4-DAC

4-DAC is a supporting protagonist in Jonny Quest vs. The Cyber Insects. It is an A.I. robot assistant that created by Dr.Benton Quest. It has a masculine sounding voice.
==Biography==
At Quest HQ, Jonny finds his copy port missing, 4-DAC comes and informs him that he has it, Jonny reprimands him for sneaking up on him like that. 4-DAC remarks he should consider shutting down in order to program footstep sounds into himself. When Jonny asks for it, 4-DAC asks for the password per security measures. Jonny tells him the password “Amber”.
At the lab, 4-DAC reports to Benton that all the climatic data has been downloaded into a single data file. Dr. Quest proceeds to put it into the holographic visualization program. Jonny offers to help out with the three dimensional graphic modes, but his father refuses as he says that he, Race, and 4-DAC can handle it. Just then, Jessie rides in with her father Race reprimanding her for riding her hoverboard in doors. When Jessie asks about the Orinoken Ceremony. Jonny says that when he cannot tell her what happens in a man’s sacred circle because she is a girl.
However, she correctly guesses he blew it as he lept before he looked. Once Benton aligned all visual data and sequenced all graphic nodes, he put the holographic composite online. When the holographic image of earth got brought up, there were many thick clouds. With Benton noting how everything is off kilter with spiral scroll lines across Europe, East-west cloud systems covering North America and nimbus towers above most of Africa. Race also notices a series of high storm systems covering the world.
Jessie believes something hot was causing a strong convection current in the principle of jet streams. Jonny suggests some volcano or forest fire was doing this, but was rebuked by Dr. Quest for being quick to criticize as he must explain any reasonable theory such as Jessie’s. Benton orders 4-DAC to alter the program to isolate the unnatural variations in temperature.
Just then, they find that there are hot spots over the North Pole and the ice cap is melting faster than usual and destabilizing the atmospheric jetstream and creating high pressure storm systems across the planet. Benton then thanks Jessie for the suggestion.
When Hadji asks what was causing these hot spots and how to stop them, Benton says he does not know, but his friends on onboard Quest Station could help find the cause. When he contacts them, Dr. Eve Belage answers and wishes she could help, but the spectrum analysis computer was not working correctly and their entire sensor stack is offline, making it impossible to track down the hot spots affecting the North Pole. 
4-DAC proposes a personal transport for a replacement computer to Quest Station to restore the sensor capabilities there so they can complete their investigation. Something Eve believes might work. Once they get weather permits, Benton and 4-DAC will ride in Quest Shuttle-1 so they can bring the sensors back online in order to track down the cause of the weather situation.
Just then, a strange ship full of insects flies down to earth followed up with a scattering of birds in the area, which strikes Jessie’s curiosity and Hadji notices they have been heading west all day. Jessie also points out that there are too many species flocking together and something scared them in the river. Jonny suggests they ride the hover sleds in order to look upriver. But Jessie explains that her father did not say they could run off like that for investigations.
They all then fly off to investigate where they witness rain and lightning where Jonny gets into an argument with Jessie about him failing his test before they fly out of the storm. 
After the kids escape a group of insects (Including several massive ones), 4-DAC reports that the swarm was heading towards Quest HQ and has them observe, before Jonny comes, Benton tells him that the way he ran off this morning made him worry. He asks his son why he takes on such foolish risks.
Jonny wanted to do his share and become a full member of the Quest Team. Benton explains that being part of a team means to work with others and not around them as he needs to learn patience. 4-DAC explains to everyone that the giant insects they have encountered were controlling the swarm of insects with a high frequency signal of unknown magnitude and duration. When Race asks about a way to jam the signal, 4-DAC says that such a task would be possible after getting enough time which Benton says it is not something they have and must rocket off to Quest Station soon. Jonny finds a recording of Atacama’s music to control fireflies on his computer and Hadji realizes they can modify it to control the ants. Benton suggests to 4-DAC that he creates a signal to redirect the swarm away, which 4-DAC complies with almost immediately.
Dr. Quest thanks Jonny for the suggestion to deal with the swarm, but reminds him that it still takes a good team to make a good plan work. In the middle of the rocket preparing to launch, the swarm of insects threaten to jeopardize the launch by entering vital components. But Jonny broadcast the signal to drive the insects away immediately.
Watching the rocket launch, 425 apologizes to Zin for his failure, but his master shows how unforgiving he is by having several of his hymenthoids drag him off to be executed for his failure as he cannot allow Benton to find his stealth satellite and replaces him with 426, warning her not to fail him in killing Dr. Quest and his team.
