However, Ultraman becomes a recurring character in Ultraman Ace! He then shows up in Taro and Leo, both of which feature previous cast members from the various shows before them (Seven and Ace in particular.)

Actors from Ultraman (Akiko and Hayate) show up in Max, although not in their original characterizations. Hayate also shows up in Mebius and the Ultraman Zero film trilogy.

So while their story isn't continued per say, he does show up later on.
