Although cloning a user is possible,
Is there a way to insert a character directly from InsertService or such?
local playerId = 1222926 -- My own id for example... game.Players:GetCharacterAppearanceAsync(playerId).Parent = workspace
This bit of code grabs everything that the user is currently wearing from Body colors to clothes, hats, faces, headmeshes and body packages.
However, it will not create a character for you, you are required to create your own humanoid and stuff.
