The Character Customizer lets the player customize his or her own character using parts from Characters that the player has already collected and unlocked by paying the price in Studs. In sandbox mode that isn't possible yet. Custom characters can be assembled from the following parts:
- Hat (Optional)
- Hair (Optional)
- Cape (Optional)
When selecting parts from the list, click and hold to drag the list back and forth, in order to see more than just the 13 shown (if you have unlocked more than 13 of that particular part).
Characters created using the Character Customizer do not inherit any special abilities from the parts they use (unlike in other LEGO games). Once a custom character has been created, the player can then become that character at any time by selecting "Custom A" from the Character submenu of the Models menu. The player can also spawn that custom character as an NPC by dragging it from that menu into the world, however, custom characters have no behaviours associated with them, and will just stand there, rather than wandering around.
