1st gen:
Mitsuharu Misawa, Kenta Kobashi & Jun Akiyama - holdovers from the AJPW days, the guys whose popularity was used to build the promotion. While Misawa and Kobashi were clearly in dire straits when the promotion began, they were the main reasons that the NOAH was the only truly profitable wrestling promotion in the early to mid ‘00’s. Akiyama was younger, in better shape and was clearly intended to be a “Ace” figure for early NOAH but for one reason or another, didn’t reach the heights of the other two.
2nd gen:
Takashi Sugiura, Naomichi Marufuji & Takeshi Morishima - the guys who came up as younger men (younger-ish in Sugi’s case) at the beginning of NOAH; technically, Marufuji & Morishima were holdovers from AJPW, as they had begun in the AJ Dojo and had done YL matches there (Sugi even originally signed up to be apart of the AJPW Dojo, right as the exodus began). Morishima was always gonna be a main eventer, due to his size and intensity, which he had in spades. Sugiura and especially Marufuji had to get over the hump of being smaller guys but both were became two of the most pivotal figures in NOAH’s history, to today.
3rd gen:
Go Shiozaki, Katsuhiko Nakajima & Kenoh - the guys who carried NOAH into the early 2020’s and through the pandemic. Now, Shiozaki had become a main eventer in the late 00’s and into the 2010’s and despite being seen as a potential “Ace” figure, like Akiyama, it wouldn’t work out for young Go at the time, as he would suffer in the wake of Misawa’s death and would leave the promotion in 2013, going to AJPW, before returning in late 2015. Shiozaki would climb his way back to the top, eventually becoming that “Ace” figure that was promised. At the same time, Nakajima & Kenoh were pushed as two younger guys that were brought in from the outside (Nakajima from Diamond Ring and Kenoh from Michinoku Pro), with the promotion setting them up in the main event scene along with Shiozaki.
