Differences, and added stuff from the old cartoon
As show by the Ducktales reboot, Drake Mallard was a big fan of the Show Darkwing Duck, and strived to be like him, and his chance came after a failed movie pitch. Later on, he left Duckburg, leaving Launchpad McQuack behind.

They would soon reunite after fighting Taurus Bulba, and rescuing his now Crime Fighting partner Gosalyn.

A few years later in his career, F.O.W.L. Sent 2 all out attacks on Darkwing Duck. First with a mission with a stolen Painting, which actually had plans for a robot doppelganger of the Masked Mallard, which Darkwing destroyed.

A few weeks Later, F.O.W.L. recruited a few more of Darkwing's rouge gallery, and when they were defeated, Darkwing faced Steelbeak on F.O.W.L.'s flying fortress and defeated him, ending F.O.W.L.'s reign of terror for a while, but his adventure wasn't done yet, as Negaduck appeared, and Abducted Morgana, Darkwing's girlfriend, and Challenged Darkwing to a fight, which Darkwing won.

But a few days later, Negaduck found out Darkwing's secret identity, and broke into his house, and was only defeated thanks to Taurus Bulba's crime bots.

Thinking that he wasn't good enough to be a hero, Drake retired from being a hero, and cut ties with everyone but Gosalyn for a year. This is where the differences end.

Beginning life in Sonic Ultimate Timeline
When Dr. Eggman was experimenting with different dimensions, Darkwing's Universe was one of the one's he decided to invade along with Mega man's world, and teamed up with the villains in the Universe as well, Darkwing then teamed up with Sonic, and later Mega man, and Protoman to stop Eggman's newly formed Neo Eggman Empire, but despite defeating the villains, their worlds combined, making his city, and other things from his world appear on Mobius.

A few months later, The Neo Eggman Empire tried again with messing with the Multiverse, causing The newly formed Fate Changers to free the Multiverse once again from the villains. And with the help of Discsonic, they squashed the evil Empire and returned home to Sonic Ultimate Timeline.

Later life in SUT
Darkwing Duck, as a major part in the Fate Changers, has gone on almost all of their adventures when he wasn't taking care of Gosalyn. One of his most famous adventures is when Dr. Eggman distracted Darkwing and Sonic while Steelbeak nuked the city of St Canard. But luckily, He, Sonic, and a few others stopped the fiends, and restored St Canard

Darkwing Duck also helped when Dr. Eggman merged all the Dimensions of the Multiverse into one, often fighting enemies and saving people, and fought Negaduck when the Multiverse started collapsing due to Eggman's recklessness.

Currently, he is aiding his friends in FT (Forbidden Timeline Not my Universe) to stop an unknown enemy threatening the Multiverse (It can never catch a break, can it?)
