Failed Assassins!
Death-Dealer and Shadow Slasher.
Death-Dealer didn't deal death, and Shadow Slasher didn't even use a slashing weapon IIRC. Nodding to my QC past, I still like to use existing portraits when they make sense. So yes, that's Mirror Spock.
Korain and Tiger Claw.
Korain was a pain in the ass to paint, but worth the effort. Tiger Claw I had shared in an incomplete state before, but here he is with sharper paint and a better shade of yellow.
Sandra Chen and Black Demon Sect.
Sandra was an interesting character -- she was a skilled martial artist who ran a dojo. Her dad was under some threat by Fu Manchu, so Shang-Chi was enlisted to help. He ended up getting dosed on some heavy hallucinogenic and accidentally killing her with a single punch. Not very heroic. It would/should have been an interesting plot point to follow up on, but I'm not sure that it ever was. The Black Demon Sect were nemeses to Black Jack Tarr.
Black Demon Leader (Anna) and Black Jack Tarr.
Black Jack is the big anchor of this wave, and a good buddy of Shang-Chi. Per ComicVine.com, he appeared in 86 of the 111 issues of MOKF. He was MI-6. Anna was his ex-girlfriend, and hell hath no fury... [etc.], as is evidenced by her running the Black Demon Sect to ambush and attempt to kill BJT. These obviously use Killmonger helmets, and I'm so glad they exist so I could make these.
