WARNING: Mild spoilers for The 100 ahead. Read at your own risk.

Considering its passionate fanbase, it's no shock that The 100 had a big presence at San Diego Comic-Con 2016. The post-apocalyptic drama premiered an explosive sizzle reel for its upcoming Season 4 following a controversial Season 3, and if you're a fan you'll definitely want to check it out.

Showrunner Jason Rothenberg told SDCC audiences that the big bad of Season 4 isn't necessarily a person, but instead the very thing that the 100 have fought to survive on since the show's beginning — Earth. At the end of Season 3, series hero Clarke was left with the foreboding knowledge that Earth is time-bomb, and has only months before it succumbs to nuclear radiation. And as Rothenberg teased, "The earth will strike back." If the sizzle reel makes anything clear, it's that the 100 are going to have a tough road ahead if they want to stay on the planet.

Breaking Down The Sizzle Reel

The Season 4 sizzle reel walked fans through the past three seasons of The 100, giving us a hard look at the jagged path the world's last remaining humans have travelled. Clarke narrates as we watch the group grow from frightened children to seasoned warriors. As she says:

"In the beginning there was no hope, we were just another generation born to die in space. Then they sent us to the ground. "
The 100 arrive on Earth.

We saw the dead come back to life as Finn, Lexa, and Lincoln appeared once more to remind us why the 100 continue to fight. Death is a familiar theme on the show, but it's often what drives the characters to push through their challenges. Clarke's narration reminds us of that fact:

"Suddenly, we had hope, and we discovered that hope is something worth fighting for."
Clarke and Lexa reunited.

The 100 have had to do their fair share of killing in order to survive on their new home planet. We've seen Clarke, Bellamy, Monty, and Octavia lose a part of themselves by taking another's life in an order to keep the Skaikru safe. Watching Monty kill his own mother, we saw that for some, the cost is more than for others.

After seeing multiple instances of death and sacrifice, Clarke introduces us to the greatest threat the 100 will ever face — Earth itself. When she learned the planet was months away from becoming a nuclear wasteland, she decided to fight against it and subject her people to Earth's nuclear wrath, despite the looming threat of imminent death. As we hear in the sizzle reel:

"But now, enemy isn't something that can be fought, it can't be reasoned with, it can't be killed."

In one final never before seen apocalyptic shot, we see Polis being destroyed in a nuclear storm, killing all its wake. How can the 100 possibly survive this? Can they find the remaining four percent of the earth left habitable? Will it be enough?

At The 100's SDCC panel, Rothenberg commented that in Season 4 Clarke will fight to keep everyone alive, while others will resent her, deciding to live the best life they can with what time they have left. Destruction is inevitable, but the 100 can still survive the chaos. As the villainous A.L.I.E. revealed last season, four percent of the planet will remain unaffected and habitable. We can expect Bellamy to be on Clarke's side as she attempts to find a home for humanity's last survivors. With the two finally reunited, Season 4 will likely keep them together, despite Rothenberg's comments that characters will be separated.

Another surprise announcement was that Zach McGowan, who plays the grounder Roan, has joined The 100 as series regular. This could suggest a new alliance between the Grounders and Skaikru as they face this threat together.

Season 4 has set itself up to be the strongest season of the series yet, with all the characters primed to start fresh journeys following a three year war. Could the threat of Earth push Skaikru back to space? Or will they find somewhere new they can survive and thrive?

The 100 Season 4 premieres on The CW in 2017. Are you excited for the show's return? Let me know in the comments below.
