I consider it a point of pride that I have never used the instructions for any Transformer. Over 20 years and hundreds of Transformers later, I have not even looked at them. I haven't broken any, but sometimes those new-fangled ball-and-socket joints pop loose. I like the challenge of solving the puzzle. I have transformed enough of them now that I have a "feel" for how the conversion should take place. Omega Prime made me cry. I pulled some all nighters on the alternators. But I have never broken my streak. So...instructions or not? What TF do you think has the most difficult transformation?
