Members of the rival Comanchero and Hells Angels bikie gangs will face separate court hearings following a number of drive-by shootings in Melbourne.
Police charged eight men after raids across Melbourne on Tuesday night, during which guns, explosives and cash were seized.
The raids came a day after the Hells Angels Seaford clubhouse in the city's south was sprayed with bullets.
Hells Angels member Dennis Basic, 33, of Frankston, appeared in the Melbourne Magistrates Court on Wednesday charged with 13 offences, including making explosives and illegally possessing seven guns.
Deputy Chief Magistrate Jelena Popovic was told the members of the two gangs would require separate dates for their committal mention hearings.
Comanchero members Gemino Aloia, 26, of Glenroy, Bemir Saracevic, 26, of Cranbourne North, Emir Jaha, 27, of Mt Martha, and Mark Balsillie, 29, of Gladstone Park also faced the Melbourne Magistrates Court on Wednesday.
Additional police and security officers were present in the court room and outside the building.
Basic's charges were adjourned until December 20, while the other four men were remanded to appear on the previous day.
None of the five applied for bail.
Police say the Seaford attack was in retaliation for a suspected Hells Angels shoot-up of two businesses owned by a rival Comanchero member.
High-powered military weapons such as AK-47s or M1 carbines were used in both shootings, police say.
Also charged after the raids are Bashkim Gashi, 30, of Dandenong North and Mohammed Khodr, 26, of Balwyn North.
All three are expected to appear in court on Wednesday.
A ninth man, aged 22, was charged late on Wednesday with drugs, weapons and explosives offences.
Police said the man, with alleged links to the Hells Angels, was arrested in Carrum Downs by Special Operations Group officers.
The man, from Carrum Downs, has been bailed to appear at the Frankston Magistrates Court on November 27.
