Gambit vs Black Panther
If Panther is wearing the vibranium jammies again I don't know that there's even anything Gambit can really do to him.
These are interesting questions. I'm almost positive vibranium can be overloaded. However, I don't think Gambit will have the time to actually test/try that technique since Black Panther is going to be trying to take him down. Does Black Panther get his energy daggers too? If so he may be able to tank Gambit's initial attack and then hit him from a distance.
We are the Dora Milaje. We are the daughters of the 18 tribes of Wakanda. We are the teeth of the Panther God. Out of 10,000 years of sweat and bloodshed and battle are we born. We are the women of this ancient land. Deadliest of the species. And our time has come!
