    local newChar = hollow:Clone()
    newChar.Name = "StarterCharacter"
    newChar.Torso.TheTorso.BrickColor = BrickColor.new(color)
    newChar["Left Leg"].LLeg.BrickColor = BrickColor.new(color)
    newChar["Right Leg"].RLeg.BrickColor = BrickColor.new(color)
    if SP:FindFirstChild("StarterCharacter")~=nil then
        SP:FindFirstChild("StarterCharacter"):Destroy()
    end
    newChar.Parent = SP
    plr:LoadCharacter()
