Donald duck was one major threat to the timeline. The time police inventor creates a device that informs of threats to timelines which says that donald duck was major without explanation.
The reason why is lot of reasons. Related to scrooge mcduck and very close to scrooge mcduck.
Has or will time travel to ether the past or the future thanks to magic or technology.
Important person in various life's that will make the future better or worse by his actions on their lives like Pete and goofy.
So some self righteous timepolice members decide to take care of donald duck by preventing him from being a threat which goes wrong and other timepolice go in to prevent the first group.
making a paradox labelled officially by timepolice as duck paradox and a group having to monitor donald duck 24/7 to prevent any problems relating to time.
