The Pain Arc is one of the most iconic in Naruto Shippuden. We are constantly teased about this character for a good chunk of Shippuden as a mysterious, powerful figure who leads the Akatsuki. We find out through Jiraiya's spying that Pain is, in fact, a formerly deceased pupil of his. The mystery deepens when he realizes that there are, in fact, six formerly deceased people being used in a coordinated manner to lead the dangerous group known as the Akatsuki. They are the Six Paths of Pain, six separate bodies commanded by someone (Nagato) with the Rinnegan (the special eyes with many concentric circles possessed extremely rarely by some individuals in history).
This path is the Deva (Tendo in Japanese) path, capable of utilizing attractive and repulsive forces on any scale. The path uses this power to initially charge up and wipe out most of Konoha. This path used to be a student of Jiraiya from the Village Hidden in the Rain. His name was Yahiko, and he initially trained with two other students, Nagato and Konan. They were all orphans from the village and were taught by Jiraiya to survive their war-torn country. They grew up and decided to band together and end the war by founding the Akatsuki. Their goals eventually warped under the influence of another villain, and they became obsessed with harnessing power, first by acquiring the nine different Tailed Beasts in the world. This is how they come to try to capture Naruto and steal Kurama, the Nine-tails.
Pain is ultimately defeated by a new and improved Sage Mode Naruto (figure review incoming!), but the arc is pretty emotional for how quickly Pain destroys things around Naruto. The figure is also good! It comes with the Akatsuki cloth coat that works in many ways, and is a little bulky and awkward in others. The accessories are a little fewer than usual, but overall, the sculpt and paint are well done here.
