* MemeticMutation: ''We would have words with thee.''
* MoralEventHorizon: Ultron, already a lethal robot with homicidal desires, crosses it by killing the entire population of Slorenia.
* ToughActToFollow: Ultron's scheme in this story is of such scale that, in later stories like ComicBook/AgeOfUltron and ComicBook/UltronForever where Ultron successfully conquered the Earth, he used mostly the same technology developed in this story to do it.