After Quest Shuttle-1 docks, Eve welcomes Quest and 4-DAC to the station as they replace the computer to fix the sensor. Eve explains to 4-DAC that the flowers he was looking at never bloomed for three million years and she was recreating extinct plants and animals and had the assistance of Mylana through DNA samples.
Just then, Benton contacts Race and he and his teammates were hunting down one of the humanoid insects who attacked them when the weather has taken a turn for the worse. Benton tells him to do his best as the bugs and the weather might be connected. Jonny reassures his father that the bugs cannot outrun their flying segmented weasel vehicles.
Dr. Quest reminds Jonny about that he must have patience and teamwork and he must not do it on his own as he must play it safe and smart. Checking on a valley north of them, they were pursued by the formicoids who witnessed them head there.
After completing the installation of the spectrum analysis computer, 4-DAC re-activates the sensor stat for Quest Station in hopes of solving the problem with the weather.
Eve tells Benton that while 4-DAC is running the analysis, they will establish a satellite link from I-One Central Command so they can access all their data. As 4-DAC initiates a spectrographic sanc on the computer for earth’s problems, the computer explains that the Refracted sunlight has been optically enhanced and directed towards the earth’s surface. 4-DAC asks why Quest Station’s radar could not find the source of the refraction.
The computer explains the source might be protected by a radar shield or another form of stealth technology. 4-DAC tries to break the shield and tries to get a detailed sensor probe of the objects. Just then, 427 finds that Quest Station is probing their satellites, 426 calls this impossible as the satellites were shielded by parabolic reflectors that the station should not be able to track. 427still says that they are doing it. 426 orders for 427 to use the Trojan Horse virus to deal with the issue despite his protests that it is untested. This leads to 4-DAC being infected by it.
When Dr. Zin finds out about the infection of 4-DAC, he announces that he will have work for him to do.
Back on earth, Race Bannon and company come across a cabin and realise it is occupied. However, a tank-like cyber insect bursts out of it and fires at Race’s vehicle, forcing him and Hadji to retreat. Jonny and Jessie however destroy it with their Weasel, saving the two.
But another formicoid begins to shoot at them. Hadji retaliates by making coconuts fall on it while Race shoots it down. At Quest Station, Commander Harris explains that the situation was deteriorating rapidly as food and water are dwindling while civil order is on the verge of collapse.
He orders for answers to be found fast with Benton telling him that they should have something shortly. When Eve checks on 4-DAC, he claims he must excuse himself from active duty to replenish his power pack. Eve is not happy as the work he is doing was extremely important. 4-DAC leaves, claiming he’d be back in 3.9 minutes.
At the mainframe, the infected 4-DAC announces he has taken control of Quest Station’s computer and its defensive systems. Dr. Zin orders for all of the files to be transferred to his mainframe immediately and then trigger the auto destruct sequence to destroy Quest Station.
But the destruction was stopped due to a lab dedicated to studying the infamous Pselliopus Cinctus Anticus which led to Dr. Zin ordering 4-DAC to head there. Back on earth, Jessie examines the appendage recovered from the formicoid and it was organic but contains an anti-mechanical power pack of some sort.
Jonny asks her to say something important like where the big bugs came from. Jessie considers them to be from another planet or solar system. Jonny believes she read too many comics. Race asks Jonny to cool down as they are on the same team.
Jessie laments 4-DAC’s absence as he could do a first class analysis on the limb. Jonny tries to contact the robot, but does not succeed as it seems 4-dAC is offline. After 4-DAC arrives at the lab, Dr. Zin commences the virtual reality interlock while 4-DAC enters the lab and procures a specimen.
Once this was done, Dr. Zin ordered the capture of the entire station.
Back with Benton, he finds it impossible that 4-DAC was offline with Eve mentioning that the robot was replenishing his power packs. Jonny points out that 4-DAC should not have another replenishment as he did before lift off and should have taken longer for him to recharge.
Just then, the transmission gets jammed as the satellite loses control and gets dragged towards Zin’s asteroid fortress. Dr. Quest orders the activation of the emergency lights, but the communications are down and the computer is offline and they cannot access the sensor stack.
They initially had no idea where they were or what was happening. After Eve suggests they look out a window, they find that they are inside Dr. Zin’s asteroid fortress.
426 announces that the stabilizers have been secured and the docking procedures have been complete. Dr. Zin then orders the air pressure to be equalized immediately, anticipating his talk with Dr. Quest. The Cyber Insects head towards the captive Quest Station to equalize the pressure while Zin greets Benton.
