there's more to him than meets the eye.

[Toygirl2]

Hi guys:

The following is from a scene of Seinfeld where Seinfeld found out his gf used to go out with Newman:-

Jerry: No. It isn't and the most distressing part of it is, not that she went out with him but that HE stopped seeing her. Do you understand? He, Newman; Newman stopped seeing her. Newman never stopped seeing anybody. Newman will see whoever is willing to see him. Not so much why she did see him as disturbing as that is. But why, did HE, Newman, stop seeing her?
Elaine: Perhaps there's more to him than meets the eye.
Jerry: No, there's less.
Elaine: It's possible.
Jerry: No it isn't. I've looked into his eyes. He's pure evil.
Elaine: He's an enigma, a mystery wrapped in a riddle.

What does the sentence "there's more to him than meets the eye" mean in that conversation?

please advise

He's better (has more good qualities about him) than it may appear at first glance.
