Rook Blonko

Rook Blonko is Ben's new partner after Gwen and Kevin left the team, and one of the main characters in Ben 10: Omniverse. He is a Revonnahgander from the planet Revonnah.

Appearance
Rook is tall, with periwinkle-blue colored fur, black markings on his face, and pointed ears. The middle of his face, his chest and his stomach are white. He has black stripes on his shoulders, waist, lower legs and lower arms. He carries the Proto-Tool on his shoulder and wears very durable blue-and-black Proto-Tech Armor.

Personality
Unlike Ben, Rook is more stoic and prefers to think before acting. He used to treat Ben more like a superior instead of a friend/partner as he usually addressed him as 'sir' when they first met. He now tends to see Ben as a lesser or equal being such as saying he always has to save Ben and that, "[Ben] wouldn't even be alive without [Rook's] help." Although, Ben still manages to impress him from time to time. While he is very intelligent, his lack of experience can make him somewhat naive and often the rear of Ben's constant jokes. He seems to dislike chili fries. Nowadays, he sees Ben as a friend.

Rook still has difficulty understanding his Earth expressions, and he says that he still can hardly deal with 16-year old Ben. However, in Many Happy Returns, when Ben says that he doesn't always get Rook, but finds him to be cool, Rook explains that the feeling is mutual.

Rook is shown to be formal, such as initially calling Ben "sir" or referring to Gwen as "Miss Tennyson." When Rook first met Ben in The More Things Change: Part 1, he was respectful of him, and in The Frogs of War Part 2, Kevin exasperatingly points out that he's "so polite."

Generally speaking, Rook is open-minded and gets along with everyone, though there are certain individuals that push his patience to the limit. He does not like the Vreedle Brothers, due to them destroying the Plumber Academy. He also has to resist an urge to hit Pax.

Powers and Abilities
Rook is highly skilled in combat, combining the use of his Proto-Tool with hand-to-hand combat to disarm opponents. Through the use of hand-to-hand combat, Rook was able to fight with Ester, as well as take on and defeat multiple enemies at once even when weakened.

Rook is a master in terms of strategy and battle tactics. He also provides an amount of common sense to offset Ben's impulsiveness and lack of subtlety.

Rook's encyclopedic knowledge of certain Earth trivia has proven to be useful at times.

Rook can jump several stories high. Rook has also been shown to be very nimble and has impressive acrobatic skills.

Rook can understand Sotoraggian language.

In Collect This, Rook shows very impressive soccer skills, having learned the game at the Plumber Academy.

In Charmed, I'm Sure, Rook was able to use magic, as seen at the end when though he had a slight bit of trouble pronouncing the first word, Rook was able to cast a spell from Gwen's Spellbook to teleport Charmcaster to Ledgerdomain, along with using several magical items given to him by Gwen, one of which was accompanied by another spell. However, this was strictly because he was in such close proximity of the Alpha Rune that his spells were able to form.

Proto-Tool
Rook uses the Proto-Tool to help him in battle. He is adapted to using the Proto-Tool as a sword, bow, grappling hook, blaster, and various other things.

Rook has been shown to be an incredible marksman with the Proto-Tool many times. Such as in A Jolt From The Past, he was able to shoot Fistrick's tank from far away on a crane.

Proto-Tech Armor
Rook wears Proto-Tech Armor, which is strong enough to protect Rook from a major explosive shock wave.

Proto-TRUK
Rook uses the Proto-TRUK as his primary vehicle.

Gwen's Spellbook
Rook used Gwen's Spellbook in Charmed, I'm Sure to cast a spell, teleporting Charmcaster to Ledgerdomain. He mentioned earlier in the episode that Gwen suggested that he carry some magical supplies with him in case of emergency.

It is unknown if Gwen was just lending Rook her Book of Spells or if she actually gave it to him, as she wasn't seen handing it to him on-screen.

Weaknesses
As shown in Hot Stretch, Rook can't handle high temperatures for long periods of time, due to having fur.

As shown in OTTO Motives, Rook does not like beam scans as the Zebosans condense on his fur, making him itch.

Rook is a by-the-book Plumber and at times can be too rigid. As a result, he can sometimes be at a disadvantage when facing against an unpredictable foe and needs to 'think-outside-of-the-box.'

Due to being relatively new to Earth customs and culture, Rook is sometimes confused with expressions and Ben's unorthodox style of handling certain situations. At times, he takes certain expressions literally.

Rook is also somewhat naive and too-trusting, which can lead to misunderstandings or awkward situations.

 * Rook is similar to Starfire on Teen Titans. Both lived on another planet and now inhabit Earth.
