Guardians Of The Galaxy Vol 2 Review: 10 Best Moments

6. Ego's Big Reveal

It wasn't exactly surprising, but it sure was effective. While on Ego's planet, Ego explains to Peter that over the millions of years he's been alive, the species he's encountered throughout the universe have been mostly disappointing, and he eventually sought to find meaning in life by propagating himself through as much of it as possible.

Ego has used his powers to plant seeds on thousands of planets that would transform them in his own image, but he needed the help of his son, Peter, to activate the seeds. Peter is just his most recent son, with Ego having previously impregnated hundreds of alien women in the hope of finding a genetically compatible son to help him activate these seeds. When they didn't fit, he killed them.

And to top it all off, Ego then explains to Peter that he planted a tumour inside his mother's head in order to kill her and ensure that he wouldn't be lured back to Earth because, after all, he did in fact love her.

This is the revelation that snaps Peter out of his hypnotic compliance, and drives the barmy third act battle against Ego.
