got your back bro. After Black panther's fight with Iron Fist, he realised that he had brain damage and left Wakanda for a while just to get away from it all. An NYPD officer that was friends with an old pal of T'challa's found the suit and used it (along with his stupidly good marksmanship) to take out the gangs around the city. Bla, bla, bla, panther gave him a new suit when he found out about him, bla, bla, bla, gave him the heart shaped herb, bla, bla, now he's the white tiger.
might have to change my name to heartslash now. That sounds even more likely to be made by Liefeld than Deathslash.
No. He's black and his real name isn't Kasper. He's just called that because his skin color is closer to a white persons than it is to a black persons.
