Crazy Ben Tennyson is an alternate personality of Ben Tennyson and the main character of Ben 10: Stupidity Force, and a main character in its sequel, Ben 10: Stupidity Force: End Of Omnivangelion: Future, alongside Ben Prime and Muslim Ben. He is usually referred to as Ben in BTSF, and is later on referred to as CBT (for either Challenged Ben Tennyson or Crazy Ben Tennyson) in BTSFEOOF.


Crazy Ben appears similar to his 16 year old self in Ultimate Alien, wearing the same green jacket and blue jeans. He constantly wears a pair of black sunglasses, from the DEAL WITH IT meme. His Omnitrix appears similar to his Ultimatrix from his days in BTSF.


Crazy Ben is eccentric, immature, and extremely impulsive. He is not particularly interested in his environment around him, and instead usually focuses on his impulsive needs such as doing stupid things with Eggy or his hunger.

Crazy Ben has a love of randomness and internet memes, and usually uses his own powerful aliens to act on this love, adding to his bizarre behavior.

Despite his behavior, Crazy Ben is dedicated to protect friends, family and the innocent, and will use any tool at his disposal to ensure that, even in bizarre ways.


Ben 10: Stupidity Force

Crazy Ben was created during Ben Prime's fight with Clancy, as the virus infected Ben's system caused his personality to change radically. Crazy Ben awoke with no memory of his history, and slowly learned it throughout the course of the show. While trying out Alien X, Crazy Ben accidentally consumes Celestialsapien blood, granting him his unconscious reality bending abilities, which influence the rest of the series. Crazy Ben also unlocked multiple bizarre aliens, and evolution types, as the show progressed. Crazy Ben also fought against multiple new villains. Crazy Ben eventually adopts Eggy, a small white bird from Angry Birds, who becomes his closest friend.

During the season finale, Crazy Ben's personality is "cured" as he converts to Islam with the guidance of Kevin, creating Muslim Ben. As Muslim Ben walks up to the altar, Ben collapses, as Crazy Ben and Muslim Ben agree to reset the universe to allow Ben Prime to live a normal life.

Ben 10: Stupidity Force: End Of Omnivangelion: Future

Crazy Ben awakes in Ben while he uses Ek to fight off Juemungousaur, taking over his body briefly. Crazy Ben later on reveals himself as an alternate personality to Ben in the bathroom, where he reveals the source of his enemies and bizarre aliens, and later on reveals Muslim Ben as well, to Ben Prime's surprise. Crazy Ben also discovers he can transform into aliens independently from Ben. After defeating their first villains together, the three team up to fight returning villains from BTSF and new villains as well, in increasingly absurd scenarios.

In Ben 10 Vs. The CEO of Racism, Crazy Ben converts to Judaism after depression from almost losing the case, although it does not cure his behavior.

Powers and Abilities

Crazy Ben possesses regular human abilities, however he also possesses the ability to subconsciously manipulate reality due to the Celestialsapien DNA within his bloodstream. Crazy Ben has not yet learned to control this ability, which so far mostly generates villains for him to fight.

As an alternate personality, Crazy Ben seems to have limited influence on the environment around him. Besides his ability to transform into aliens, Crazy Ben can be seen and interacted with with certain characters besides Ben, such as Eggy, and can also manipulate objects to some degree.


Crazy Ben possesses his Ultimate Alien Ultimatetrix, giving him access to all of Ben's past and future forms, along with his BTSF forms. The Ultimatrix has been affected by his various adventures, also granting him new evolutions such as Infinite Forms, Hat Forms, Viking Forms, Omni-Enhanced Forms, and Omni-Kix Forms.

Generally, Crazy Ben will prefer to use his unique BTSF forms or BTSF evolutions of his aliens.
