SPOILER WARNING: This article contains major spoilers for "Tribute," the latest episode of Arrow.

Bruce Wayne wasn't the only DC Comics character namedropped in "Tribute," the latest episode of Arrow. Another -- albeit much more obscure -- character got a quick mention, too: Python.

The episode saw Felicity quizzing Curtis "Mister Terrific" Holt about his freelance coding work. At one point, while talking programming languages, she asked, "Python?" to which Curtis responded, "The supervillain?"

There are two DC characters who use "Python" as their supervillain name: Jacob Bernstein, an enemy of Wesley Dodds' Sandman, and Black Python. At first glance, neither character warrants much of a mention, since both characters appear only five times each in DC Comics' long history. However, both have upcoming ties to the Arrowverse that beg a closer look.

For instance, in Bernstein's case, Sandman has been teased for DC's Legends of Tomorrow. Last month, executive producer Marc Guggenheim shared a set photo of a mask that looks suspiciously similar to Dodds', which suggests the Golden Age Sandman may be on the way to the time-jumping series. It wouldn't be a stretch, then, for Bernstein to appear alongside him, even in a quick cameo role.

On the other hand, Black Python debuted in 2011's Freedom Fighters #3. The eponymous Freedom Fighters will be important to this year's Arrowverse crossover "Crisis on Earth-X," which pits the heroes against their evil Earth-X doppelgangers. The Ray -- a member of the Freedom Fighters, per his upcoming animated CW Seed series -- will play a role in the four-show crossover. As such, it's possible that a villain like Black Python could aid these Earth-X villains or perhaps even cross over to Earth-1 with them, though the latter scenario is less likely.

At this time, no Python has been announced for an Arrowverse show, so the namedrop could simply be a fun Easter egg for DC Comics fans. However, there's just as a good a chance that the reference could pave the way for a villain with that name to show up in that universe down the line.

Starring Stephen Amell as the Emerald Archer, Arrow airs Thursdays at 9pm ET/PT on The CW. The series also stars Emily Bett Rickards, David Ramsey, Willa Holland and more.