As a result of lost contact, Race resolves to go with his companions into space on Quest Shuttle 2 in order to locate Quest Station.
When they were armed with laser guns, Dr. Quest and company prepare to fight back against the Cyber Insects. However, while they manage to shoot several dead, the infected 4-DAC intervenes and threatens Benton with death if he does not surrender to Dr. Zin. Dr. Quest and company comply and drop their weapons. Most of the staff get taken to the cargo bay by the insects on Zin’s orders while Benton and Eve are to be taken with him through the fortress as he has plans for them.
At Quest HQ, Race was preparing to launch Quest Shuttle 2 so he and Quest Team could head investigate what happened to Quest Station. Harris contacts him to notify him of the winds dying down and he must hurry as he still had the launch widow. Just then, Harris reports there have been floods and tornadoes taking the world apart at the seams and they have no idea why this is happening and they were desperate for answers and Dr. Quest was the only person who knew what they were.
After Quest Shuttle 2 launches, Dr. Zin is showing Eve and Benton the interior of his fortress and introduces several of the species of Cyber Insects he created in order to conquer the earth, his planttinoids were created from the ordinary cockroach and proven their obedience and dependance, the formicoids are fearless, capable, and devoted warriors unmatched by his hymenthoids. Eve calls this a waste and asks why he does not put his obvious abilities to more constructive use.
Dr. Zin explains that he has the lepidoptoids digest useless and raw material and recycle it into hydrated ethylene to be fermented and distilled into ethyl alcohol carbohydrate called Ethanol, which he intends to offer as a renewable renewable non-polluting fuel to the people of Earth once he conquers them. While 4-DAC does find this sound on the surface, the logic was actually quite specious as processing and storing large quantities of explosive ethanol is highly dangerous and should store it in closed containers.
Dr. Zin zaps 4-DAC with a taser and has the robot thrown from the bridge by two of his formicoids into the ethylene out of annoyance. Traveling to where Quest Station was, Race notes that there would be 12,000 tons of debris if Quest Station did explode. Jessie wonders how an entire space station disappeared, with Hadji saying he is not capable of this magic.
Dr. Zin shows Eve and Benton what he plans to do with the DNA of the Pselliopus Cinctus Anticus, a prehistoric assassin bug Eve researched. He plans to turn some larvae into killing machines called assassinoids and, once his satellite brings Earth to his knees, they will lead his insect army against every major city in the world in order to seize complete and utter control.
Dr. Quest calls him mad while 426 reports that Quest Shuttle 2 is coming their way. Zin orders the targeting program to be activated. Dr, Quest tries to reason with Zin as he has no reason to destroy the shuttle as the asteroid was invisible to them, which 427 agreed with.
426 also points out that the ion cannon will compromise their position before they can invade it, Dr. Zin refutes these concerns as he was unwilling to lose the chance to rid himself of Race Bannon and his companions. After having hymenthoids restrain Eve and Benton, he has 426 made a test subject for the toxo-rhynoid project. He then has the formicoids drop her down a trap door to the mosquitoids.
He now places 427 in charge. Back on Quest Shuttle 2, Jonny objects to his group returning to earth per Harris’s order as the worldwide weather conditions are deteriorating rapidly and almost every airfield on the planet got sucked in. He warns that staying in place might strand them. Race explains that Quest Station did not explode or fly off on its own and it should be around the area they are in.
Commander warns that they have an hour before the window closes on them. Hadji suggests to Jonny that he uses his copy port system in order to talk to 4-DAC, something Race finds worth a try as they could find Quest Station. Jonny types in Amber to find that he was infected by the trojan virus.
Just then one of the larvae sheds its skin while Eve points out that the assassin is one of the most dangerous insects alive today and Benton points out their ancestor was ten times as deadly. Eve complains that creating a giant version of such a creature is insane. Dr. Zin then asks why she was cloning them. She explains she was cloning them for medical research to help people. He then has formicoids take the two away.
After Jessie finds an antidote program, Jonny uploads the program into 4-DAC and returns him to his normal programming. 4-DAC explains that Dr. Zin was behind everything that has happened. Just then, the insects seal up Eve and Benton in a holding cell where Eve laments their situation while Benton reminds her that she grew up in a small village in the Orinoco River Delta and put herself through school where she became a great scientist.
He reassures her that the Quest Team is looking for them, giving her some hope. Just then, Zin muses that he will have hundreds of assassinoids lead his attack on earth, and orders the Cyber Insects to prepare the invasion force. 
