Transformers Prime Darkness Rising: Part 5 (2010–2013) watch online HD

Through his Space Bridge, Megatron raises the dead Transformers of Cybertron, and summons them to Earth. The Autobots have to find a way to sabotage the Bridge, or else their new home will be destroyed by the legion of undead Decepticons.

Several famous Transformers phrases are spoken in this episode:

• Ratchet says "Then by all means, let us light our darkest hour.", referencing the original Optimus Prime's famous words from The Transformers: The Movie (1986).
• Optimus Prime himself also quotes a famous sentence ("One shall stand, one shall fall."), which also originates from The Transformers: The Movie (1986), but has been used in several other Transformers media since, including Transformers (2007) and Transformers: War for Cybertron (2010).

It is revealed that some Decepticon drones transform into jets. Up to this point, the ones that appeared could only turn into cars.

Continuing the tradition set by the live action Transformers movies, Optimus Prime ends the episode with a speech, in the form of a signal he sent into space, summoning other Autobots to planet Earth.
