StarterCharacter for a specific user?

So I have a question, I am trying to make a StarterCharacter that only I can have in my game that I'm working on, I have gotten it to work using this code below, but the problem is that when anyone in my game resets, they will respawn as my character model as well, is there anyway around this? and if so can they help me by sharing the code as I am really new to this. Thank you! Here is my code in ServerScriptService at the moment:

local Avatar = game:GetService("ReplicatedStorage"):FindFirstChild("Jotaro").StarterCharacter

game.Players.PlayerAdded:Connect(function(player) if player.Name == 339048720 then local PlayerAvatar = Avatar:Clone() PlayerAvatar.Parent = game:GetService("StarterPlayer") PlayerAvatar.Name = "StarterCharacter" wait(0.1) Player:LoadCharacter() end end)

just do it in a local script

so in StarterPlayerScripts, put this:

local Avatar = game:GetService("ReplicatedStorage"):WaitForChild("Jotaro"):WaitForChild("StarterCharacter")
local plr = game:GetService("Players").LocalPlayer

if plr.UserId == 339048720 then
	local clone = Avatar:Clone()
	clone.Parent = game:GetService("StarterPlayer")
	task.wait(0.03)
	plr:LoadCharacter()
end
