Ashabel, and I still remember her double kill line.
'I charge extra for multiple partners.'
How about it would play a penta kill theme music? Que the drum solo!
i really like this idea rito should do this.
told you i was on duty
the cards never lie
well that was easy
maybe i punched them a little too hard
the song of death is complete
i am perfection
Definitely a good idea.
This would be really out of character for some champions, lol.
they would have to voice two lines for every champion
its not going to happen
its cool but not gonna happen.
