Character selection, how to load the selected character

Hey all I am new to unity and trying to figure out how to use the correct character in game play. I have successfully developer character selection screen where user selects his character from an available selection of characters. After that I save "a unique identifier" of this character in playerPrefs.

Now when the next scene starts (the actual game), I load the id from playerpref to know which character the user selected Now my question is how do I display/create/instantiate that character using its correct sprites and animations.

All the tutorial videos show creating the character and it's animation controller of an already known character from the editor. I am not sure what I need to do so this can be done based on what user selected. I need help with the thought process here

Thank you so much
