Transformers: Rise Of The Beasts Ending And Mid-Credits Scene Explained

gamespot.com:

With Transformers: Rise of the Beasts, the live-action Transformers franchise certainly isn't getting less complicated. It introduces two brand-new-to-live-action factions of space robots--the Maximals and the Terrorcons--while also doing more stuff with Unicron and setting up some other things I can't talk about until after I've given you a spoiler warning.

So without further ado…

Warning: This article contains major spoilers for Transformers: Rise of the Beasts, including all the details of the ending.

Rise of the Beasts picks up the story in 1994, seven years after the events of Bumblebee. Optimus Prime and the other Autobots are still hiding on Earth, refugees from the war on Cybertron. And a completely unrelated conflict is brewing: Unicron, the planet-sized world-eater, needs the franchise's latest Macguffin, a Transformer relic called the transwarp key, so it can resume its world-eating journey across the universe. And, of course, the key is on Earth. Why would a Transformer relic be anywhere else?

The key is on Earth because one of those new Transformer factions, the Maximals, brought it here a long time ago to safeguard it from Unicron's forces. But those forces, led by the Terrorcon called Scourge, are now on Earth too, and they've caught the scent. And we know they mean business, because they manage to kill Bumblebee during their first fight against the Autobots. You read that right: Bumblebee died.

There's a lot of back-and-forth throughout the film, but eventually Scourge does get the key and starts the process of bringing Unicron to Earth. And it's up to the Autobots, Maximals and their new human pals Noah and Elena to somehow prevent that from happening--because if Unicron gets to Earth, everybody dies.
