spoilers!
My version of IDW's Glitch was made from a WFC Cliffjumper and a movie Camshaft head and hands. I had to make new balljoints for the hands to plug in, and the left one broke after I put it in. I superglued the hand in place, so I don't think I'll be transforming it again.
I do have plans to make Tarn but it depends on an online retailer filling a months old order.....
Edit: I've joined big bad Photobucket, so hopefully the images will show. It's a learning curve.
