Leekdux is Leekduck Ducktor's X-antibody. He is a genius like Leekduck but is also dangerously insane. He is under the delusion that he is Leekduck and there is no Leekdux. He also has no grip on the outer world. Reality is different in his mind and he lives in one big hallucination. He can, however, just about barely make out other living things and can use his wand to make his victims as mad as he is. Leekdux cannot fly and has no feet and no tail since he leviatates and has no need for them.
