Quaquaval is a Water & Fighting type, is the final evolution of the Water starter Quaxly, and has a pretty good design. Just barely edges out Meowscarada and Skeledirge as my favorite design for the paldea starter final evolutions, but like Meowscarada, I'm not a huge crazy fan on Quaquaval's shiny. Now, when it comes to battling, Quaquaval is probably the worst of the starter final evos, but it's still pretty good, I mean it came in clutch a few times during my violet playthrough on my team. Quaquaval still has okay enough stats, decent enough abilities and a decent enough movepool. In general, I absolutely love Quaquaval, and would happily use it again in future on a playthrough team, but I absolutely love the other six pokemon left way too much to rank them lower than this starter.
