D's. Dabbabah can reach only 1/4 the squares on  boards sizes n x m, where n and m even integers >2. Dame is Queen in more than three languages. Darter is better tag for Falcon than uncomplimentary lame; saying essentially nothing, lame is not descriptive enough, or at all, for multiple paths unspecified. Darter tells not the whole story either, but Falcon can better be called three-path darter, or with some redundancy now, three-path-minimal-distance darter of fixed length. Darter is the far older, established term, and we should eliminate lame that Betza began promulgating after 2000. Jeliss' first example is Alfil Darter, that from e1 cannot go to g3 if f2 occupied. Also, the Knights Mao and Moa that if either e2 or f2 occupied, one or the other cannot get to f3. Betza plays with many like these in an article. Directed pieces would include Falcon and Hunter of Falcon-Hunter (Karl Schultz 1943) the example of Jeliss, Centennial Chess(1997) Spearman, Outback Chess (2003) Platypus.
