He has become indestructible.
Warhammer revealed and more.
Ok,I over looking this but:
Billy:"Marley needs another Heros"
Billy extends his hand to Theo(Maggath)
We see Zeke in the next chapter
So is this sentence implying that someone may become a new “heros” to Marley? And the panel focus on Theo and Zeke,either Theo will become a new “Heros” or Zeke will.
Zeke’s apparence maybe just to connect to Eren’s letter,but what if this is actully making a “foreshadowing” to the fact that Zeke may become a hero to Marley(maybe he will become a martyr) and Marleyans may look Eldians with a better point of view?
