In the episode "The Comet Cometh", the episode showed that before Duck became a Loonatic, he was a pool boy who was angry at the fact most of his day consist of getting dirty diapers out of the pool.
In "A Creep in the Deep", Duck developed a new way to use his powers. Dubbing the power "Aqua Dense", Duck used it single handedly to propel a boat out of a whirlpool and reverse the flow of another whirlpool with help from Lexi Bunny, showing a worth skill and capacitance, even if he's not a leader.
In “Cape Duck”, when one of Tech's weapons goes haywire causing Duck to take out Sagittarius Stomper, he vows to revenge on Duck. The citizens consider Duck as the one who did it which make the others jealous. Meanwhile, Dr. Dare is released from his statue prison after being hit by Tech's invention and steals the Shield of Perseus. When Tech is finally given credit, he, along with Duck, are made targets by the Stomper, who is somehow able to drop heavy objects on them while still in jail. It is learned by Ace that the Stomper’s mom wears a bionic suit of her son and she impersonates him when he goes to jail. It is also assumed that she breaks him out of jail or vice versa. The two are then both sent to the Acmetropolis Prison.
In "In the Pinkster", we find that Duck is revealed as the second person to personally know a villain as his buddy Pinkster turned out to be a villain much to his horror. Pinkster was one person whom Duck could be considered having a "brotherly love" for as he begged Ace to let him join. Scolded the news reporter for calling Pinkster a helping failure and when it was the night before the Curium when speaking to Ace and the rest he admitted that despite Pinkster's clumsiness maybe there was something he could do that they hadn't thought of. It was revealed in this episode that Duck grew up in an orphanage with his best friend Pinkster and was adopted by a human couple after a coin toss. It's also revealed that Duck was adopted first because of his lucky two headed coin.
Duck longs to one day lead the Loonatics, though he does seem to tolerate Ace's leadership. Before gaining his powers, Duck worked as a swimming pool cleaner, and true to form, he dreamed of becoming a lifeguard.
Duck is a descendant of Daffy Duck (who is also Duck Dodgers when Daffy is frozen in a block of ice), and possibly Melissa Duck or Tina Russo from The Looney Tunes Show. His voice sounds similar to Daffy, but with only a mild lisp instead of the heavy one his ancestor had.
He is usually shown up by other characters or angering them with his antics. He is very boastful and has a habit of attempting to re-invent himself (such as requesting name changes for himself, or attempting to add a cape to his uniform). He can also be extremely opportunistic, once trying to be Slam Tasmanian's wrestling manager simply for profit, then haggling with Slam over how much each of them should get (with preference that Duck receive 90% and Slam 10%). Of all the characters, he seems to be used most often as comic relief, despite or perhaps due to his arrogant personality. This appears to be mostly bluster, as in truly dire circumstances he sometimes lets a more heroic personality show through.
Though he posses a lot of Daffy Duck's traits, Like Plucky Duck of Tiny Toons, Duck has more of a grasp of Right and wrong and rarely employs the same sneaky tactics as Daffy Does to obtain fame and glory.
Danger Duck, even though he doesn't prove it sometimes, is one of the strongest members of the Loonatics, since his powers evolve with time. He also possesses the most destructive potential out of the entire team since his "eggs" are unpredictable. He is sometimes hinted to be somewhat of a co-leader of the group since he from time to time gives orders that even Ace and Lexi will follow without question. Overtime, he also becomes very close to his comrades, especially to Lexi whom he sometimes calls "sister" and Ace who occasionally sees Duck as a brother-figure.
Duck one day hopes to become the leader of the Loonatics. Because of that he sometimes tries to take over the teams missions and prove that he's leadership material. While him and Ace always don't see eye to eye Duck does have good ideas; the team has been known to have Duck lead them on more than one occasion. Although Ace and Duck don't always agree, the two occasionally see each other as brother-figures.
As said above Duck has become close to Lexi. She is also shown to become close to Duck overtime, as she comes to expose her soft side, due to the fact that they save each other multiple times and also because they team up more often than any other Loonatics.
Tech E. CoyoteEdit
Duck is known to criticize Tech's inventions much to the displeasure of Tech. In "The Cloak of Black Velvet", the two made a bet that if Duck went a week without technology, Tech would pay for costume he had been been trying to order. However, Duck loses the bet when he used his phone to break Tech out of Black Velvet's mind control. When Duck and Tech were being chased by the Stomper in the sewers and Tech was captured, Duck unselfishly rushed in to save Tech. Although Duck messes with Tech a lot, he shows that he cares for him and respects his inventions.
Rev and Duck worked together when trying to find out what caused the four villains from previous episodes (Massive, Weathervane, Mastermind and Sypher) to disappear in the episode, "Acmegeddon". Other than that, Duck occasionally criticizes Rev although they do get along.
In the show, they generally get along although Duck acts like a parental or older brother figure to Slam; occasionally reprimanding him on his table and eating manners. In "I am Slamacus", he declares himself as Slam's manager to Pierre Le Pew only so he could get a cut in the amount of money Slam wins.
Pinkster Pig Edit
Duck grew up in an orphanage with his best friend Pinkster and was adopted by a human couple after a coin toss. However, it's discovered that he cheated by using his lucky two-headed coin to win. He reveals this as his fourth darkest secret, which caused him two nightmares. To make it up to Pinkster, after hearing about his misfortune afterwards, he begs Ace to let him help them capture Stoney and Bugsy, which the leader reluctantly allows. Despite how clumsy Pinkster was, which lead to failure each time, Duck continues to support him. He is heavily shocked though when he learns that Pinkster was working with Stoney and Bugsy the entire time, acting as a spy. Even so, Duck believed that there was still some good in him.
- Power Orb Randomizer - Tosses powerful flaming spheres of energy (often referred to as "eggs"). Results of impact appear to randomize, common results being concussive explosions and tar. On some occasions his eggs generate random substances such as orange juice and boulders. Though the results are randomized, Duck seems to be able to control the results to a small degree at times.
- Aqua Dense - When throwing his "eggs" near or in water, Duck instead fires powerful blasts of aquatic energy. Duck has also used this ability to control the flow and direction of water, endowing him with hydrokinesis.
- Quantum Quack - The ability to teleport (or "quack" as Duck himself calls it) short distances through (and sometimes into) solid objects. There is a slight delay between his dissapearance and reappearance after he quacks.
