This episode is meant to be a commentary on drug use, and steroid use in particular. It's also the last chronological appearance of Bane, reflecting how the actor who played the character in _Batman and Robin_ (1997), Jeep Swanson, died as a result of steroid abuse.
During Terry's faceoff with the three robbers, Mason is wearing a balaclava with superficial similarity to Bane's old wrestling mask.
When Jackson Chappell fights Batman, his black outift, complete with a tank-top, is very similar to Bane's old costume, sans mask.
