Greetings I do not know if anyone is developing a Transformer sheet, but Robert M. ( <a href="https://app.roll20.net/users/5545412" rel="nofollow">https://app.roll20.net/users/5545412</a> ) and I developed a Proof of Concept for a G.I. Joe sheet: <a href="https://app.roll20.net/join/19720466/iQuqxg" rel="nofollow">https://app.roll20.net/join/19720466/iQuqxg</a> which, I believe, he is continuing to develop. Please reach out to them... Yours curiously, Vialmada
