Beelzebub in the Testament of Solomon

In the Testament of Solomon, Beelzebub explains he is the Lord of demons because he is one of the only heavenly angels left who had fallen. This means he was not a child of an angel but an angel himself.

“Then I summoned Beelzeboul to appear before me again. When he was seated, I thought it appropriate to ask him, ‘Why are you alone Prince of the Demons?’ He replied, ‘Because I am the only one left of the heavenly angels (who fell). I was the highest-ranking angel in heaven, the one called Beelzeboul. There is also accompanied me another ungodly (angel) whom God cut off and now, imprisoned here, he holds in his power the race of those bound by me in Tartarus. He is being nurtured in the Red Sea; when he is ready, he will come in triumph.”

“I said to him, ‘What are your activities?’ He replied, ‘I bring destruction by means of tyrants; I cause the demons to be worshiped alongside men; and I arouse desire in holy men and select priests. I bring about jealousies and murders in a country, and I instigate wars.” – TSol 6:1-4

Overall, Beelzebub is a powerful Demon. He is powerful not only because he has the ability to evoke evil but also because he is the ruler of all other demons. He is often referred to as the prince of demons. This allows him to aid King Solomon in the interrogation of other creatures.
