Ultra Monster Series

The Ultra Monster Series(ウルトラ怪獣シリーズ, Urutora Kaijū Shirīzu) was a toyline started by Bandai in 1983. It featured kaiju from various Ultra Series.

History
Since 1983, figures were made in Japan with considerably hard vinyl. Then, in 1994, production of toys moved to China. Softer vinyl started to be used for the figures. In May 2000, it was decided for the products to be reissued as the number of characters has increased tremendously--36 Ultra Heroes and 140 Monsters. A total of 30 heroes and 70 kaiju figures were reissued with new packaging and a new price. In 2013, this line was replaced by the Ultra Monster 500 Line.
