NEWARK — It’s hard to overstate how imperious T.O.P. looks onstage. The oldest member of the outlandishly popular K-pop boy band BigBang, he walks slowly, almost reluctantly. He regards his surroundings with Clooney-like reserve. If it’s possible to be rolling your eyes while maintaining fierce eye contact with several thousand people, he can do that. He stands ramrod straight, making it seem as if he’s always peering down on what’s transpiring around him.

What’s happening is an extreme, intense, overwhelming Korean pop carnival, and at the Prudential Center on Sunday night — the second of two shows here — T.O.P. was almost certainly the only one over it all. For about a decade, BigBang has been one of the most innovative and popular acts in the flooded-with-talent and always-in-flux world of K-pop. Nothing has derailed the band — not the occasional scandal, romantic or legal; not long breaks, like the years that pass between albums; and not the success of G-Dragon, the group’s breakout star.

BigBang is at work on a new album, “MADE,” and has been releasing singles over the past few months that are in general less Technicolor and frenetic than its songs of a few years ago, which helped the group break out beyond Asia. (The last time BigBang played the area was three years ago, at this same venue.) This is a sign of musical evolution, and also a realization that the boy band mode comes with built-in time limits. There is also the looming specter of conscription: South Korean men are required to perform two years of military service.

But for now: G-Dragon, G-Dragon, G-Dragon — so many of the screams here were for G-Dragon, fashion show front-row habitué and collaborator with Diplo and Skrillex. Slight and baby-faced, he was toned down from his usual visual excess. As in all boy bands, there is a hierarchy here, of course: G-Dragon is very much at the top. He gets the best clothes — a fascinating patch-covered oversize bomber jacket, or a snow-white turtleneck — followed closely by T.O.P., who at one point wore what seemed to be a Mondrian print on a suit.
