Adam Cole was recently interviewed on a YouTube series and asked to compare being in the Undisputed Era in NXT to his time in the Bullet Club before that:
"I've been in a lot of different factions my whole career and all the guys who made up those factions are different performers. For example, if you look at the Undisputed Era as a whole I'm very different than Roderick Strong who's very different from Kyle O'Reilly who's very different from Bobby Fish. Bullet Club was the exact same way. Everyone was different but together collectively that's what made The Bullet Club what it was.
Of course you're gonna see people who compare the groups especially when someone jumps from group to group. Undisputed Era has the same cocky, no-nonsense, do whatever we want attitude that Bullet Club does so you get the comparisons, but at the same time I do think the group that we have now in the Undisputed Era is different in that sense. I definitely have noticed differences, yeah."
