The princess then focused her efforts on proving her worth by completing a series of challenges. She walked barefoot across fire, meditated for hours in a scorpion pit, and even free-climbed the mountain that was home to the heart-shaped herbs... Herbs that happened to be surrounded by a pride of panthers.
Having acquired the herb, she ingested it back in the palace and met with Bast, the Panther God. The meeting did not go as planned, though, when Shuri's arrogance led her to declare her worthiness instead of presenting herself humbly. The god told her to go, saying that she would never be the Black Panther. After conveying this to the others, Zuri pointed out that the god must have seen something in her because it usually destroyed anyone deemed unworthy.
With Morlun attacking Wakanda, the country needed a hero while Storm attempted to save T'Challa from Death in Limbo. Shuri answered the call and donned the Black Panther costume for the first time, understanding that she needed to prove herself by overcoming her arrogance and ego. While she defeated Morlun, T'Challa returned to consciousness, but did not retake the Black Panther title, leaving it to Shuri for a time.
In the second half of that BLACK PANTHER volume, Shuri traveled to America, where she was attacked. Shuri and her crew investigated the encounter which uncovered a revolutionary group of Wakandans called the Desturi that had been manipulated by Doctor Doom. The Latverian leader orchestrated a fight between her and Namor. However, the truth came to light when the Fantastic Four showed up.
