[SPOILER] Dies in “Crisis on Earth-X Part 1”

A menagerie of Arrowverse heroes made appearances in tonight’s “Crisis on Earth-X” crossover, but one unique one ended up meeting their end.

Spoilers for the first hour of “Crisis on Earth-X” below!

The first hour of the crossover opened on Earth-X, an alternate reality where the Nazis won World War II. A costumed avenger infiltrated their way into one of the Nazi camps, before being stopped by an evil masked archer.

The two began to fight, before the hero was unmasked, and was revealed to be the Earth-X version of James Olsen/Guardian (Mehcad Brooks). Unfortunately, Earth-X James didn’t survive for long, dying at the hands of the mysterious archer.

If you don’t keep up with Supergirl, here’s a sort of crash-course on the Arrowverse’s main version of James Olsen. James has been a facet of Supergirl since its pilot episode, serving as CatCo’s lead photographer and helping Kara Danvers/Supergirl (Melissa Benoist) with her early days as a costumed hero. The pair were even romantically linked, before Kara broke it off in the show’s Season Two premiere.

In Season Two, James decided to become a hero in his own right, taking up the mantle of Guardian. James wore a metal supersuit out in the field to hide his identity, but Kara soon discovered that his face was behind the mask. Despite Kara’s hesitancy, James continued to be Guardian, while balancing his personal life as the CEO of CatCo.

This season of Supergirl, James is now co-running CatCo with Lena Luthor (Katie McGrath), and actually has not suited up as Guardian thus far this season.

There is an interesting thread in exactly how Earth-X James became Guardian, seeing as Earth-38 James was motivated to do so because of his relationships with Kara and Clark Kent/Superman (Tyler Hoechlin). Would he have had any sort of relationship – good or bad – with Earth-X’s Kryptonians? Or was his turn into heroism impacted by something else entirely? Maybe the upcoming animated series Freedom Fighters: The Ray will provide some sort of answers.

“Crisis on Earth-X” is a four-hour event that will air on November 27th and 28th beginning at 8 p.m. and running for two hours each day; Supergirl (8 p.m. Monday), The Flash (8 p.m. Tuesday) and Legends of Tomorrow (9 p.m. Tuesday) will remain in their normal time slots but Arrow will move from Thursday to a 9 p.m. Monday placement for the week.
