I have made a few Transformable Kreon / Brick bots that can transform quite similar to the G1 toys. I have a God Ginrai where the God Bomber separates from Super Ginrai to make a separate robot. Super Ginrai has a body frame that can open up in to a battle station but no trailer mode yet. Small Kreon Ginrai can turn to truck. An Overlord that splits and transform to a tank and jet. And a Star Saber and Victory Leo combo.
