I always assumed Darkwing, DuckTales and Talespin were all in the same universe BECAUSE of Launchpad.
DuckTales 2017 threw a wrench in that theory by repeatedly emphasizing that only DW himself actually belonged in universe, but I loved the way the did the origin story so damn much that I didn't care.
Like straight-up, that was one of the best written episodes of anything that I have ever seen.
