Black Panther scans courtesy of Dermie!
According to Dermie:
Here are some scans from BLACK PANTHER #12. T'Challa (and agent Ross) have been captured by his enemy Achebe, and locked in a giant death trap. Achebe also took T'Challa's costume so he could impersonate the Black Panther, so T'Challa is naked...much to Ross' discomfort.
