Akatsuki's Summer Vacation!
In chapter 27 of the manga, the entire Akatsuki organization went on a summer vacation because Pain believed it could bestow unbelievable power. Hidan was working at a Beach House Kakuzu built to make Akatsuki money, but spent most of the time cooling off in a way that Kakuzu found “creepy”. Hidan experimented with this by stepping half way into the sunlight causing only half his body to look creepy. Hidan later joins the rest of Akatsuki in a competition to see who can keep their sparkler lit the longest. Deidara got in a fight with Tobi during the competition causing the winner to be unclear. The Akatsuki decide to have a different kind of sparkler competition with their jutsu, destroying the beach. Kakuzu and the rest of Akatsuki noticed their skin had become darker and believed it was a sign of them becoming more powerful like Pain intended. They actually just got sunburned.
Hidan is immortal thanks to his religion and enjoys pain, allowing him to withstand very strong attacks. He is also very skilled with his weapons.
