tl;dr version



1. You can only get Batman drops from the Batman REM.

2. The distribution of rolls in the Batman REM is *NOT EVEN*, unlike the Pink REM where your chance was equal for getting each of the healer girls.

3. The drop rate of a gold egg (DW/DL Batman) from a collab REM has historically been around 10-12%. That means you have a ~90% chance of pulling a silver egg (Robin, DD Batman, Catwoman) and a ~10% chance of pulling a gold egg (DW/DL Batman).
