Zaraki is back, but even his fighting spirit won’t be enough to overcome Jiren. Jiren is effectively unbeatable. His power is completely unwavering and his energy attacks are almost infinitely strong. Zaraki would get obliterated the instant that the fight starts. That’s how big the power gap is here. Zaraki had a good run though and he did make it pretty far. Maybe he would be able to cut through and land a hit on Jiren, but I wouldn’t count on it. Jiren wins.
