* HeyItsThatGuy: Heather, the snowboard instructor and Tommy's intended date in the three-part "There's No Business Like Snow Business", is played by Sarah Brown, who also played Caitlin Star on ''Series/VRTroopers''. Just about every kid watched those three episodes in the hope of a Rangers/Troopers crossover to no avail.
* RealLifeRelative: Tommy's brother, David Trueheart, is played by JasonDavidFrank's actual brother Eric (now deceased).
* WhatCouldHaveBeen: The Gold Ranger was originally planned to be Ryan Steele from ''Series/VRTroopers'', as Brad Hawkins provided the voice. This idea, along with Billy becoming the Gold Ranger, was scrapped in favor of the Triforian warrior Lord Trey.
* WordOfGod: Bhaumik's [[Series/PowerRangersWildForce "Forever Red"]] retroactively establishing that there was a final, unseen conflict between Rita and Zedd and the Rangers which led to a damaged Serpentera buried on the moon, and Zeo writer Jackie Marchand's [[Series/PowerRangersOperationOverdrive "Once A Ranger"]] revealing Rita was pregnant with [[EnfantTerrible Thrax]] by the events of the season finale.
** At different times, Bhaumik and Doug Sloan also went on record as saying that the ending to "A Season to Remember" is in-continuity.
