Yes there are. Tynamo and it's evolution line (Eelektrik and Eelektross) are an Electric type with Levitate, thus having no weaknesses, unless they are under the effects of Gravity, Mold Breaker, or anything else that disrupts the ability.

I think any electric type Pokemon would be okay.
Electric-types only have one weakness and that's Ground-type. Any Pokemon can defeat Electric-types, but using a Ground-type will likely have a super effective, making the Pokemon faint quicker.
Any Pokemon that's effective against an electric and flying type Pokemon.
Here are their pokemon-their weaknesses:Umbreon-Espeon-Flareon- Any water-type pokemonVaporeon- Any electric-type pokemonJolteon- Ground type pokemon, I recomend Geodude's evolutions(Graveler, Golem)
Really, any Pokemon can beat a water Pokemon if its strong enough but the easiest way is to use a grass or electric type that has a same or greater level than the water type.
