Hasbro has made a takeover offer for their rival Mattel. The deal would bring the two biggest U.S. toy makers together.

The terms haven’t been revealed and the deal may go nowhere.

Hasbro has properties such as Star Wars, My Little Pony, G.I. Joe, and Transformers as well as the Marvel toy license while Mattel has Monster High, Masters of the Universe, Hot Wheels, Fisher-Price, Barbie, and the DC Comics toy license.

When it comes to board games, Mattel has properties such as Uno, Apples to Apples, and Pictionary. Hasbro has games such as Monopoly, Battleship, Operation, and more.

Mattel hasn’t been doing well this year and has a market value of $5 billion while Hasbro’s stands at more than #11 billion. Mattel shares have fallen 47% this year while Hasbro has gained 18%.
