>Despite his overwhelming might, Jiren's fighting style is mostly defensive as, according to Vermoud, Jiren tends to let his opponents come to him. He will calmly allow his opponent show their hand, refusing to strike back until either required to or the opponent shows enough strength to actually compete against him, and even then, use no more strength than the amount truly needed. Once engaging in battle, his attack methods are very basic, but solid and efficient, quickly decimating the foe with sheer force. Jiren has extremely advanced movement analysis, able to near-instantly perceive and determine the flow of events.
>Once Jiren began to get serious, he unleashed such intense ki that it shook the entire Null Realm, a realm of infinite size, and stupefied everyone present. Beerus was shocked and sweating over his massive power, wondering how one person can unleash that much energy.
>Vegeta noted that Jiren (before he even began using a hint of his true power) was stronger than anyone Vegeta had ever encountered.
>After walking through all of Goku's explosions completely unfazed and uninjured and swiftly knocking him back, he proceeds to unleash a hint of his true power (Vermoud noted that Jiren hadn't used that much power in a while), firing off a regular punch with such power that the shockwaves he generated stunned Goku back into his base form.
