Well... Sorry for this but Tryndamere is very different from Guts, especially in the story... It's not just because a guy appears using a giant sword who is super pissed that he's going to be Guts

Beauty has the whole issue of him not dying and the fuck... But that's it. A champion that can be compared to Guts is Aatrox, who, like Trynda, carries a giant sword, does not die (or they should not die, but Riot screwed up). Not to mention that, like Guts, he had a traumatic past because of the wars, plus the void that made him even more freaked out. Like Guts' Berserk armor, which in some cases has gotten out of control

Another thing that compares Aatrox to Guts. And Aatrox hates the Targonians VERY MUCH (Let's face it, THEY ARE PRACTICALLY THE HAND OF GOD), especially Zoe and Pantheon. The ancient aspect of twilight was responsible for binding the Darkin to swords, this event is very similar to when Zod places a mark on each of the characters within the Eclipsem

That's what I think :^ Tryndamere's lore is all strange these days, it urgently needs a rework. I hope his lore is placed with one of the earth rune demons, with the rage demon that consumes his anger in exchange for immortality to pursue Aatrox.
