Breaking the Fellowship

Our heroes are a force of nature. United, there is nothing in this world that can stand against them. Divided...well...things aren't going so well.

Whether due to a plot device, a scheme by the villain, or simple internal strife, the heroes are separated. They may be scattered all over the world, they may just go their separate ways, but the point is they are no longer a team. It may take multiple story arcs to get them back together, or they may never get back together. Even if they do get back together, their separate adventures and tribulations will have caused them to change and drift apart in ways they could not have foreseen.

When this happens, expect it to be the Belly of the Whale, even the Darkest Hour. No group would ever do this willingly, because you Never Split the Party. Expect the episode where this happens to be a Wham! Episode. If they meet again, they might have a few episodes of Putting the Band Back Together. If they don't... Nothing Is the Same Anymore.

Note: For it to count as this trope, it should be a whole arc, not just one or two episodes. If just one character leaves, or it lasts for a very short time, it falls under other tropes.

Compare Let's Split Up, Gang!, where they split up, but intend to find each other again later, Party Scattering, where they are split up involuntarily and sent on Solo Sequences by an external force, and The Fellowship Has Ended, where the split-up becomes permanent.

Video Games

You get a couple of them back, but the others refuse to come back for various reasons (can't leave their work, won't work with Cerberus even for you). In Mass Effect 3, all of the surviving squad members from the first game (with the likely exception of one who seems set to nonetheless be an important ally) end up back with you.
 * Final Fantasy VI: The entire second half revolves around tracking down each member of your old party and rallying back into the fight.

 * Happened in Order of the Stick following the battle of Azure City. Eventually they got back together, but with all party members having gone through a lot of Character Development. The arc was even titled "Don't Split The Party".
 * Also happened in the backstory to the "Order of the Scribble," the Order of the Stick's predecessors in confronting the dangers of the Snarl. They never reunited and, at least in the case of Girard Draketooth, hated the others Soon Kim beyond rational thought.

 * Gunnerkrigg Court had the group formerly containing Surma, Anthony, Eglamore, Anja, Donald and (presumably) Brinnie. By the time the comic starts, the group has been broken—Anja, Donald and James remained in the Court as teachers, Brinnie's whereabouts are unknown (appeared only in flashback) and Surma and Anthony in Good Hope Hospital, with Surma as a patient and Anthony as the doctor. Surma ended up with Carver instead of Eglamore and the Court's three lost contact with Brinnie and didn't know where Surma and Anthony were (Anja apparently discovered that Surma died only when Annie was transferred to the Court). Why they broke up on such bad terms is yet unknown. The only plausible apple of discord revealed so far was Reynardine possession incident.
