You will find ample reference in the Bible regarding this purpose, and scant reference regarding 'showing' or 'proving' anything to Satan.
But his purpose for coming into the world was to proclaim the truth, right? Wouldn't that make him the nemesis to the 'father of the lie'?
"For this I have been born, and for this I have come into the world, that I should bear witness to the truth. Everyone that is on the side of the truth listens to my voice." (John 18:37)
(Hmm! That would make him a messenger, wouldn't it?)
And consider these words at Revelation 3:14:
"And to the angel of the congregation in Laodiceia write: These are the things that the Amen says, the faithful and true witness, the beginning of the creation by God . . . "
To whom or what was Jesus faithful?
Does it have anything to do with the time Jesus was tempted? He was faithful then. Did Satan give up or just wait until a "more convenient time"? (Luke 4:13)

Not Just any angel. . .
