ITT post pokemon that have decently strong final evos but they're a pain to use because they evolve too late and their first forms are pretty weak.
Duskull fucking sucks ass to use in gen 3. Shuppet too for that matter. Duskull is slow and weak, and it's defenses do not make up for it's paltry HP. Meanwhile shuppet has decent attacking stats, but, of course, it's a SLOW FRAIL MIXED ATTACKER, so it's paper thin bulk and non existent speed make it a massive pain to use. Which sucks because I love both their designs, as well as their evos.
