Huntail or Gorebyss. Both learn Shell Smash and baton Pass and can use a White Herb to restore defences and can be good as they are bulky.
-Surf/Razor Shell (Huntail or Gorebyss)
-Any move of your choice
Again those are the only options.
No Pokemon that are Water-type and can learn a special boosting move and baton pass unless the ones listed above.
Drifblim, Blaziken line, Scizor line, Furret line.
-Any move (preferbly attacking)
-Any offensive move (Taunt)
Unfortunately there are no water types with Focus Energy and Baton Pass.
Hope I helped!
-It's a secret!
