Oh, I do hope you continue; Meggsie as an itty bitty sparkiling sounds good-that and he gets tortured. :)

Continue? Do you even have to ask? Okay, may be you do, but hell yeah, continue please! Sure it's going to be different from ROTF but for fiction's sake...

One big question: where is your Beta?
Most of these are "paper cuts", probably where fingers were trying to keep up with what the brain was sending to them. You also seem to have some problem with disappearing commas..

He’d probably have to stop at the local pawn shop to get it some cords, but he was in need of a new gaming systems ever since his Playstation2 had been stolen because of the move into town a little over a year ago. [This is a run on sentence. Please break it into at least two]

now where did you get these rhymes, cause they are great, and incredibly acurate!
lol! now thsi one, you really, REALLY have to update!

I think you should continue it anyway, sounds like you have a really good story ere.

LOL! I imagined something similar, but I had Barricade instead of Megatron in that kind of predicamet, wearing old cardboard boxes and hiding from human soldiers, because his original armor got lost during transformation XD

And why didn't they find Megatron, oh why? I could already imagin little Megs biting their fingers when they'd try to feed him XD

You really, really need to comtinue this. It's that awesome.

It suffers megatron, it suffers *evil cackle*

Poor Optimus ;_;

Whee! Megs as a sparkling! You're one of my favorite authors on this site, and you always manage to whip out the best ideas! I can't wait to read more about this - especially if Prime 'n' company find Megatron! Poor Prime, of course Megatron isn't dead! There wouldn't be two more movies if he was...

Looking forward to more! Thanks for sharing your amazing ideas and stories here!

please do continue I'm loving it already I feel so sad for Optimus losing his brother must be tough no matter how evil he was

Fantastic idea, great story plot. Only one mistake in your last paragraph when you said
'was in need of a new gaming systems'
should be either
'was in need of a new gaming system'
or
'was in need of new gaming systems'.

Just a minor gramatical error, sorry. Otherwise all-in-all everything seems to check out. It really is a great idea and I wish to see more soon! Please continue and update ass soon as you can!

Thats a very interessting Idea.
What will happen to Megatron if Ratchet block Primes spark and what will happen to Optimus?
