Vreedle Brothers

The Vreedle Brothers, Octagon and Rhomboid, are a family of clones who first appeared in Ben 10: Alien Force.

Ben 10: Alien Force
They first appeared in Vreedle, Vreedle where they were appointed by Baz-El to return Ship to him. As Julie doesn't trust them and wants to keep Ship anyway, they start turning violent causing Ben to attack them. After Ben won the tribunal upon appealing to Judge Domstol, Baz-El tried to stop the Vreedle brothers only to be shot by them (though he regenerates few minutes afterward). Ben and Kevin managed to fend them off.

In Busy Box, the Vreedle Brothers return to claim a powerful device known only as the Naljian Destructor (it appears to have similar powers to Ship, since it, too, can create a robotic version of what ever it sees; however, unlike Ship it can copy anything upon sight instead of only being able to turn into already mechanical objects upon contact) and try to sell it to the highest bidder. They managed to take the Naljian Destructor and adapted to their way of causing destruction. When the Naljian Destructor starts acting on its own, the Vreedle Brothers returned it to Earth to cause destruction there before attempting to escape. However the Naljian Destructor shoots an energy beam at the fleeing Vreedle Brothers ship which destroys it.

However, despite their confirmed destruction, the Vreedles' return in the The Con of Rath (after Kevin's "old friend" Argit informs them Ben, Kevin and Gwen are in possession of Tiffin). When asked how they survived the explosion, Octagon reveals they have been destroyed in previous explosions (stating it happens to them a lot), and Rhomboid accidentally reveals the Vreedles are all clones created by their parents, who created multiple clones of them using an expired "cloning kit" (Rhomboid also said that the "Clones" created with that kit were considered to be "spoiled", meaning the Vreedle Bros. are basically defective clones), before Octagon is forced to remind him that that information is of a "private family matter". They then try to kidnap Tiffin and hold him for ransom, but upon seeing Ben as Rath, they are forced to hire every alien in the space reststop on the spot to help them. They are defeated & thrown into the vaccum of space, where they eventually died or somebody picked them up.

They appear to know Kevin's old partner, the porcupine alien Argit, who apparently owes them money. Argit tries to pay back his debt by providing them with information on the Tiffin and earlier in the series by selling off the Rust Bucket to them bit by bit.

Ben 10: Ultimate Alien
Another set of Vreedle clones featured in The Enemy of My Enemy, apparantly having turned over a new leaf and in training at the Plumbers' Academy, under the threat of "getting whacked again" by their Father. However, their grades were so low that their father hired Argit to infiltrate the academy and change their test scores.

When Ultimate Kevin attacked, the Vreedles tried to help by using a nuclear bomb against him, unaware that the device would kill everyone in the vicinity. After Kevin left, the Vreedles were ordered by Korwak to personally detain Argit for his various crimes.

Dispite their new leaf they are soon returned to their criminal ways by their mother Ma Vreedle in the Mother of All Vreedles. Here they help their mother in her plot to drain the earth's salt water oceans to create 300 million Pretty Boy Vreedles. Gwen eventually convinced them to return to their Plumber ways and they in turn convince their mother to come in peacefully (Albeit howling mad). They also request that the team keep quiet about their involvement in their mother's actions.

Ben 10 Alien Force: Vilgax Attacks
The Vreedle Brothers working together are a boss in Vilgax Attacks. They were hired by Vilgax to retrive the energy core on Vulpin. Through the use of the player turning the brothers attacks against each other, the Vreedle Brothers are defeated. In DS version are in Encephalus IV.

Ben 10 Ultimate Alien: Cosmic Destruction
The Vreedle Brothers appear again in the game Ben 10 Ultimate Alien: Cosmic Destruction, in Paris and the Amazon Rainforest. In the first they had broken into a Museum owned by the Forever Knights to steal valuable alien technology (specifically a peice of the Potis Altiare) and were killed by Ben. They later appeared as the main boss of the Amazon level who already had the peice of the Potis Altiare there and were trying to escape from the self destructing base where they were killed again.

Ben 10: Galactic Racing
The Vreedle brothers are the announcers in Galactic racing. They deliver the story at the beginning, introductions to all of the tracks, and commentary during the races (usually just noting when somebody gets hit, goes Ultimate, or takes first place).

Cartoon Network: Punch Time Explosion
The Vreedle Brothers appear as an Assist Character, and once they're summoned they will attack everyone, even the summoner.

Powers and Abilities
The Vreedle Brothers are physically weaker than most of Ben's enemies and appear to be no stronger than a normal human. However they make up for this with a large arsenal of Alien weapons, tech, & gear. They are revealed to have a tendency to blow things up (cause property damage), which results in them having numerous run-ins with the law (including Judge Domstol, & possibly the Plumbers as well).

Weapons
The Vreedle's possess an arsenal of alien weapons, technology, and gear. This includes everything from blaster pistols, cannons, grenades, rocket launchers etc.

Immortality
As revealed in The Con of Rath, the Vreedle Brother are in fact clones created by their parents using an "expired cloning kit". This gives the Vreedle's a form of semi-immortality, meaning even if they are killed, another "set" of Vreedle clones will take their place. According to Octagon, they have been killed by explosions several times in the past (likely due to their stupidity and tendency to blow things up). Each "set" of clones appear to retain most if not all the memories of the previous "set".

Intelligence
Due to them being "spoiled"(defective) clones, they have limited intelligence, at one point being distracted by Gwen popping bubble wrap, talking and acting like alien rednecks/hillbillies, however they sometimes use advanced terms (and are able to understand their meaning). They also shown to be somewhat knowledgeable about rare alien technology & weapons). Apparently they believe themselves somewhat smarter than Appoplexians, as they were "the only creatures stupider and meaner than we are," Octagon was also able to correct Rath on one of his mixed up quotes. In The Enemy of My Enemy, they are also shown of their lack of intelligence by even spelling their names wrongly.

They are apparently well known for their incompetence; in Vreedle, Vreedle when Baz-El sues for custody of Ship and takes Ben to court, the judge criticizes him for sending the Vreedle Brothers after Ship, declaring that they are unable to capture a target alive even when told to do so.

Trivia

 * They appear to be the same or similar species to Ragnarok and Sunder.
 * Their names seem to derive from the names of polygons, octagon and rhombus specifically.
 * In the end of The Mother of All Vreedles the Vreedle Brothers turn against their mother.
