You gotta feel sorry for Kingler. In the Indigo league its treated like some beginners luck powerhouse where it clean sweeps 3 Pokemon in a row from the same trainer. Then in a second match it beats a Cloyster.
Following that, Kingler is used in the Whirl Cup in Johto. It beats Misty's Poliwhirl, but unfortunately loses to Psyduck's DEM powers.
After that...that was it. Kingler didn't participate in the Johto league, and it didn't get used in AG at all. And now in DP it looks like it is once again sitting out the league.
My only guess is Ash has far too many water Pokemon now and since Kingler isn't a starter or main team Pokemon, it gets left out. Its also odd that Kingler is Ash's only fully evolved water Pokemon. What a shame.
