Black Panther Civil War
After rewatching the film I have some suggestions that keep in character with the film but also improve the MCOC version.
1) Panther receives a fury and/or regeneration if knocked down, recall after Bucky knocks T’Challa backwards in the cafeteria he up again with renewed vigor.
2) Panther gains power if defender holds block too long. Justification is from when Bucky and Panther were at a standstill on the steps and Panther performed a special move almost out of nowhere.
3) Projectiles attacks that do physical damage do none or vastly reduced. Why? Because the 50 caliber fire from the helicopter on Panther did nothing.
Lastly Panther’s heavy attack are unblockable. This is nearly self evident as Panther heavy claw attack slice through everything except Captain America’s shield.
