What was Jesus H. Christ's real name?

It's a secret. No one knows his name.

His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself. Revelation 19:12

Jesus

The angel of the LORD appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost. And she shall bring forth a son, and thou shalt call his name JESUS. Matthew 1:21
Thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS. Luke 1:31

Jesus Christ

Grace and truth came by Jesus Christ. John 1:17

Emmanuel

A virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel. Matthew 1:23

The Word

In the beginning was the Word, and the Word was with God, and the Word was God. John 1:1

(The Gospel of John doesn't come right out and say who "the word" is, but all Christians believe it's referring to Jesus.)

The Son of man

(Throughout the gospels, Jesus calls himself the son of man.)

And Jesus saith unto him, The foxes have holes, and the birds of the air have nests; but the Son of man hath not where to lay his head. Matthew 8:20

The Son of the Highest

He shall be great, and shall be called the Son of the Highest. Luke 1:32

The son of David

When Jesus departed thence, two blind men followed him, crying, and saying, Thou son of David, have mercy on us. Matthew 9:27

The Son of God

That holy thing which shall be born of thee shall be called the Son of God. Luke 1:35

The Holy One of God

And there was in their synagogue a man with an unclean spirit; and he cried out, Saying, ... I know thee who thou art, the Holy One of God. Mark 1:23-24

THE LORD OUR RIGHTEOUSNESS

He shall be called, THE LORD OUR RIGHTEOUSNESS. Jeremiah 23:6

Alpha and Omega

I am Alpha and Omega. Revelation 1:8

The Amen

Unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God. Revelation 3:14

The Lion of the tribe of Juda, the Root of David

Behold, the Lion of the tribe of Juda, the Root of David, hath prevailed to open the book, and to loose the seven seals thereof. Revelation 5:5

Faithful and True

I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war. Revelation 19:11

The Word of God

He was clothed with a vesture dipped in blood: and his name is called The Word of God. Revelation 19:13

King of Kings and Lord of Lords

(He shares "King of Kings" with Nebuchadnezzar. See Daniel 2:37)

He hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS. Revelation 19:16
(See: What does Jesus have written on his testicles?)

The bright and morning star

I am the root and the offspring of David, and the bright and morning star. Revelation 22:16

Since Christians (wrongly) believe that the words of Isaiah 9:6 refer to Jesus, I guess I should add the names in this verse to the list.
[Ever heard anyone (other than the Book of Mormon) call Jesus "the everlasting Father"?]

Wonderful, Counsellor, The mighty God, The everlasting Father, the Prince of Peace

For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace. Isaiah 9:6
