Avengers: Age of Ultron saw our favourite Marvel Cinematic Universe heroes going up against the powerful robotic villain.

Of course, as you would expect, the heroes prevailed – defeating Ultron, with Vision landing the decisive final blow and ending the threat of the titular villain.

Or did they?

Nothing is ever certain in the world of comic book superheroes and supervillains – you only have to look at the “deaths” of the likes of Phil Coulson, Loki and Nick Fury in previous movies to know that – and Ultron could well return at some point.

This article will look into some potential ways that could happen. Here are seven ways Ultron could re-emerge in the Marvel Cinematic Universe.

Vision Being Corrupted

Ultron came to be when code from the Mind Gem was input into Tony Stark and Bruce Banner’s previous programming code – programming code which had been written in an attempt to make a sentient A.I.

When he awakened, he encountered J.A.R.V.I.S., whom he attacked, before building himself a crude body, attacking the Avengers and heading out into the world.

He built himself a body – the Vision – but the body was brought to life as a hero by Thor’s lightning, with J.A.R.V.I.S. acting as its A.I.

With that in mind, Vision is essentially made up of three things that Ultron has encountered – the synthetic body, the Mind Gem and J.A.R.V.I.S.

There could still be traces of him inside Vision and, as such, he could eventually override Vision’s current consciousness and re-emerge in Vision’s body (or somebody else could make that happen).
