Listing some major CHIKARA stuff below;
I don't know if the CHIKARA roster should be huge for this update with The Flood storyline, but I do notice some workers not present that were on the return show and advertised for future shows that aren't listed on the roster like
Ashley Remmington
Sinn Bohdi
Qefka the Quiet
Oliver Grimsley
Dr. Cube
JAKA
Oleg
Sidney Bakabella
Devistation Corporation
The Baltic Seige
etc. etc.
Also, I do believe Vin Gerard works as some sort of a staff member for CHIKARA as hinted by Leonard F. Chikarason outside the building at "You Only Live Twice".
The Wrecking Crew should be a stable in CHIKARA with Sidney Bakabella, Oleg The Usurper, JAKA, Max Smashmaster, Flex Rumblecrunch, and Blaster McMassive. The Odditorium should be a stable with Sinn Bohdi, Oliver Gimsley and Qefka the Quiet.
deviAnt should actually be in the Colony: Xtreme Force stable instead of Gekido.
Kayfabe wise, Robbie Ellis is the new CHIKARA owner and did appear with Shayne Hawke. I don't know if that would qualify both as being added the roster of sort.
