I like to imagine Singed and Viktor as friendly rivals

Both have the same thing in mind, progress no matter what the cost and to create the ultimate being, to reach the next step in the human evolution. One does it with techmaturgy while the other one uses genetics and alchemy.

The thought of them regularly checking in on each other's work too see how far their rival is at this point or sometimes proudly showing off their own creations is just awesome. I imagine Singed being shittalked by Viktor after he created Blitzcrank while every of Singed's subjects died during his experiments, then, some months later, Warwick roams the streets of Zaun and Singed shittalks back.

I'd love it if this was canon. It would add a lot of humanity and empathy to these characters that otherwise seem somewhat cruel, well Singed at least.