Race Bannon reports to Harris that Zin trapped Quest Station inside his asteroid base and was using stealth satellites to control the world’s weather. They were homing in on 4-DAC’s signal.
Just then 4-DAC frees the captive Benton and Eve then proceeds to escape with the two.
Before they reach the location of the base, 427 reports that the shuttle is approaching their position again and is ordered to send out the defensive army where they confront Quest Team and try to shoot their shuttle down. Once power is lost, the shuttle begins to fall back to Earth while Race loses consciousness. Hadji tells Jessie to tend to the shuttle while he and Jonny tend to her father. Jonny then manages to help her get the shuttle back on track.
When Benton and Eve come close to getting in Quest Station, they find that there are too many insects and they might spot them. 4-DAC proceeds to scan the computer and find Zin’s personal escape capsule two levels above them and could provide an avenue of escape. He then leads them to where they were.
Around this time, two of Zin’s drones throw him into a capsule to have him frozen to death and shattered to pieces for letting Dr. Quest and Eve escape, despite not being in charge of watching them. Zin then has the Cyber Insects who threw him in the capsule replace the deceased 427 and find the escapees.
Just then, the kids try to help Race regain consciousness. Just then, he recovers in front of Bandit and the kids. Commander Harris also examined the tapes of their encounters with Zin’s interceptors where he learned they have had some form of cloaking capability, which makes it a perfect cover for an ambush. Jessie also has an idea at what happened to Benton and Quest Station. Commander Harris confirms this as they have been cloaked in the same field.
Jessie reminds her teammates that Jonny traced 4-DAC’s signal in his copy port. A frustrated Jonny asks his friends to keep him out of the search for Zin’s base as he could only make things worse. 
Hadji and Jessie confront Jonny where he states he does not know how to be a member of Quest Team and too much of a kid. Jessie tells him he was still a kid who helped her fly the shuttle or stopped a swarm of insects back on earth. Hadji also reminds him he was a kid who helped 4-DAC and locate Zin’s asteroid. Jessie also asks him if he was the only person to make a mistake and being an adult is about learning from his mistakes. Race then tells them they have work to do.
Back on Zin’s base, Dr. Quest asks 4-DAC how much farther it is from Zin’s escape pod, the robot explains that it is 32 meters down the duct and past two guards. 4-DAC runs off to buy them time. After several hits, 4-DAC goes down. When they try to turn on Zin’s escape pod, they are stopped by the Cyber Insects.
When he, Jonny, and Jessie retreat from an Assassinoid, Bandit runs off to where they find 4-DAC buried under soil, and proceeds to recover his a.i. and secure it in his copy port
4-DAC in Jonny’s copy port provided good and bad news, they are near the chamber where the captives are being held and the bad news is that Zin sped up the computerized mind melt. There is less than an hour before they cease to exist independently.
Just then Jonny is confronted by Zin when he enters the holding place of his hostages and the assassinoid melts a segment of their weasel. Race also finds out the assassinoid can regenerate lost limbs, including its head. Just then, the bug gets caught in liquid nitrogen and smashed to pieces.
Bandit then takes a frozen piece of the insect while the rest of them regenerate into more assassinoids.
Jonny decides they must save Quest Station first before saving his father and Eve.
Just then they find the assassinoid body part growing into a larva. 4-DAC’s analysis of the Assassinoid larva they have was in the process of regenerating and will metamorphosize back into a fully formed adult assassinoid and the only way to destroy one is to either use a thermonuclear explosion or freeze them. Mylana decides to have the larva taken to the cryogenic lab on Quest Station to be frozen in liquid nitrogen.
Jessie also tells Jonny that he should now be an adult as he learned from his mistakes. Hadji also tells him that this is a good time to keep his head down. Race then tells Jonny it is time to go. They then find themselves in conflict with the Cyber Insects.
Jonny drops his copy port before he could call the weasels. Just then, Bandit runs from Hadji and causes barrels to roll into the insects, enabling Jonny to recover his copy port. Jonny and Race run to the command room where they upload the virus into the mainframe with 4-DAC’s help.
Jonny Quest then has the doors shut on most of the attacking insects then opens the door so that Quest Station can escape, leading to the insects present in the docking bay getting sucked into space.
Back on earth, Chief Atacama holds a ceremony as Jonny and Hadji have proved themselves to be in the sacred circle and adulthood. He also says their companions may step forward and witness this as they touch the sapphire. Jonny also asks Jessie to touch the sapphire as well. Bandit and 4-DAC, in a new body, also watch as they do so.
