Unlike Link & Ganon or Mario & Bowser, Ridley and Samus have one very clear storyline.
And they hate each other.
A playful and friendly child, Samus Aran lived with her parents on a colony until it was attacked by Space Pirates led by Ridley. The Chozo, a race of bird-like aliens, arrived too late to stop the colony’s massacre, and took in Samus, the only survivor.
Takeaway: Ridley killed Samus’ parents and destroyed her home.
Samus’ upbringing was placed in the hands (talons?) of two of the Chozo, Old Bird and Gray Voice. To make sure that Samus could survive on the Chozo homeworld of Zebes, Gray Voice spliced some of his genes into Samus’ DNA, making her part-Chozo.
When Samus was only a teenager, the Chozo were betrayed by their supercomputer, Mother Brain. Mother Brain summoned Ridley’s Space Pirates to Zebes, lowering the planet’s defenses in return for the Space Pirates’ allegiance.
Samus was only able to escape the Space Pirate siege because Gray Voice sacrificed himself to get her off Zebes.
Takeaway: Ridley killed Samus’ adopted parent, and destroyed her home AGAIN.
Years later, Samus returned to Zebes as a seasoned warrior. Ridley and Mother Brain were trying to harness the power of Metroids – strange creatures created by the Chozo to be an ultimate weapon against the deadliest creatures in the galaxy. Samus triumphed.
Takeaway: Samus blew up the Space Pirate base, blew up the Ridley’s flagship, blew up Mother Brain, blew up Ridley, and blew up a robot copy Ridley had made of himself.
What was left of Ridley was recovered by surviving space pirates, who turned him into a cybernetic monstrosity. Although Ridley never speaks in games, logs written by Space Pirates indicated that he was brilliant, cunning, and cruel, with a sadistic sense of humor. He fought Samus several times while trying to obtain a powerful substance called Phazon, and eventually fought her with a Phazon-enhanced body. Samus triumphed.
Takeaway: Samus blew up Ridley again and again, regardless of what he did to enhance his body.
When trying to eliminate the threat of Metroids once and for all by wiping out a planet infested with them, Samus came across a newly-hatched “baby” Metroid that imprinted upon her as if she was its mother. Feeling compassion, she spared it… and then Ridley tried to kidnap it, but was stopped by Samus.
And then, as soon as she let down her guard, Ridley returned and kidnapped the baby Metroid. He took it back to Zebes, where Mother Brain had been repaired. Samus was able to defeat them again, but the baby Metroid was killed in the battle, sacrificing itself to save Samus. Samus destroyed Zebes.
Takeaway: Ridley kidnapped a baby Metroid that saw Samus as its mother, leading to its death. Samus blew up Ridley again, and then blew up the entire planet he was on.
(Summary: Ridley killed Samus family, then destroyed her adopted family, laid waste to every home she’s ever known, and kidnapped an alien child that viewed Samus as it’s mother, causing it’s death. Samus has blown him up countless times, even blowing up an entire planet with him on it.)
Ridley finally showed up in Smash.
Takeaway:
this is literally just a callout post
Don’t forget it’s canon that she developed PTSD from her first encounter with Ridley, and it’s only specifically tied to Ridley (no other Space Pirate has caused her to have a panic attack). She has a severe panic attack when she meets him for the second time, and is only able to push through it with the help of the Chozos comforting and protecting her.
It happens in volume 2 of the manga (that was only released in Japan) right here,starting from chapter 8, if you want to see it.
If y’all count Other M as part of the canon, she has a slight relapse when Clone Ridley attacks (likely having dropped her guard thinking Ridley was dead for good after their battle in Super Metroid).
Takeaway: The traumatic event that took place during Samus’ childhood–Ridley attacking and killing her colony, even killing and eating her parents in front of her–gave her PTSD, and at least twice in-canon events she suffers from a panic attack when she’s face-to-face with Ridley, and ONLY RIDLEY causes this.
