Shock footage showed fans of both squads throwing punches in front of Surrey Quays station before their teams locked horns in the fourth round of the FA Cup.
Police called the fights "some of the worst football violence" they'd ever seen as they appealed to the public to help identify the men.
During the brawl Everton supporter Jay Burton was slashed across the face with a knife.
Before the match the violence quickly escalated as dozens of other fans joined in within seconds of the brawl breaking out on January 29.
According to more unverified footage, at least one supporters' coach was damaged by Millwall fans during the chaotic scenes in London.
And Everton fans were also recorded gathering outside a pub containing Lions supporters as police blocked them from crossing the road.
Police officers, supported by a mounted patrol, quickly intervened and had to use batons to separate the two groups.
This was some of the worst football violence we have witnessed for a very long time
A 27-year-old man was arrested on February 6 on suspicion of wounding with intent, attempted grievous bodily harm (GBH) and violent disorder yesterday.
He has been bailed to appear at a Central London police station on Thursday, February 28.
Detective Sergeant Matt Simpson, from the Met's Public Order Investigation team, said: "The disorder which broke out on Saturday, 26 January was some of the worst football violence we have witnessed for a very long time.
"It left one man with a life-changing injury to his face, and caused chaos in the streets.
“A post-incident investigation was launched, through which we are working hard to identify those involved in this completely unacceptable and shocking behaviour."
Police are now appealing to the public to help identify the 12 men in the photos.
Simpson said: "We have today released images of 12 individuals we are attempting to trace in connection with this incident.
"The public can play a huge role in helping police, especially by assisting us in identifying wanted individuals. You are our eyes and ears.
“The public have undoubtedly helped us bring many wanted offenders to justice in the past, and we hope they can assist us in this investigation."
Anyone who recognises the individuals in these images is urged to call police on 020 8246 9386 or Crimestoppers anonymously on 0800 555 111.
