Mundo's lore has a plot hole so big that it ruins the story.

"By his teenage years, his parents were nowhere to be found. By the time he had legally acquired his license to practice medicine, he had been acquitted of thirty-eight separate charges of murder by the Zaun authorities; the lack of evidence made prosecution impossible."

Not having enough evidence for a conviction is one thing - that happens all the time, even outside of Runeterra. But the idea that people would do nothing is simply preposterous. Being acquitted means that, although they may not have had concrete proof to tie Mundo to the crimes, he was under frequent, heavy suspicion. What was his attitude to the repeated attention from the authorities, I wonder? Did he display shock at their accusations and disappointment in their lack of faith in his innocence? Or did he rub it in their faces, skirting the thin line between caution and confession?

The scale of his "alleged" crimes makes the reactions of his victims' acquaintances downright anomalous. One murder victim's family may trust the rule of law and accept that the suspected murderer was not convicted. But so many murders, and all perpetrated by the same person? After a while, the whole town should eventually have risen against him (possibly with torch and pitchfork) to exile him or kill him - even just one crazed vigilante would've given the story some grounding. There's a limit to how often people will say, "well, we can't find a murder weapon and he says he was nowhere near the scene of the crime, so we'll let him go as soon as he stops pointing at us and laughing."

That isn't believable.

If nothing else, I would expect there to be a counter-Mundo champ: perhaps someone who lost too many pets and family members to Mundo to abide the incompetence of Zaun's court system and now seeks to execute Mundo for vengeance and justice.

Or just fix the plot hole.

Read his lore, the second paragraph, where it saids the city state of noxus looks at this as a good thing and not inhumanity

He grew up in Zaun, not Noxus.

Ever think that the multiple counts were a family breaking upon his cleaver? As in, he killed one guy, and then a series of people looking for revenge.

Given that a lot of it happened before he became a muscle-bound mad scientist, that doesn't work either.

Mad scientist. Zaun looks approvingly on PROGRESS.

Unofficial motto is 'The ends justify the means'. Mundo does just kill for fun, although it is the primary goal. His kills advance science. Zaun isn't a haven of Justice.

Also as a scientist, you think he isn't ready for things like....mad relatives? He probably has chemicals to stun invaders of his lab and then he can test on them. He's crazy, not stupid.

So, with all the recent lore reworks, could we get a Mundo lore rework that at the very least makes a bit more sense than his current one?

Zaun is a very volient city-state, chances are with every murdered victim there are hundreds of suspects in Zaun. So facts are Mundo most likely doesn't even stand out from the crowd of criminals of Zaun.
