Marvel's Iron Fist: What Does The Ending Really Mean?
8. The Hand Live On
After making their debut in the first Daredevil season, the Hand announced themselves loudly in its follow-up, and stepped up their involvement even further in Iron Fist. They're not going anywhere either, since they've just destroyed K'Un-Lun, and Danny Rand is presumably going to be wracked with as much vengeance as he is guilt.
Presumably, Bakuto is free to return to the head of the organisation, while Madame Gao's evil splinter group will still continue to operate separately, because these shows don't really know how to replace the criminal organisation for fear of creating too much of a vacuum.
Unfortunately, the ninja group are far from as interesting as they deserve to be: mostly because they've been relegated to henchmen in a drug cartel, so it's only with mild anticipation that their continued presence can really be announced.
