Kassadin was released all the way back in 2009. He's basically an old man within League of Legends, and if we're honest, he's an old man in his lore as well. He has managed to walk the Void, a changed man forever. Previously he was a mere father from Shurima, but when his daughter was taken by the Void he ventured into the vast nothingness to try and find her.
Now, if that isn't a tear-jerking story, then I don't know what is. Sure, Kassadin's lore has been changed over the years to fit the narrative Riot is going for, but the current iteration would make for an insanely great movie. Just imagine Kassadin using a Void-cellphone calling Cho'Gath like: "I will find you... and I will kill you." I mean... I would pay to see this movie any day... wait I've just been informed that these lines have already been used in a film before... RIP, guess I'll have to think of other menacing lines... maybe him meeting Kai'Sa again and going 'I am your father' would be a good line. Wait, that one is already taken as well?!
Okay, guess we will have to strike out the brilliant idea of a Kai'Sa and Kassadin movie in the future. All the good one-liners have already been taken by other movies. So, if we aren't getting any news on an Arcane season 2, the League of Legends MMO or this Kassadin and Kai'Sa film I just made up, then we have to check out some Kassadin skins. Which ones are the best Kassadin skins and what do they look like? It's time to get into the universe hopping mobile and check it out!
