[Mass Effect + Other(s)] How would other science fiction universes fair against the Reapers?
gpt
Doc Brown, eager to see the far future, travels to 2185, only to find Earth under attack by the reapers. He tricks a group of Batarian terrorists into giving him a case of element zero before returning to 1985.

Once he's back, he retrofits the Delorean with a hyperdrive, and recruits Marty, telling him that something's gotta be done about his great-great-great-great-great-great-grand kids! They go back to the distant future, only to find Ziff Tannen planning to sell out the survivors of Hill Valley to the reapers.

After they defeat him, they develop a desperate plan to stop the reapers. Doc sneaks onto the Crucible, pretending to be a scientist performing experiments to study the solar wind. In reality, he retrofits the Crucible to be a gigantic speaker.

As the reapers close in, Marty hooks his guitar to the Crucible, plays Johnny B. Goode at a volume sufficient to rock several galaxies, and defeats the Reapers with the power of rock and roll.
