I want a person to say ";Clone me" so is clones them.
workspace.Player.Archivable = true -- makes us able to clone it
local char = workspace.Player:Clone() -- clones player
char.Parent = workspace -- parents it to workspace
char:MoveTo(workspace.Player.Torso.Position) -- moves to player

you can make a simple one that when you say ":clone" it clones the player who said it but if you wanted to make one so when the player says ":clone plr", it'll be more complex and I don't feel like making it.
