It's likely that three would be caught. I knew I forgot something shit sorry

Spinister and Tony Stark would capture one should they pursue the sound in the shadows.
Steve and our ol' pal Winter Soldier could capture one as well.
Naoto Shirogane and Kanji Tatsumi as well.

All of them would notice their shadows have disappeared for a brief time, and will return to normal upon the conclusion of the event.
