This is a set of mêlée accessories for the Legends Megatron (2013) figure! In here you have a pickaxe and flail to fit in with his early roles as a miner and gladiator respectively.
Both accessories use 5mm peg handles and are compatible with a wide selection of figures.
This model has been successfully tested in Hot Pink Strong Flexible Polished. You might want to use an adhesive to ensure the halves of the spiky ball sticks together.
