THEORY: The Death of Sam Sinister

Feel free to change this topic’s category if it’s in the wrong one.

This is, perhaps, my oldest LEGO-related theory, cooked up long before the rise of BIONICLE’s reputation and the expectation set in what LEGO was required to deliver, based on nothing more than the content of sets and, more specifically, the design of certain minifigures.


This here is Lord Sam Sinister, the original oppugnant of LEGO’s Adventurers theme, who battled the do-gooder archeologists as they explored fictional ruins of ancient Egypt and unearthed the deadly secrets entombed in long-forgotten and rather colorful pyramids scattered across the desert.

And this here is the barbaric Baron Von Barron, the right-handed right-hand man of Lord Sam Sinister and a skilled pilot, never seen without his malicious moustache and magnificent monocle. Take a good look at these two faces because you’ll see one of them again very soon.

These two dastardly fiends were dueled over the sands of Egypt in cars, planes, and balloons, trying to outrun the heroic team of explorers and reach the inside of the largest pyramid ahead of them to claim its treasure as their own. However, since Johnny Thunder and his friends moved on to other adventures, it is safe to assume they bested the baddies and obtained the treasure.

The Adventurers’ journeys took them to the depths of the Amazon jungle, to locate a forgotten city and stop the theft of its greatest treasure by the greedy Señor Palomar. Then they once again butted heads against Baron von Barron as he attempted to steal living Dinosaurs from a previously unheard of island, going so far as to have an entire set formed around the action of him stealing a baby T-Rex (what a villain!).

After that, the theme took a bit of a break, disappearing off store shelves and leaving most people assuming it was gone for good, until the sudden return of the theme in 2003 with a one-year release of a plethora of new sets and daring adventures to partake in, all of which pitted the party against the return of Lord Sam Sinister, and…

…here is where the theory begins. Take a look at this image of Lord Sam Sinister from 2003.


Something seem familiar? Could it be that this man, this minifigure, wielding a hook on his left hand, a monocle over his right eye, a signature moustache and still vibrantly red cheek scar is not in fact Lord Sam Sinister, but Baron von Barron mooching off his former boss’ bank account?

By all means this is Baron von Barron. He’s identical in every aspect outside of his attire, but in every set and advertisement in which he appeared during 2003 he was referred to as Lord Sam Sinister and only by that name. So what happened? Did LEGO’s designers create a minifig and LEGO’s story team just not do their research which would have taken five minutes of flipping through an old catalog?

Possibly, possibly. Or perhaps something more… Sinister.
And that’s another lifetime comedy award, thank you thank you

The theory operates like this: Lord Sam Sinister’s operation in the sandy seas of Egypt ended rather unfortunately for him, either by his own folly in the ancient tombs or by the diabolical hand of Baron von Barron. After being dogged by Johnny Thunder and his Adventurers during his dinosaur thieving expedition, he faked his death and assumed his old employer’s identity to operate in greater Asia, where the Adventurers inevitably ran into him yet again.

What do you think? Did Lord Sam Sinister simply get plasticha surgery? Is there no deep insidious plot involved with the elimination of one of the oldest LEGO villains in history? Do I need to to get a life? Make sure to let me know!


…are we sure they aren’t the same person?


They’ve existed in the same room together, so to speak.


In this set they’re both riding in the same car.


well there goes my theory

Yeah sounds pretty solid
Perhaps he was away for years at a time and was reclusive to begin with, so no one questioned his new appearance.

Both characters are famous for their changing names:

Sam Sinister (the first guy) was called Slyboots in Europe. During the Dino Island run, Slyboots became the character’s official name in both America and Europe, while the name Sam Sinister was given to his partner.

Baron von Barron (also known as Evil Eye in the UK, Mr. Hates in Germany, and Baron von Baron in some American prints) was Sam Sinister’s partner initially, but during Dino Island he was called Sam Sinister while the other character was named Slyboots.

I like the theory that Baron von Barron assumed Sam Sinister’s identity, it’s a good explanation for why the two had the same name, but the name swap actually happened before Slyboots disappeared.


But the problem is the original Sam Sinister (Slyboots) character disappeared. He’s not in any of the Dino Island sets, or any other sets outside of the initial run of the line. Baron von Barron has two partners during Dino Island:


Mr. Cunningham


Alexia Sinister

Right — his consistent “Slyboots” rename occurred outside the sets, in crossover media like LEGO Racers 2.

I miss those days.

My theory is that Sam Sinister and Barron von Baron got hit by an ancient Egyptian curse and morphed into one person, hence why he starts going wacko later on. Would explain the similarities in the later figures too.


Perhaps baron von Barron isn’t the first person this skinwalker has impersonated, perhaps there are others.


Sam Sinister’s daughter???


I don’t know the deep lore well enough to answer either way in that department, although it would certainly be an interesting discussion between her and Baron if that was the case, especially if Baron did away with his boss.


Alexia is Sam Sinister’s (Baron Von Barron’s) sister, according to LEGO Mania Magazine.

Alexia would definitely recognize that the guy with the monocle and hook hand is her own brother…unless Slyboots killed Baron Von Barron (the original Sam Sinister) after the Egyptian saga, got plastic surgery, and stole his identity!

Or no one was killed. Baron Von Barron was the only Sam Sinister and Mr. Cunningham is Slyboots with a beer gut.


Couple things to keep in mind:

  • The original Sam Sinister (Slyboots) was referred to as Lord Sam Sinister and was the only Sam Sinister with that royal attachment to his name. In most of the original Adventurers sets in which the duo of him and Baron von Barron appears, Baron von Barron appears to be doing the majority of the heavy lifting, such as distracting the heroic party to allow Lord Sam Sinister to plant dynamite or get directly to the treasure.

  • Lord Sam Sinister’s double identity as Slyboots is reflected in the set names as well, with the release of Slyboot Car.

  • The original Lord Sam Sinister dressed in a top hat and suit, and had curly, black facial hair and menacing eyebrows. No other minifigure in the Adventurers catalog has reflected these design elements, which means it’s extremely unlikely Slyboots simply rebranded as Mr. Cunningham or any of the other side villains, but instead dropped off the map after the first wave.

Assuming she had the name Sinister from before Slyboots’ departure, I would incorporate this into my theory to say Lord Sam Sinister and Alexia Sinister (Or Sanister for some reason depending on what ad you read) were actually husband and wife, with Baron being Alexia’s brother.

Nah, there’s only one of him, he’s just moving really quickly. Y’know, like the Olsen Twin.

Uh, that’s not a good look in the face of what the magazine explicitly confirms…the words “sweet,” “home,” and “Alabama” come to mind…


I said Lord Sam Sinister, not Sam Sinister (Baron Von Barron). Read the rest of the sentence you quoted.

oh I thought that was just my double vision


very good
