Sailormoon S and Naruto - in which demon priestess Mistress 9 succeeds in summon her Pharaoh 9T early, only to discover that there's been some changes in the situation due to the decade she was gone and a time differential between the two worlds of over 8:1... My suggestion for when to pull Naruto out of his own series is after the first success with taking all the Kyuubi's power on the giant turtle training area, but before he fully mastered it, so the time in SM-land fills out the days he would have spent being mushroomed while the 4th Great Shinobi War built up, and instead of slipping past his minders to run off alone he appears (himself having gained at least some and possibly a lot of extra battle experience in the interim, and probably adapted at least some amount of magic use to ninjutsu style attacks) with a full roster of moderately-to-extremely powerful Senshi depending on when they come back from in that timeline, who want to help their friend bring peace to his world like he helped them with theirs.
