Galio seems to be the saddest League character now.

Outside the gleaming city of Demacia, the stone colossus Galio keeps vigilant watch. Built as a bulwark against enemy mages, he often stands motionless for decades until the presence of powerful magic stirs him to life. Once activated, Galio makes the most of his time, savoring the thrill of a fight and the rare honor of defending his countrymen. But his triumphs are always bittersweet, for the magic he destroys is also his source of re-animation, and each victory leaves him dormant once again

It means that this guy is constantly alive but unable to move when there's no wars that implies magic near Demacia. I feel really bad for Galio now, can you just imagine how horrible it is to see people you've met, grow older, days after days, years after years, decades after decades, making them eventually forget you and see them slowly dying while the only thing you can do is watch? He is so f*cking alone now. The only time Galio talks about it is with Poppy, which by the way is the only person he knows:

I like you, little blue person. You're the only one who doesn't change.

This makes Amumu's "sad" story kind of laughable.
