I think only once by that appellation, and even in 1 John 2:18 it names “many antichrists”. Verse 22 of that chapter expands the definition of the word too.
“Man of sin” and “son of perdition” from 2 Thessalonians 2:3; “vile person” in Daniel 11:21 and “king of fierce countenance” in Daniel 8:23.
The Lawless One
The Assyrian
The Mighty Man
The Little Horn
The Prince that shall come
The Willful King
The Man of Sin
The Vile Person
The Bloody & Deceitful Man
Among others.
