... since he cannot use anymore neither the moniker of the White Tiger nor the Black Panther ?

He doesn't need to have the same costume (it was only a prototype) but it would be fun to use this name again.

Also, I think that he should join the Black Musketeers, N'Gassi and Jiru .

Even if "Black Musketeers" comes from Jack Kirby himself, I think that they should have another name for the team ... So, maybe, they should be known as the Coal Tigers ?
