* KeepCirculatingTheTapes: There are only two single-disc DVD volumes with random episodes, released only in North America and Japan. The only place you can get the entire series is on the French iTunes store, [[NoExportForYou so good luck purchasing it if you don't live in France]]. [[http://www.topix.com/forum/tv/animation/TTKM3J7LG9886L2UQ/atomic-betty-returns-to-television-worldwide-in-c- Shout! Factory was to release the series on DVD]], but sadly postponed its release, so you're stuck with reruns.
* TheOtherDarrin:
** Atomic Roger's voice actor, Dwayne Hill, took over as Minimus after Len Carlson passed away.
** Betty's grandfather was voiced by Creator/WilliamShatner in his first appearance, but in his second appearance he was voiced by Gary Krawford.
* ScrewedByTheNetwork: Started off on a primetime spot on CN. But was soon punted around the schedule before ending up on a early morning shift where barely anyone was awake to watch it.
* TalkingToHerself:
** On the rare occasion she does talk, Sarah has the same voice actor as Penelope.
** Betty and her favorite singer, Missy Miss, have the same voice.
* WhatCouldHaveBeen: ''Atomic Betty Redux'' was supposed to be a sequel set when Betty was a teenager however it became stuck in DevelopmentHell before ultimately being rejected.
