For Clarification: The Sphinx version we are using is the New Warrior's Sphinx. Thus, this is why that character was put under the heading of New Warriors in the character listings. Here is the bio portion under Wikipedia.
"Later, Anath-Na Mut was resurrected by the Ka Stone, and instantly took his vengeance on the New Warriors by scattering them all through time. Meryet Karim had also re-appeared by this time, but she had realized her mistake in altering reality and no longer wanted revenge on the Warriors. When her attempt to make the Sphinx see reason failed, she gathered a small team of the Warrior's part-time members including Alex Power
, to find and bring the Warriors back to the present day, which they did. After a pitched battle between them and the Sphinx, the mysterious entity known as Sayge (aka Veritas)
came to the Warriors' aid and forced the Sphinx to face the truth about his existence. Humbled, the Sphinx admitted defeat and Meryet once again offered her love and devotion to him, which he accepted and the two merged into a composite entity and traveled back to the beginning of their shared history, but this time with the chance to live their lives correctly."
I'll see if I can find a better bio. The first version of The Sphinx battle Galactus, and is clearly not the version intended.
