This episode is loosely based on "The X-Men" (Vol. 1) #1 where the X-Men face Magneto for the first time.
The control officer at the military base that Magneto attacks looks exactly like the officer Morph impersonated in Night Of The Sentinels Part II (1992) but the voice is different. This could be because Morph only has seen the officer before but never heard him speak.
Gambit and Rogue do not appear in this episode.
Beast reads a book by George Orwell, who came up with an Orwellian society describing a situation, idea, or societal condition identified as being destructive to the welfare of a free and open society similar to the Days of Future Past alternate future.
Beast turns the page from right to left, meaning that he is reading it backwards.
