If you could go back in time and give a Transformer to a younger version of yourself, what would it be?

Let's establish some ground rules:
Younger means being a kid, let's say around age 12, but definitely no older than 18.
The reason you are handing it to yourself is because it's something you would actually enjoy back then.
It has to be something you have in your collection now. Ideally a more modern toy that didn't exist when you were a kid.

My answer would be Siege Jetfire. MP-level play features in a durable CHUG toy. I reckon a 12yo me would've loved that toy to bits.
