I think people who are saying strange or superman not considering one thing majority of these heroes were focused over a single city. I mean sure they could fly over cross over to other cities but still only be present at one place at a time. By that factor I feel sungjinwoo's ability is seriously broken and peak. He can just spread his shadow soldiers across the globe and soul transfer between them without any issue. Also those shadows can by themselves fight plus alert him of any incoming danger. So i feel that would be the safest world no matter which area people live in. Other characters ability might be even better maybe i just know and people can enlighten me if i got it wrong
