I was thinking about this today.... If for whatever reason I could only keep one of my Transformers... which one would it be? For myself I think I would have to go with 20th Ann. Op. I mean, he was the type of figure I always wanted when I was a kid. Close second would likely go to Alt. Prowl... but this is a choose one type of deal, so sorry Prowl. Who would you choose? Only rule is that it must be part of your current collection. I assume the combiner debate will come up at some point... I'll leave it up to you if you consider it one bot or multiple bots. So... Who is your ONE transformer that you would keep, if all the others had to go for whatever reason?
