The final fight showcases Beak's greatest flaws: his laziness and overdependence on copying off others. He spends the first half of the fight just stealing the other's technology and augmenting them into his armor. After Gandra tricks him into relinquishing them, he becomes vulnerable and his final digital form is just his very large head. While Beaks is genuinely intelligent and can be a decent inventor, his lack of work ethic means that he can never truly prosper and his entire way of life was doomed to fail.
Not to mention that Beaks didn't actually use any of the tech in the fight successfully. Beside the extending arms, Beaks only uses the copy ray with anything resembling success. Despite the fact that everyone else was able to stagger him individually with the tech they created, he couldn't do anything impressive with them or even tried to. An arsenal of new weapons at his finger tips, and Beaks can't even put in the effort to use it well.
At the end of the episode, after suggesting that she quit F.O.W.L. and take Gizmo Cloud off its servers, Gandra logs off and is about to leave her office, only to find Bradford waiting for her to confront her about her decision. How could he have possibly known about her plan so quickly? Well, Bradford is the head of F.O.W.L. after all; it's not much of a stretch that he knew about Gizmo Cloud the entire time and was watching everything Gandra and Fenton did, despite their precautions.
Also, it didn't seem to occur to Gandra to use a secure channel and server for her communications with Fenton so that Bradford wouldn't find out. Even if she did that, her external communications would've registered on F.O.W.L.'s servers as unauthorized, and the director would've still picked it up and traced it back to Gandra's computer.
Given his size and shape, Li'l Bulb is physically incapable of wearing VR goggles, which would seemingly bar him from entering the Gizmo Cloud. However, given he's a machine with an A.I., he could still enter the system by literally plugging himself in.
The Eggheads Bradford orders to apprehend Gandra, a trained F.O.W.L. agent, do so in a matter of seconds. Typically, most Eggheads aren't known to be bright or exceptionally competent in combat. Not to mention how they were embarrassingly defeated by Launchpad and Dewey, who are untrained civilians, and even one muscular Egghead who was not made dumb by Black Heron's intelligence ray could not quickly react against Smart!Launchpad who karate chopped him. It is evident that these Eggheads are of a higher calibre than those commonly seen (such as Pepper), and it makes sense that Bradford, being the Director, would have the best ones.
In Escape from the Impossibin, Fenton is among Webby's list of potential traitors. This episode reveals that Fenton and Gandra have been staging confrontations and working together in secret. It's entirely possible Webby noticed this, but drew an incorrect conclusion.
Officer Cabrera brings up Louie's Kids claiming that it's been cited as a charity fraud and Louie is a suspect of interest. Even though it was stated that Louie used the fake charity to trick Uncle Donald into giving him money, the fact that Officer Cabrera is aware of its existence and brought it up so quickly implies that it's known to the general public. So how many people did the evil triplet con out of their money with Louie's Kids? It's also important to consider that he created the fake charity scheme before he moved into the mansion and learned work ethics from Uncle Scrooge.
Bradford has essentially kidnapped Gandra, and he confiscates her phone before she can dial for help or warn Fenton. He can even have F.O.W.L. manipulate her correspondence with Gyro or Fenton and send them on a Wild Goose Chase. How bad is it going to get for both Gandra and Fenton before the Series Finale?
He could lure Gizmoduck into a trap, or blackmail him. Every man has his weakness, and Gandra is Fenton's weakness.
Of course, Gandra will be lucky if that phone explodes in Bradford's hands since it's a Waddle phone.
Now that F.O.W.L. knows about the Gizmocloud, Bradford can essentially use it to control the entire world's infrastructure, access people's medical records, banking and credit card statements, and very much implement mass surveillance should he release it once it's perfected. People who use this system to interact with others practically give out their deepest secrets they don't want to tell the public about, and if F.O.W.L. controls it, there won't be anything they don't know.
You can only imagine what Mark's mother thinks of him now. His company stocks tanking, products exploding and him being unable to come up with something new, it wouldn't be a stretch to say she considers him a disappointment and a deadbeat who can't make something with his life. And who's to say Emma hasn't disowned Mark either?
And to say nothing of Coach Beaks (assuming he's still around), who undoubtedly now thinks of his son as an even bigger loser than he thought.
