It has been rumored that when TaleSpin was created, Launchpad was originally meant to star in the role of Baloo.

Tad Stones commented on the Old Haunt forum:

I forget whether this was in this thread or another, Talespin was never to be Launchpad’s show. It evolved from a show called “B-players” that concerned all the co-stars of Disney features trying to get acting jobs or odd jobs to finance their careers. Sort of a Roger Rabbit conceit. Launchpad wouldn’t really fit in a TaleSpin world. I mean, we changed him a lot to fit him into Darkwing’s.

Thank you Tad for clearing that up!
