Who will win in an actual fight (lore) Zhask or Yve?
Zhask kept running and Yve keeps chasing him. No one knows who's in a winning fight, but in terms of their actual power, scale, magic and capabilities, who will actually win the fight? An MLBB movie about this would be so good.
If they actually fought 1v1 I think Zhask would win. Zhask kept eating and destroying countless planets with his swarm (in his lore) and Yve just kept destroying his swarm but could not completely be wiped out as stated by the lore.
Also, don't forget about the fact that if it weren't for Yve (and her race) that keeps chasing Zhask, Zhask would've (imo) actually conquered the whole universe.
So in my conclusion, Zhask would win the fight if they're both prepared. Zhask is weak without his swarm but Yve is strong when Zhask is unprepared. If Zhask and his swarm (The Ultimate Bug on Zhask where there's countless nightmaric spawn ultimate, which I imagine actually would work in lore) were to fight Yve, she's cooked.
