Item Spotlight: Infinity Stones

These are the Infinity Gems. They have a long history in Marvel Comics, beginning in Marvel Premiere #1 (February 1972), when the Soul Gem first appeared. The rest of them appeared during The Power of Warlock (1972) and were originally called Soul Gems as a group. In The Thanos Quest (1990), Thanos changes the name to Infinity Gems since only one of them controls the soul.

In the MCU, Infinity Stones (note they're not called gems) first confirmed to exist in Thor: The Dark World (2013). However, that's not the first time one appeared.

The Tesseract (aka the Cosmic Cube in the comics) was first mentioned in Iron Man 2 (2010), first appeared in the post-credits scene of Thor (2011), played a major role in Captain America: The First Avenger (2011), and then was first confirmed as an Infinity Stone in Thor: The Dark World (2013). At some point, probably in an interview, the Tesseract was confirmed to be the Space Stone.

The Aether first appeared in Thor: The Dark World (2013). At some point, it was revealed to be the Reality Stone.

The Orb first appeared in Guardians of the Galaxy (2014). It was confirmed to be the Power Stone.

The Mind Stone first appeared (sort of) as the Scepter in The Avengers (2012). The Mind Stone itself was first alluded to in Guardians of the Galaxy (2014), and then first appeared in Avengers: Age of Ultron (2015). As the gem that powers the Vision, it was combined with the Sunstone from the comics.

The Time Stone was first alluded to in Guardians of the Galaxy (2014), then first appeared as the center of the Eye of Agamotto in Doctor Strange (2016).

The Soul Stone (which is orange) has not appeared yet.

As you may have noticed, the colors of the Infinity Stones do not match the colors of the Infinity Gems. Keep that in mind below.

In the Marvel Universe, the universe was rewritten following Secret Wars. In practice, this doesn't mean much. No previous Marvel stories have been erased from existence. But it does allow them to change a few things going forward, and one of those changes is that Infinity Gems are now Infinity Stones. Other properties have changed as well.

They started reappearing in Marvel Legacy #1 (September 2017) with this blue stone.

The next one to appear was this giant purple stone in Guardians of the Galaxy #147 (November 2017). The writer says it's so big because of how much energy it has, but that it can be compressed.

Captain Marvel #126 (November 2017) debuted the next stone, a red one that was found in another reality.

The most recent one was also the first to be specifically named: the Time Stone. As you can see, it is now green. It showed up in Thanos #13 (December 2017). Interestingly, only a piece of it has been found so far, and it was found in the future.

Infinity Countdown Prime #1 (February 2018) shows that Turk Barrett has the Mind Stone...

...and Magus has the Soul Stone, until it's taken by Ultron.

Appearance Spotlight: Doctor Strange's magic

Recently, Marvel started a new initiative called Marvel Legacy that's basically supposed to get the characters back to their roots. As part of this initiative, they've started releasing brief retellings of characters' origins called Primer Pages, and Doctor Strange's is pretty interesting.

See, when Doctor Strange used his magic in comics, it generally looked like generic blasts of energy, like so:

But in the recent movie Doctor Strange (2016), they decided to make magic in the MCU look more like a mandala:

This was also how magic appeared in Guardians of the Galaxy Volume 2 (2017) when it was used by Krugarr:

And what do you know, it's also what magic looks like in the Primer Pages in Doctor Strange #381 (October 2017):

It remains to be seen whether this will become the standard appearance of magic or if it was only used in this story because it's retelling the origin and so did the movie, but surprisingly, it's not the first time magic has appeared like this in the Marvel Universe. Here's an excerpt from a miniseries called Spellbinders (2005):

If it were pretty much any other book, I'd assume Doctor Strange was purposefully referring to it. But Spellbinders was so small and inconsequential that I have a hard time believing it had any such impact. But if someone knows of an interview or something that says otherwise, let me know!
