By some accounts of Egyptian mythology the brother of Anubis was Horus.
Horus was one of the big gods and (supposedly) so was Anubis. Really they are both (step) brothers so they must be on the same level of power. (In a cool way...Anubis is cooler then Horus or that's my opinion)
Neither Anubis or Horus had reason to fight and find out.

In some cases, Anubis could be considered the brother of Horus as Isis was said to have raised Anubis - Anubis being the son of either Isis and Ra, of Osiris and Nephthysor of Set and Nephthys.

In the case of the Younger Horus, his mother is Isis and his father is Osiris, with a possible brother in Anubis. in the case of the Elder Horus, his sisters are Isis and Nephthys and his brothers are Osiris and Set; his wife is either Isis or Hathor. His mother is Nut and his father either Ra or Geb.
No, Horus was the son of Isis and Osiris. Anubis was his half brother, although some myths say he was his brother. Anubis's mom was Nephthys and his dad was Set.

As there is not a ancient Egyptian deity called "Horos" (Horus?) in Egyptian myth, Anubis would be it. If by "horos" you mean Horus, Anubis and Horus did not have any cause of conflict to determine who was more powerful so no one will ever know.
Horus, the God of Sky, was his half brother.
Osiris, Horus, Isis and Set all interacted with Anubis. His daughter was Kebechet and his consort was Anput.
Anubis is the son of Set and Nephthys. He is also the cousin of Horus. Anubis is the God of Mummies. Anubis is can appear as a jackal, a man with a head of a jackal, as a man or in his godly form. Hope this helps.
One would have to see the picture of Anubis with the man in order for this question to be properly answered, Anubis was frequently depicted with the dead, or Horus, or Osiris.
