Sisters. Always bickering about something. (Patreon)

Ever since they were turned into twin girls, Batman and Superman just can't seem to get along, especially since they both have, like, the biggest crush in the history of the universe on Captain Marvel. Besides, Superman keeps borrowing Batman's clothes without asking, while Batman snuck a peak at Superman's diary, and... well, in the end of every issue, they always ended up hugging and crying.
