Yes, in Jain tradition, Manibhadraveer (also known as Manibhadra Yaksha) is considered a Yaksha, a type of divine protector or attendant deity. According to Jain beliefs, Manibhadraveer is closely associated with Adeshwar Bhagwan, who is also known as Rishabhdev or the first Tirthankara.

In many Jain temples, especially those dedicated to Adeshwar Bhagwan (Rishabhdev), you will find shrines or images of Manibhadraveer. Devotees believe that Manibhadraveer serves as a guardian deity (Shasanadev or Yaksha) who protects the devotees and the temple, and he is often worshipped for blessings and protection. The connection is especially prominent in the Shvetambara Jain tradition, where Manibhadraveer is venerated as a powerful Yaksha associated with Adeshwar Bhagwan.

So, Manibhadraveer is indeed connected to Adeshwar Bhagwan as his Yaksha or attendant deity in Jain tradition.
