Something I'd Honestly Hope to See With the Mordekaiser Rework (@MaliciousMetal)
So for a while now I've had an idea on what Riot should do with Mordekaiser, largely inspired by another villain who should give off the same feeling; Thanos. Mordekaiser really should be Runeterra's Thanos; an immensely disturbing and powerful behemoth of a man with some aspects that 'humanize ' him. Not humanize him in a sense that Mordekaiser should be given a complex array of emotions and feelings, but more add details that remind us that he was once a man, and how disturbing it's carried over to his unnatural afterlife. For instance, perhaps give him disturbing and dark 'family values' just as how Thanos treats his Black Order like his 'children.' The best example I can think of this working with Mordekaiser is having him be the ex lover of LeBlanc; and allow me to explain. LeBlanc betrayed Mordekaiser as his closest advisor, leading to his ultimate downfall. If she was close, it'd be an interesting dynamic to see Mordekaiser treating LeBlanc not with hatred, but with somber and creepy disappointment in someone he once loved. Along with that, it can add an interesting dynamic with his return, perhaps LeBlanc can still hold feelings for him? And Swain's now gotta deal with 'the guy she tells you not to worry about.'
tl;dr: Make Mordekaiser like Thanos and have him be LeBlanc's exlover
