Before Chen enters play or overlays: Dishonor him.
So, if I am a Unicorn player, and pay his full gold cost, what happens? Does he come into play honorable? Does he come into play dishonorable and I gain 2 honor? Or does he come into play dishonorable and I gain 0 honor?

Mod reminder: Please include Experience levels when a card has more than one. Thanks!
Assuming you mean the Experienced 2 Moto Chen...
Dishonored. The Personality's Personal Honor is now zero. Zero point Honor gain, no rehonoring.

Looked at the timing rules in more detail, and saw the above answer was incorrect.
http://rules.l5r.com/Timing:
"If two or more reactions, triggered traits, or rules procedures are triggered at the same point in time, follow this order from A through E to resolve their order.
"A. Apply any ongoing or continuous effects, such as "can not" wording, that negate or otherwise modify the occurrence that defines the trigger. "B. If the point in time is a "when" timing, continuous conditional effects that depend on the triggering occurrence take effect now. "C. Apply any triggered rulebook effects that are not part of actions, such as rehonoring Personalities instead of Honor gain." Honor gain goes here. "D. Apply any delayed effects that resolved previously and are timed to the trigger (such as, “After the next time this turn he assigns …”) The active player decides the order in which more than one of these effects apply. "E. Apply any triggered traits on cards. The active player decides the order in which more than one of these effects apply." The Experienced 2 Moto Chen's trait goes here.
Honor gain occurs, but Chen is still dishonored upon entering play.
