A new pair of NIKE shoes to honour/homage an American basketball player (Clalvin Johnson), has several Transformers themes to it because the nickname of that player is "Megatron".
NIKE appear to have avoided any need for licensing or permission from Hasbro, by using a unique symbol that us fans would recognise as being similar to a Decepticon symbol, plus a purple grid colouring like Gen1 packaging, and the name "Mega Tron" inside the shoe.
(the number 81 is his shirt number, and CJ is his initials)


I wonder if this technically counts as a third-party item... if Hasbro weren't consulted or knew that they had no grounds to stop it.
