- Earth 12 is based on the earlier concepts of Earth-12 and the DCAU; it is virtually identical to the latter (at least regarding Batman Beyond material anyway).
- The DC Entertainment Essential Graphic Novels and Chronology 2015 confirms that the title Batman Beyond Universe takes place on this Earth; as it was published after the events of Flashpoint, its prequel series Batman Beyond Unlimited can also be deemed canonical. It is unclear if and how previous stories such as Hush Beyond or the larger DC Animated Universe fit in Earth 12.
- Earth 12 is opposite Earth 50 in the structure of the Multiverse.
- Earth 12 is part of the area in the local Multiverse termed "The Cartoon Rim" with Earths 21, 26, 42, and sometimes 16.
