Low-quality content needing perfunctory effort to be made, created as an appetizer, but not satiating the metaphorical hunger of the fans. It usually comes in bursts, or is cyclical.
For the anime, filler is content that doesn't advance the plot.
The Pokémon designs of the Fifth Generation are the closest thing to filler in Pokémon that can be found.
The Pokémon depicted in this picture here is "tantamount to my Mother's steely cogs."
