So, long story short, my pops moved out of my old house (well, it's getting foreclosed... another story) and I got the call from my Mom that he's left town and a bunch of my old stuff was found in the garage, a bunch of old toys and stuff. For reference, the garage was disgusting, tons of rat and bug droppings, a bunch of real unpleasant stuff. My gf is getting real into the Transformers lately, and right around the RiD / Armada / Energon lines I was collecting quite a bit so we decided to go into the garage and see what we could find (at her request).
I think we did pretty well, all things considered.. most of the stuff was sealed in boxes (the figs were loose in cardboard boxes from when we moved the first time), the only hassle was getting all the appropriate weapons for them. Here's a full list of what I found... to be honest, I forgot I even owned most of this stuff, except the G1 reissues which I knew where I put them.
Everything here we ended up making complete, unless noted:
G1 original:
Six Shot (Missing two guns)
G1 Reissues - Still sealed in mint boxes
Optimus Prime
Hot Rod
Starscream
Heroes of Cybertron figs:
Optimus Prime
Powermaster OP
Starscream (Missing a laser

)
Skywarp
Robots in Disguise:
Scourge
Ruination (all 5 were already combined)
Prowl
Ultra Magnus + Optimus Prime (Magnus is complete I think, Optimus is missing a gun I might be able to go back and find)
Storm Jet (one open, one sealed... for some reason?)
Obsidian
Sideways / Axer
Super Side Burn
Alternators:
Smokescreen (still sealed in the box)
Armada:
Unicron
Sideways
Optimus Prime
Cyclonus
Starscream (the big deluxe version)
Energon:
Battle Ravage (He's missing some glowy yellow thing that goes to his chest)
Starscream
Scorpnok (still sealed, box is all beat up... gonna open him)
Rodimus
I think that is all of them.. I think I may still have Hot Shot from Armada and X-Brawn from RiD in there, somewhere... but as we were looking, a shelf ended up collapsing and it got too disgusting to keep looking. I am glad I saved who I did! Even if a few of them are incomplete, they look awesome on the shelf next to the Classics line Grimlock and all the Mighty Muggs TF's.
I also ended up finding my old VHS copy of TF: The Movie, and about 50 or so old school Marvel TF comics... all in all, it was a fun day. We left a TON of G.I Joes there and are debating going back for those, a lot of ones from the early 2000 reissues. The problem is they are all loose, I'm unsure of the condition, and putting figures with correct weapons is going to be nigh impossible... I might just mix and match.
