Hi Enchilada,
My favourite L Toon characters are Marvin, Yosimite Sam, Foghorn Leghorn and that Tassie Devil. But the last two, I believe never were in any outer space or scifi adventures.
Here's one that was around for a while but not well known. Not a very good one.

Invasion of the Bunny Snatchers.
It follows something like the old sci fi movie.
Cheers Marty
