Key Facts

1st cameo appearance of Jason Todd

2nd cameo appearance of Killer Croc

⚠️ Debatable Firsts: this issue is cited as the first full appearance of Killer Croc but there is no difference in his depiction as a gangster in a trenchoat and fedora as first seen in Detective Comics #523, released one month before #357. In Detective Comics #524, he is revealed to have crocodile features for the first time

It should also be noted that this version of Jason Todd is not visually accurate to later versions and his origin is retconned in Batman #408

CGC recognizes this issue as the first full appearance of both Killer Croc and Jason Todd
