Kai Bowen

Real Name: Kai Bowen

Kai Bowen is the adolescent winner of the Wasp's "Be An Avenger For A Day" contest, whose visit coincided with an attack on the Avengers' Mansion by A.I.M. and the Wizard.   After they were captured, Kai was made an honorary Avenger and given a non-active (presumably) honorary Avengers ID card.
