How do i edit the standard character scripts?

I want to make my own starter character but i cant even find out where the game is getting the starter scripts that they insert into your character from.

If anyone knows how i can edit these any help would be appreciated, thank you.

you cant edit another script with a script

but

that does not mean there is no solution,

STEP 1:

delete the default scripts with a script in StarterCharacterScripts

wait()
script.Parent.DEFAULTSCRIPT1:Destroy()
script.Parent.DEFAULTSCRIPT2:Destroy()
script.Parent.DEFAULTSCRIPT3:Destroy()

note that i give a wait() function to give everything to load in before destroying stuff so that we dont accidentaly destroy nothing!

STEP 2:

clone your brand new custom scripts from ServerStorage (or ReplicatedStorage) with the same script

wait()
script.Parent.DEFAULTSCRIPT1:Destroy()
script.Parent.DEFAULTSCRIPT2:Destroy()
script.Parent.DEFAULTSCRIPT3:Destroy()
------------------------------------------------------------
local customscript1 = game.ServerStorage.Script1:Clone()
local customscript2 = game.ServerStorage.Script2:Clone()
local customscript3 = game.ServerStorage.Script3:Clone()
customscript1.Parent = script.Parent
customscript2.Parent = script.Parent
customscript3.Parent = script.Parent
