Godzilla vs. Biollante
Godzilla vs. Biollante is the 17th entry in the Toho produced Godzilla film series and second in the Heisei era. In this film Godzilla's opponent is a monstrous plant creature Biollante, created by a genial though mad scientist who combined cells of Godzilla with the ones of a rose. The story is even more complicated by the activities of agents of Bio-Major corporation and a Saradian agent (Saradia is a fictional Middle East country that has its own interests in this case).
The following weapons were used in the film Godzilla vs. Biollante:
In the scene in Dr. Shiragami's laboratory John Lee (Kurt Cramer) and Michael Low (Derrick Holmes), agents of Bio-Major corporation, are armed with M1911A1-style pistols.
Unidentified suppressed pistol
In the same scene Saradian agent SSS9 (Brien Uhl) uses a suppressed pistol. It is seen only from muzzle so cannot be identified.
SSS9's backup gun is a small pistol that resembles some Beretta model.
In the opening scene three agents of Bio-Major corporation, disguised as JSDF personnel, are armed with suppressed MAC-10 SMGs.
