This is a great idea! Aw, thank you, Sapph! *hugs*
ALL TIME FAVORITE, AND READ ALL HER OTHER TRANSFORMERS STORIES AFTER THIS ONE:
"Men Within the Machines" by Niteskye
http://www.fanfiction.net/s/3877736/1/
A completely fresh and new view upon Transfomers, with a completely new universe in a way that hasn't been explored before. I can't say more or I'll just give it away. Give the story a few chapters to get momentum, and it just keeps going. She's working on the prequel right now, with this on hiatus, but you need to read THIS story before the prequel. Trust me.

Not your typical Sam-as-Autobot story, well fleshed-out, with a wonderful tension written into it.

"Iron and Grace" by Glenn and Katina Rentholen
http://www.fanfiction.net/s/3650815/1/
This one follows Ironhide as he continues to guard Will Lennox's daughter, picking up sixteen years after the events in the 2007 movie. Long, but worth the time that it takes to read all of it. Detailed very nicely, believable characters.

"To Heal a Soul" by Water-smurf
http://www.fanfiction.net/s/3775835/1/
A young woman is out roaming in the middle of a stormy night, trying to find help, yet scared to find that help. She finds an ambulance of all things, and gets into it, not knowing that it was Ratchet. Great story, Not TOO believable after the third chapter, but a nice read.

"Allergies and Duct Tape" by Kyron
http://www.fanfiction.net/s/3816418/1/
Sam explores the base and comes upon Ratchet in a very interesting situation. And also finds out the reason why every other Autobot was avoiding the mech.

"Youngling" by Karategal
http://www.fanfiction.net/s/3694179/1/
Thus is the chronicles of Bumblebee as a Youngling. It's funny, serious, heart-wrenching, and then by the end, warms the soul. Very good story.

"Sparks and Plasma" by Lady Tecuma
http://www.fanfiction.net/s/3739984/1/
Takes place some time after other Autobots have joined Prime on earth. Chomia and Ironhide come to the conclusion that they have been given a second chance, and with that, decide upon having a Sparkling. Enter chaos, a good long story, and a plot that twists and turns pleasantly.

“Sam gazed at the metal chamber, at the bullets in his hand, and then said, ‘I guess you life-giving sentient thingies don’t believe in small favours, huh?’” Eleven chapters of non-stop action. Need I say more?

That's enough stories, don't you think? Yeah, it's all Movieverse, but dang. They're good writers. You don't see much outside of Movieverse, TF Animated and the G1 sticklers these days. And I have no idea what TFA is really about. I haven't been watching it. So! Enjoy!
