In the "Batman Beyond: The Call" Superman's encounter with The Preserver's menagerie would be revisited and Starro being taken to the Fortress would be a major plot point.
The mind controlling alien menace, Starro, can be seen in one of the Preserver's tanks as Superman and Lobo flee their enclosures.
Included as a bonus cartoon on the bluray release of Superman: Man of Tomorrow (2020).
In the closing credits to this episode, it states 'No Animals, Aliens or Robots were harmed during the making of this cartoon'.
