How well does Brainiac Attacks actually work when viewed as a STAS continuation? I've heard that the characterizations are wildly different but that's not a contradiction.
Works well enough for me. Here are my notes:
Brainiac was last seen during the events of "
Knight Time" where it was launched into space and seemingly destroyed. In this film, Brainiac arrives to Earth via a Meteor.
"Twilight, Pt. II" gives us our answer of why he came from space.
....and that he's a duplicate.
While it appears that Brainiac is unfamiliar with Lex Luthor, it's most likely due to being a highly damaged fragment whose memory banks were severely damaged in battle with Superman. Lex also seems to play coy with Brainiac. It's also confirmed by Perry White that Brainiac has caused trouble before, which places this film after it's introduction in "
Superman: The Animated Series".
Lex Luthor recently acquired another small piece of Kryptonite after spending "
two years and three billion dollars mining deep space", which he has kept in his possession as protection against Superman. This places the events of this film at least two years after "
Superman: The Animated Series".
Superman is working diligently to re-gain the trust of the world after the events of "
Legacy: Part II" by this time. Lex Luthor is un-characteristically in great spirits at Superman's recent failures – but makes mention that as Superman's popularity rises, his falls.
Mr. Mxyzptlk returns at the end of this film off camera. Perry White hasn't met him before and doesn't know how to pronounce his name.
When Phantom Lois mentions "
That Green Lantern guy?", she's either referring to Kyle Rayner, whom Superman has worked with before, or John Stewart, who is active by this time, but hasn't been seen on-screen yet. Most likely Kyle Rayner, since Superman has worked with him before.
Metropolis has a new mayor by this time.
The Fortress Of Solitude is destroyed in this film and Superman vows to rebuild it.
LexCorp tower appears to be a brown, extremely tall skyscraper in this film, although it's possible that it's an entirely different building.
Roses bloom on and off throughout Mid-Spring to Fall and can be seen in this film.
In "
Apokolips…Now!: Part I" the Ayers Island Nuclear Power Plant is destroyed. It seems it was replaced with a new Power Plant by this time.
