10. Lanturn
First up we have Lanturn. Debuting in Generation Two games 'Gold & Silver' this Pokemon offered one of the first ever contradictory type combinations. Lanturn is primarily a Water type Pokemon, but its secondary type is Electric. Since Water type are weak against Electric types, this offers Lanturn a helpful advantage against other Water types. It can naturally learn several of the most powerful moves from both Water and Electric movesets, and can even be taught a few Ice type moves by tutors or TMs to help take down some of those pesky Dragon types. It's dual type also means it is one of few Water types that does not have a weakness to Electric attacks. Unfortunately Lanturn's secondary type does make it susceptible to Ground type moves, but Ground types are also weak against Water types, meaning that if you manage to get a quick enough one you'll be able to neutralise the typically slower Ground type Pokemon before they can capitalise on this. This brings us nicely on to the stats; Lanturn does benefit from the ideal that most Electric types are quick and has a decent speed stat. Unsurprisingly considering its dual types it has higher special attack and special defence stats than the more physical ones; it is an excellent distance battler. Finally, Lanturn has the highest HP stat of any Electric Pokemon, meaning that it is able to sustain far more damage than others typically would. If you're looking to build a team around durability and distance, you'll definitely want to consider Lanturn...
