Well, ya'll said you didn't mind long lists...
1. Has anyone else noticed that in fics where it's the Autobots that are the bad guys, they seem to be so much more evil than canon Decepticons?
2. What if Omega Supreme suspected something was wrong the moment the Constructicons tried to lure him away from Crystal City?
3. What if Autobots, not Decepticons, had robot mode flight?
4. Art. Bunny Constructicons. Because while kitty transformers are adorable, I've never seen bunny ones.
5. ?: "Maybe we'll find some place to... hook it in."
Hook: "... Stop trying to be funny."
6. "Why do we keep getting turned into humans?"
"I'm wondering how."
7. "I was trying to build his funeral down there."
8. Perceptor is a lot younger than most people think. Only Wheeljack and Ratchet know his true age.
9. "If nobody asks, don't answer."
10. Perceptor's creators were criminals who lived on the run, taking Perceptor with them until he was old enough to survive on his own.
11. What was life like for the Constructicons before they met each other?
12. Magnetic Jewelry.
13. For the record, he thinks Hook is a lot more hurt than he sounds... but he has to keep up the appearance of not caring.
14. What if the Autobots and Decepticons awakened during the American Civil War?
15. Live his life forever to the best of his ability.
16. So much to remember, yet forgotten to ask.
17. A publisher overhears some of Kup's stories and tries to get him to write a book.
18. Perceptor, when the Ark crashed, did not go into stasis, his injuries causing that system to malfunction. He also suffered other injuries, including injuries to his CPU. Because of this, he was unable to wake any of the others and spent the next several million years completely alone.
19. After merging as Devastator, when they separate, the Constructicons have trouble remembering who is who.
20. Perceptor wasn't used to Shockwave knowing his name.
21. He hated the sky.
22. Perceptor spent a brief time, before the war, as a patient in a mental hospital.
23. It took skill to recognize when Hook was in a good mood.
24. If a sparkling had been on the Ark, how would the millions of years spent in stasis have affected him?
25. The city Perceptor is originally from is 'outside of time' and only appears once every hundred vorn. And this city is considered a myth.
26. "I don't understand. We used to be so close. Why is he so afraid of me now?"
27. "He'll fight you, you know. They've tormented him so much he's unable to comprehend the possibility that not everyone wants to hurt him."
28. "I've often wondered why his creators named him Perceptor, when he seems to always be wandering through life in an oblivious haze..."
29. Megatron makes the mistake of trying to separate the Constructicons.
30. The Dinobots often bring things they've found to Perceptor so he can tell them what it is.
31. Perceptor's thought processes are so... complex, so unique... that he has great difficulty interacting with the outside world.
32. While merged as Devastator, Hook is severely injured. The injury will prove fatal if he doesn't receive medical attention immediately. The Constructicons separate, though only physically; they stay connected mentally in an attempt to keep Hook's mind alive, even if his body is dying.
33. No one ever seems to realize that, as observant as he is, Perceptor would make an excellent tracker. Or that, if he felt like it, he could conceal his own trail well enough that not even the most skilled trackers currently on Earth could follow him.
34. Hook's dying and he tries so hard to keep this a secret from the other Constructicons.
35. Grimlock and Perceptor have a conversation. And shockingly, Grimlock is using proper grammar and actually sounds intelligent. Then another Autobot comes their way and, after Perceptor warns Grimlock that they're about to have company, the Dinobot goes back to his usual manner of speech. Seems the Dinobots, or at least Grimlock, are a lot smarter than they let on. Why hide this? And why was Perceptor let in on the secret?
36. A group of humans studies the Decepticons (from a safe distance) and notice some similarities between the Decepticons and several cults.
37. Starscream found it kind of creepy how the Constructicons occasionally did their 'we are of one mind' thing. Note: By 'we are of one mind' I do not mean combined as Devastator.
38. They wondered what about this situation made Hook so nervous. They'd tried asking, but Hook himself didn't seem to know.
39. Hook calls it torture; Scrapper calls it therapy. Hook: "Let me up so I can go fix it!"
Scrapper: "No. You are going to sit here and let it remain as it is."
Hook: "But it's... flawed."
Scrapper: "It works fine. It may not be perfect but it is good enough. Now sit still."
40. ?: *sees still smoking ruins* "Ok... Perceptor and Wheeljack aren't allowed to play together anymore."
41. Sparkling!Wheeljack's first explosion.
42. There are several mechs that Optimus needs to be extra gentle in dealing with...
43. When Hook seems to stop caring about his work, leaving projects unfinished, the others know something is wrong.
45. During a time when supplies are limited, Megatron decides to place some Decepticons in stasis, including most of the Constructicons. Since Hook's the medic, he's the only Constructicon not ordered into stasis. But since they're Gestalt, they have a way of getting around being in stasis. All they do is take up residence in Hook's mind.
46. If the Constructicons do not merge, the reprogramming becomes unstable.
47. Hook is blinded in an attack.
48. Someone (#1) is in love with Someone (#2) who is already in a relationship. So #1 spreads a rumor that #2's lover is abusive. So #2 is separated from his lover (because no one believes him when he says he hasn't been abused), and #1 comes along to 'comfort' him.
49. He'd been around the block so many times the blocks had been compressed into tiny little squares.
50. Very rarely would a few monsters be able to hurt them.
51. Art. Dead End holding a sparkling Hook.
52. "That Crystal City kitten."
53. Crossover with Star Trek. Spock and Perceptor discuss science.
54. Art. Grapple and Hoist with a sparkling Hook.
55. Crossover with Star Trek: Voyager. Voyager encounters the Junkions.
56. Wreck-gar/Perceptor.
57. How would the Junkions react to being turned human?
58. "Perceptor with his Geek speak. Beachcomber with his Hippie speak. Wreck-gar with his TV speak... Does anyone here speak Cybertronian? Or English, even?"
59. In the Afterlife, time has no meaning. You can be reborn whenever you like, whether it be the distant future or far distant past. You can even be reborn as another species, worlds away.
60. "Perceptor's harmless right?" Of course he is.
61. Hook is haunted by memories of what once was, and what can never be again.
62. Hook has worked himself to near collapse... again. The other Constructicons are getting tired of this self destructive behavior.
63. How does Devastator feel when he's split apart?
64. Perceptor fakes his death and leaves. But he's not exactly running away from the war; there's just something he needs to do and he can't afford having anything to hold him back.
65. Xover with The Sentinel. Humans. Perceptor has Sentinel enhanced vision. Hook has a Sentinel enhanced sense of touch. Anyone else is up to you.
66. Even Cybertron has it's royalty. Perceptor is a Prince, though he tries very hard to keep this a secret.
67. "I wish I could see like Perceptor sees."
68. "You need to take better care of your Seer, Autobot."
69. Talk about the potential LOL of a Breakdown experience.

75. He wasn't one to just roll over and take it/die/give up.

77. "What do you care?"
"I care when Hook starts ripping out his own parts to save you."
78. He almost felt guilty for hurting the Constructicon.
79. "How did I become your family doctor?"
80. Someone forcibly ripped the information from his mind.
