Top Five Month continues (check here to see an archive of all the top five lists featured so far) with this suggestion by newscott on the Top Five Suggestion Thread on the Comics Should Be Good forum!
So let's look at the top five teams with none of the original members on it (I'm not counting instances where the name of the team was just used by a totally separate group - I mean a group where the team stayed the same but just slowly changed membership until no original members were left).
5. New Titans post #100
This one depends on what you think the status of Speedy is as an original member of the Teen Titans. I vote no. The guy wasn't on the team until the fourth issue of their SERIES, let alone their early Brave and the Bold appearances, so I vote he doesn't count as an original member.
And if he doesn't count (I'll count Wonder Girl as one, because she was in the book when they first called it Teen Titans) then the first time the Teen Titans were without an original member is after Nightwing and Starfire's wedding fell apart in New Titans #100. Roy was the senior member of the team for the next year or so of stories, until Donna rejoined the team.
4. Masters of Evil circa Avengers #270
Astonishingly, it took until the Under Siege storyline for a Masters of Evil team to show up without an original member.
Guess which member was consistent for each incarnation of the team UNTIL Under Siege!
3. The Defenders circa #124
This was a weird time for the Defenders.
I love me some Beast, but I dunno if I would ever build a superhero team around him.
2. The Outback X-Men
Technically, there was time when Cyclops was away and Angel had left the group that the team was without any original members, but eh, Professor X was still there, so I think it's best just to say the Outback Era.
1. Cap's Kooky Quartet
The prototypical "brand new team" team.
The book that, if done today, would have people writing stuff like "This isn't the Avengers I know!"
The more things change...
That's the list!
