He is the only survivor of Majin Buu's first attack under Bibidi's control. He took the place of Supreme Kai and was the ruling Kai until Elder Kai showed up. He is thought to be the most powerful being but doesn't come close to most of the Z fighter's levels. He ends up fusing with Kibito with the Potara Earrings.
Shin has very few fighting scenes, and as a result his exact power is not clearly demonstrated. During his brief fight against Buu his attacks were able to stagger the monster but not able to cause any real damage apart from a full power blast being able to blow a hole clean through Buu although this barely phased Buu as he got right back up as if nothing happened. It is clear, however, that he is much more powerful than Frieza (before his temporary resurrection), due to his statement of all the Supreme Kais being able to defeat Frieza in one blow, yet not able to kill Buu. It is also known that he is more powerful than his servant Kibito. In the original Japanese manga, Piccolo states that his and Shin's powers are dimensions apart. His original Japanese line is "Chigai-sugiru... jigen ga..." ("Our dimensions... are too different"; this is the same thing Tien Shinhan says about Super Saiyan Goku in the Androids Saga). However, Shin shows signs of weakness, as he is amazed at the powers of Goku, Vegeta, and Gohan. He is also scared of Dabura's power, as well as even Yakon, even prior to them becoming Babidi's servants.
In Dragon Ball Super, Goku mentions after fighting Zamasu for the first time that Zamasu is far stronger then Shin.
In the English version of the anime, Shin says that the Supreme Kais were a thousand times stronger than Frieza, and also states that his power is lower than that of any of the other four Supreme Kais (however it should be noted that he was referring to Frieza's power in the time period before Frieza's temporary resurrection and training).
- Statements by authors and guidebooks
The Daizenshuu 7 guidebook goes further and states that Shin possesses strength "far superior to the Super Namekian Piccolo".

- Life Link - According to Whis, Shin's and Beerus' lives are linked to one another, so if one of them dies, the other will die as well (in a manner similar to Piccolo and Kami) in order to prevent an imbalance between the natural forces of creation and destruction which Shin and Beerus represent.
