While "2000 AD" writers and editors have generally ensured that events occurring in spin-offs and their parent series are usually mutually consistent with each other, so that events in one such strip do not contradict events in another, much less care – if any – is taken to ensure a uniform continuity between crossover series. Therefore, while events which occur in the "Anderson, Psi Division" spin-off may have repercussions in "Judge Dredd" and "vice versa", the continuity of "Strontium Dog" might be ignored.
