Kai and Nya are Smith, Jay is Walker, and Zane is Julien. You think the wikia for LEGO Dimensions is more accurate than the wiki specifically made for Ninjago?

Kai, Nya, Zane, and Cole don't have official canon names. The last names used in the blooper reel are non-canon. We don't know if Julien is even Dr. Julien's last name. Until they are mentioned in the show, and/or official material made for the show, their last names are blank.

And I mean, "for the show". If Cole turns out to be "Cole Brickman" in the movie, it still isn't his last name in the show.

As of now, the only ninja with full names are Lloyd Montgomery Garmadon and Jay Walker (born: Jay Gordon).
