Tahm Kench aand...Gnar?
So, the subtext of Tahm Kench is that a Bilgewater gambler (named Tahm Kench) was consumed by his own metaphorical "hunger"/greed and transformed into the current Tahm Kench, an entity that has had many other shapes and names before.
Then there's this thing between Tahm and Yordles being rivals, which has yet to be explained.
Far-fetched as it is, it struck me that there's one among the Yordles listed as his rivals that has something faintly in common with our dear catfish-man; Gnar. Namely, **he transforms into a creature preoccupied with a vice-like emotion. **
Tahm Kench is supposedly very old, so he's certainly not a new phenomenon; Gnar was preserved for a long time, so at least time allows for their conditions to, in theory, share a common origin. Gnar's transformative condition has never been explained either.
So what do you think? Is Gnar possessed by a Tahm-like demon, or is that too far fetched?
seems to present a similar manner, only that he's a monster because he simply is a monster. There is a slight chance that Gnar may have been possessed by his own anger in order to mutate into the Mega Gnar
he will always be, but for now, rest assured, it is in his Biological Genome that makes him the cute (yet crazy monstrosity) he really is.
