To Hasbro, no one is too young or too old to play with a Transformers robot, watch a Transformers television show or play a Transformers video game.

The toy maker started the Transformers franchise with a Japanese partner in 1984. The concept — robots disguised as everyday objects — was originally aimed at 5-year-old boys. But as those boys have grown up and had children and even grandchildren, Hasbro has expanded the brand into other media and added new toy lines to appeal to everyone from toddlers to adults.

Take Rescue Bots, for example.

The main Transformers brand contains mature themes, with big robots battling for control of the planet. To engage children ages 3 to 7, Hasbro introduced Rescue Bots in 2011, featuring toy robots as first responders.

“The goal there is to take what you have and bring an age-relevant message, which is to get away from the battle and the fighting and focus on the heroic nature of Transformers,” said Jay Duke, global vice president for the Transformers brand at Hasbro.
