If you had to sell your entire collection but could keep one toy, which one would you choose to keep?

A simple question really. You can only choose to keep one.

If I had to choose, it would be my G1 Sideswipe as this was the first Transformer I ever owned and I remember quite vividly going to Kmart with my parents and being able to choose a Transformer as a reward for not biting my nails for 2 weeks. For me, it’s not about dollar value but more for the sentimental value as it is irreplaceable.

I’m interested in hearing about your favourite Transformer and the reasoning behind ‘why’ you would never choose to part with it.
