Transformers Cybertron - Cybertron Primus Electronic Action Figure
[B000G01ABM / B000FVZI06]

Mighty creator of the Transformers race, both Autobots and Decepticons owe him their loyalty as his children. He is as old as the universe itself, and matched in power only by his twin brother, the evil Unicron. Primus is the Lord of Light--a pure, natural force of order, strength, and peace, committed eternally to the struggle against chaos, destruction, and the ever-advancing darkness of Unicron. Change the incredible supreme-sized Primus figure from mighty Cybertron protector to battle station and back again! Omega Lock and Cyber Planet Key activate cool features, including shoulder-mounted stellar converter cannons, pop-up forearm-mounted omega cannons, and power-up lights and sounds!

Requires 2 AA batteries (not included) and 2 button cell batteries (included).
