These Battels are presented in the style of professional wrestling events, with the costumed performers playing the roles of giant, city-crushing monsters similar to Godzilla and Gamera.

While a student at School of the Museum of Fine Arts, Boston, Rand Borden and peers who grew up watching Ultraman decided to make kaiju suits for a short film.

[2] The first character created was Midori no Kaiju (Japanese for "Big Green Monster"), which Borden assembled from upholstery foam coated with latex.

The Battel featured Midori No Kaiju, as well as Atomic Cannon, Powa Ranjuru, Force Trooper Robo, Taro "The Mouth" Fuji's commentary, and Anthony Salbino's construction.

The first full-scale Kaiju Big Battel event was held in March 1995 in Boston, Massachusetts at the School of the Museum of Fine Arts.

[3] The earliest performances in other cities included matches with other troupes of costumed wrestlers at venues such as Fort Thunder in Providence, Rhode Island.
