"Ben 10" Omnitrix Trivia Quiz

Answer: Fourarms

We learned the name of Fourarms's species in the episode "The Galactic Enforcers." There is also a special appearance made by a Tetramand in the episode "Grudge Match." Look closely at the monitors when Slix is telling Kevin and Ben that he controls the ship, and you'll see a Tetramand with an eye patch.

Answer: Grey Matter

In the episode "A Small Problem" Ben was trying to turn into Ripjaws to sneak on to a ride, but got turned into Grey Matter. Later, he was abducted by Howell Wayneright, who was at the time obsessed with finding aliens. Grey Matter is small, which lets him get into machines and operate them. His species, Galvans, have high intelligence. He also can stick to many surfaces quite easily.

Answer: Cannonbolt

Cannonbolt is the first new alien to appear on the Omnitrix (by new alien, I mean outside of the original ten aliens). His power is rolling himself in a ball and then rolling at enemies at high speeds. His weight makes the attack really powerful, but when not in his ball form, also makes him quite clumsy.

Answer: False

In the season two finale, Ben does use the Master Code to give him use of any alien anytime, and for however long he wants, but he does so by accident. He zeroes out the Master Code just before Kevin removes the Omnitrix from his arm. Later on, when Ben gets the Omnitrix back, he forgets he zeroed the Master Code. Because Ben's next transformation was not the one he wanted, we can assume he does not know the Master Code anymore.

Answer: Upgrade

Upgrade can also fire positronic energy beams from his eye, and create hard-light constructs out of this same energy. He used his ability to get inside machines to defeat Rojo in the episode "The Alliance."

Answer: XLRBolt

In this episode, Ben messed with the Omnitrix and broke it, causing the faceplate to be removed. Dr. Animo soon found the faceplate and used it to mutate people. Ben had to stop him, but the alien transformations ended up being combinations of two aliens that seemed as though they were opposites.

In this episode, we learned that Heatblast may be able to survive water, if he can get out quickly enough.

Answer: Ghostfreak

In this episode, Ben accidentally triggers the Master Code, and ends up with the ability to transform into any alien he wants, whenever he wants to, and for however long he wants. When Vilgax and Kevin teamed up to get the Omnitrix, Ben used his new abilities to save himself. He used every alien form except for Ghostfreak in this episode, which may mean Ghostfreak is gone for good.

Answer: True

In the episode "Ghostfreaked Out" Ghostfreak breaks out of the Omnitrix, and he removes his second skin. However, because of this, he was vulnerable to sunlight. It is possible that when alien DNA was gathered for the Omnitrix, some aliens were altered so weaknesses like sunlight were not an issue.

Answer: XLR8

XLR8's abilities give him enhanced speed. He is first seen in the first episode of the series. He is vulnerable to magnetic pulses. He isn't as strong as the other aliens, but his speed makes up for this.

Answer: Heatblast

When Ben caught a cold from being trapped in an ice cream truck, the effects affected his aliens as well. Four Arms was least affected by Ben's cold, as he develops hives on his underarms, and he sneezed large amounts of mucus. Wildmutt went blind since his nostrils were clogged up with mucus, and he had no eyes to see with.

Heatblast's powers over fire reversed, giving him control over ice, which he used to cool down a nuclear reactor.
