Like Legends of Tomorrow: Let's build a Team of Misfits composed of Heroes, Neutral Characters and Villains from Alternate Timelines (and Alternate Earths in this case). Let's also pick the main villain for the first story arc.
The Instructions are:
[1] The Captain that put the Team together has to be known Time Traveler or a Dimension Traveler (from any reality). In the show it was Rip Hunter. Other examples are Legionaries, Booster Gold, Per Degaton, etc.
[2] The team should have between 5-8 members. you can add 3 recurrent allies
[3] You can also pull characters from NCM (Non-Comicbook Media): the Arrowverse, DCUAOM, TT show, Smallville, BATAS, you name it.
[4] At least 2 out 5 / 2 out of 6 / 3 out of 7 / 3 out of 8 characters should be villains or antiheroes (as listed in this wiki| if in this wiki).
[5] There has to be a Tech Wizard
[6] There has to be an AI (not counted as a member). In the show it is called Gideon.
[7] The positions are (1) Captain/Leader, (2) Second in Command/Field Leader/Combat Expert, (3) Technician/Mechanic/Gadget Maker/Programmer, (4) Tracker/Hunter, (5) Enforcer/Brawler/The Muscle (6-7-8) Anyone if needed.
If you want to deviate from any single instruction. You're allowed to skip one and please justify it.
[8] The main villain of the first story arc can be paired with an evil organization of your choice, even when the villain isn't part of it in any continuity.
[9} The Allies should be from either New Earth or Primer earth continuities
[10] If you choose 7 or 8 Team members, at least 1 (max 2) is /are traitor(s) and will betray the team before the end of the story arc.
Please keep it fan-fic free. Also please try to explain your reasoning utilizing DC official canon interpretations, characterization, powers and traits. Please don't create alternate versions of a character and give them powers they didn't have in DC authorized versions. There are sufficient versions of beloved characters across Elseworlds, Alternate Timelines and parallel Earths to pull from.
