Wow. I dunno why I'm making this offer, but... I will give you my 5 Japanese imported 1/144 HG Gundam Model kits for you MP-1 Prime or your Optimal Optimus. I used to have Optimal Optimus when I was 12
aha Sorry, I don't do HG anymore. I don't really do model kits anymore anyways, but I would like to go back for a dip one day. Maybe MG or PG. I started my TF collection during BWs and Optimal Optimus and TM2 Cheetor were a must for me. Still have them.... just not for sale. 20th Anniversary Prime is staying with me. He's the only MP I'll be holding onto.... and Jazz when he gets announced/released.
They had the G1 transformers much larger than they should have been...... If you compare Optimal to the cave people and cheetors beat mode (its the same size as the actual animal) hes about average by G1 standards but in the show he is still on the tiny side
