The Venture Bros. fit neatly in a world where dense in-universe continuity is more popular than ever. The show began life as a one-note Johnny Quest parody but has blossomed into a sardonic tribute to everything comics, TV, movies, and games steeped in the ever-present threat of failure. Failed super-scientist Dr. Thaddeus "Rusty" Venture's anxieties and traumas from traveling the world with his adventure father have been passed down to his twin sons Hank and Dean, who are living the same reality with their own bodyguard Brock who does what he can to protect the family from a supervillain union called the Guild of Calamitous Intent. The Guild and the OSI pride themselves on bringing the one thing that the superhero/villain dynamic lacks: bureaucracy. And that's not even the tip of the Venture's iceberg.
The show prides itself on having more characters, events, and general stuff happening at any given moment than you could ever be expected to remember off the top of your head. If that's your flavor, then you probably have a decent enough time telling your Monstroso apart from your Henry Killinger. There have been several startling reveals and long con story arcs that unfold in mind-blowing ways over the course of the Venture Bros. first six seasons, and I decided to go digging for some of the most profound in time for the seventh season premiere. Go Team Venture!
One of the treats of season 4 was watching the newly formed Revenge Society run through the Rolodex of New York City's worst villains ever, but two of the more memorable ones were introduced earlier than we may have realized. Their names show up on file cabinet doors in "Pomp and Circutry," a whole three episodes before they're introduced officially in "Bright Lights, Dean City." It's a blink-and-you'll-miss-it reference, but it's enough to prep you for characters that share the same space with others like Lyndon Bee Johnson and Brick Frog.
The Monarch is Dr. Venture's (self-professed) archvillain for reasons that still haven't been revealed yet, but there's at least one hero out there who fears him regardless. Captain Sunshine is a solar-powered Superman clone who actually believes the scrawny trust fund brat of a Monarch is invulnerable, and it all starts with a subtle comment near the end of the show's first season. "Have you sent the charred remains of Wonder Boy to his beloved Captain Sunshine?," Monarch asks his henchmen from jail during the season one finale "Return to Spider-Skull Island." We never hear about Captain Sunshine again until the third season premiere "Shadowman 9: in The Cradle of Destiny" where a flashback reveals The Monarch and Dr. Girlfriend meeting at a villain party for the first time and talking about how Sunshine "thinks I'm invulnerable to this day."
The trick comes to a head in the next season when we finally meet Captain Sunshine (Kevin Conroy) in "Handsome Ransom," where it's revealed that this slab of sun-powered granite actually believes the Monarch is invulnerable. We also find out that Monarch actually slew Sunshine's sidekick Wonder Boy in a drunken rage before the show ever began. The reason's unclear, but he got hit with a pretty bad sunburn for his trouble.
Brock Sampson is nothing if not one of the most ruthless bodyguards in television history. Look no further than his encounter with Devil Bird from the season 3 episode "The Doctor Is Sin," where he runs Devil Bird over with his car.
Brock apparently kept the costume afterward because he gives it to teammate Shore Leave during the season 5 episode "Bot Seeks Bot" as a disguise to get into a Halloween party.
When Rusty comes into a lot of money after the events of "All This And Gargantua-2" and moves the whole family to New York, they meet a group of bootleg Avengers called the Crusader's Action League, led by a very Captain America-esque hero named Stars and Garters. True to his nature as a parody of Flash Tompson (named Tosh Tompkins) from the Spider-Man comics, by day he's a student at Stuyvesant University who bullied Jared, who is the Brown Widow that we meet back in season 4's "Bright Lights, Dean City."
It's an incidental detail that hasn't been expanded on yet, but since we'll still be in New York for season 7, I'd be surprised if it doesn't come up one way or another.
Not being able to "arch" Dr. Venture really depressed the Monarch back in season 3. It got to the point where he had to arch different villains, including a pink hero named Dr. Dugong aka Douglas Ong. They first meet during "Tears Of A Sea Cow" where Monarch and Dr. Ms. The Monarch are attempting to foil his plans to unite humans and fish; Monarch winds up blowing his head off with a laser when he randomly thinks of Dr. Venture "abandoning my hatred."
Dugong turns out to be the brother of Chester Ong aka Wide Wale, the mob boss and major antagonist of season 6 who is attempting to shake up the newly reformed Guild of Calamitous Intent. Both Douglas and Chester were mutated while trying to find a cure for cancer using cuddle fish DNA, which turned Chester into a whale-sized man and Douglas into a pink dugong. Chester spent the majority of season 6 manipulating Dr. Ms. The Monarch in her new position of head of the Guild because of his hatred for the Monarch for killing his brother, who is actually still alive and in Guild custody.
