It's usually about the final form (3rd) evolution of a Pokemon family because of the stat boost, obviously, but every now & then I come across a cool middle-evolution that looks even cooler than their 3rd form. For me, Nuzleaf was always badass looking compared to the ugly & homeless-looking Shiftry. Other cools ones are Wartortle, Haunter, and Dragonair. Whether it's design-wise/aesthetic or some other reason, which ones are your favorite 2nd evolution?
