The Vision is now going to be joining the very large and awesome Avengers roster. He joins Captain America, Thor, Iron Man, Hawkeye, Hulk, Widow, Quicksilver, and the Scarlet Witch.
The real question with this is… does he start out as a creation of Ultron and therefore a bad guy in the beginning until he overcomes his programming and switches sides? If so… that is going to be really similar to how Quicksilver and Scarlet Witch are rumored to join the Avengers roster. Is he instead a creation of Starks? That would make since considering the second big news…
The second big news with this is that the actor that is playing JARVIS is now the actor for Vision. So, that would imply, that JARVIS somehow becomes sentient and becomes the Vision. The previous interwebz theory is that JARVIS becomes Ultron so this… throws a wrench in that. Or does it? Could JARVIS somehow split to become good JARVIS and evil JARVIS?
For those who need a quickie intro to the Vision… he is basically an Android with human brain waves. In this case, it looks like it will be JARVIS. His powers include the usual super human stuff (strength, speed, intelligence, ect) but he also has energy projection, flight, and what is most “different” is that he can change his density. He can make himself pretty much a ghost and be completely weightless, go through walls (or people) ect. And the next second, he can be a dense and heavy as possible and almost invulverable.
Here is a good intro to Vision from the Earth’s Mightiest Heroes Cartoon.
