A particular space pirate log entry in Prime, which gives clear orders to all soldiers suffering from phazon-related mutations to report to the authorities. Mutations beneficial to combat are rewarded with a raise and bigger food rations.
"Science Team has vapor for brains."
Metroids are not pets. Metroids are not for target practice.
Unauthorized feeding of Metroids is STILL strictly prohibited.
This is apparently a big problem for the Pirates: you can scan one Metroid in their base that is moving a bit slower than the others; the scan determines that it ate a pet treat and has indigestion.
One of the logs in Mining Station A of the Agon Wastes is about a Pirate grumbling about how all the trips to Dark Aether are draining their power. He then mentions how maybe Command will listen once the power latrines run out of energy.
A log in the Phazon Mines talks about trying to capture Samus' ship. Scientists predict that the ship has a cloaking mechanism so advanced, no one will be able to find it unless by sheer dumb luck. In reality, Samus' ship is in plain sight in an open area a couple of rooms away from some aerial pirates, although this fact could potentially be written off as the cloaking device working on everyone but Samus. Even in that case, however, it'd still be difficult to not notice the rain suddenly stopping in midair...
"Aran's Power Suit technology remains a mystery, especially the curious Morph Ball function. All attempts at duplicating it have ended in disaster: four test subjects were horribly broken and twisted when they engaged our Morph Ball prototypes. Science Team wisely decided to move on afterward."
A pair of logs side to side in a save station are rather droll for a group of ruthless pirates.
"All Holo-technicians report to Main Observatory. Maintenance required on both holomodules."
"Chief Astrogation Officer feels our current dual holoprojector system is obsolete. Please review and advise."
Omega Pirate's death. You shoot him, he slumps and collapses on top of Samus.
M. Angseth, Samus Aran fangirl.
PFC Crany: Last night at chow, Angseth starts talking about some bounty hunter and how she blew up a planet full of Space Pirates. I told her I didn't believe in fairy tales like that, and she took it personal. I just find it hard to believe that one person took out an entire Space Pirate base, that's all. But if she wants to believe in this Samus, or Bigfoot, or Santa Claus, she can.
After finally defeating the Chykka, a boss that just keeps getting back up when it seems defeated, scanning the corpse will give you a long list of information about the body's condition that basically amounts, "Yeah, it's down for good now, don't worry."
Metroid Prime: After the battle with Thardus, as Samus is turning to walk away, a small rock smacks her in the back of the head. (It conveniently makes her turn around and see a brand-new powerup!)
Go shoot a light beacon with the Annihilator Beam. Watch any Ing in the room gleefully gallop/fly to their death.
Admit it: At the bottom of the Phazon Mines in I, you got a sadistic chuckle out of unleashing a swarm of Metroids on the Space Pirates.
There is also a moment in the Phazon Mines where the player sees a missile-destructible grate on the ceiling. Naturally assuming that there is a powerup stored behind there, the player blows it up... And inadvertently kills the shadow pirate who had been hiding behind it to ambush Samus.
Also in Prime 3, Gandrayda has a chance of tripping when you fire a powerful attack at her during her boss fight.
This Troper was amused by Meta Ridley's death, in which several Chozo Statues come to life and blast him with Frickin' Laser Beams. Then he falls into the Impact Crater and...explodes! The latter is possibly justified by Meta Ridley being a cyborg.
Samus also gets a few dozen CMoAs for STILL BEATING HIM A BUNCH.
Some of the Prime 3 Pirate logs.
"After our liberation, she (Dark Samus) left us adrift. We thought this a test of our loyalty, and so we endured. Some said she abandoned us. They were promptly shot. Disciples do not doubt their leader. "
It gets better.
"As we groveled in awe, she ordered us to follow the beast through a rift in space, a wormhole. Some refused to follow, afraid of the unknown. They too were shot. Disciples must be fearless."
