We only had 3 possible awakening users anyway (Kaido, King and Queen).
The others were too young or irrelevant overall to be an Awakened user.
And King and Queen got their special stuff, a Lunarian and a Super Cyborg. They are below Katagod, who was MC's greatest fight last arc and hyped over the roof, so they couldnt have more special things in their arsenal. MC gets the better stuff.
Here the problem is Kaido. But for what we know, he might be an Awakened user but it wasnt said explicitly.
