Oh that where riot got the champion quote from

So I saw the trailer of this movie Jem and the holograms and saw a lot of backlash on it. I was like why is everyone so mad and then I found out it was based on the cartoon series. So I type on youtube and I found this video: [ https://www.youtube.com/watch?v=IWVhIQ8KgN8]

Then I was like I heard this song before but in reality I didnt I just heard the lyrics before. A particular champion said it do you guys know who it is?

Its crazy I was playing league of legend and then I took a break and saw this and now I am back to league of legend.
