Tchalla built a weapon designed to combat the phoenix force!!!
This is the galactus protocol having super paranoid/prepared competent Black Panther we know and love.
Tchalla's leadership is on full display and the side characters in the story are allowed space to be themselves at no ones detriment. Okoye was aggressive and bullheaded at times but listened to. The three together are quite a force.
Re-reading now but i really need more of these characterizations and more of the vault room's secrects.
