Your normal life as a human is over. Your body is destroyed and can't be recovered (nor buried) but you now are given a second chance to live again, this time as a Transformers figure. Your soul has possessed a TF toy from hastak and made it animate, thus you can move, talk, etc. as you wish. It doesn't matter who it is or what line it's from (MPM, SS, MP, CHUG, etc.), what matters is what toy you choose to be for the rest of your new life. What figure are you reborn as???
The SS Bumblebee baltmatrix smashed to bits. Being a tiny piece of plastic after a fulfilling life as an actual person is not a rational or sane choice in the slightest. I'm happy with just one chance, thank you very much.
Whatever figure has articulated fingers, opposable thumbs, ankle tilts and doesn't come apart into pieces.
if we animate the figure like toy story with all the mobility of a human, Titan class Trypticon if not Haslab Unicron or Titan class Metroplex
You did specify that we're coming back as a Transformers FIGURE which rules out most or the semi-paralyzed G1 guys who I would pick. So...I guess that I'd pick Beast Wars Ultra class Rampage. The beast mode and tank mode might actually allow for some mobility and it just looks cool as hell.
Probably Animated Blurr. I am a big runner and my body has changed to a runners build and I think TFA Blurr really represents it.
Would for sure be the build a figure Transmutate from the 10th anniversary Beast Wars line. I would then hop from collection to collection just haunting peeps.
