Ninjago was created by Tommy Andreasen and Michael Hegner for The Lego Group, as the core concept and the original TV series grew out of their work developing a new ninja-themed Lego property around 2009–2011.

Quick Scoop

  • The Lego Ninjago toy theme and story concept started from a rough sketch by concept developer Tommy Andreasen showing elemental ninjas and the word “Spinjago,” which evolved into “Spinjitzu.”
  • The animated series Ninjago: Masters of Spinjitzu (later just Ninjago) is credited as being created by Michael Hegner and Tommy Andreasen, who helped define the world, tone, and core ninja team.
  • Over time, writers Dan and Kevin Hageman and other creatives expanded the lore, adding major story arcs and characters like Lloyd Garmadon, but the original creation credit stays with Andreasen and Hegner.

In short: Ninjago as fans know it today is the result of Lego’s internal concept team, led creatively by Tommy Andreasen (with Michael Hegner on the TV side), turning a ninja sketch into a full-blown universe.
