Remember the episode where Darkwing Duck ACTUALLY DIES?
...I didn't either. D:
He quite literally goes to hell, then to heaven, then back to earth, eluding the Grim Reaper and trying to rescue his family from the villain that caused his death.
He comes out alive in the end due to a cheap plot twist (SPOILER: dream), but seriously.
Darkwing died.
Think of it like a Doomed Offshoot Timeline from DW's Alpha Timeline, only you don't know that until the end...
For reference, the episode is called "Dead Duck". :[
