Joltik

As the smallest Pokemon in existence, Joltik is often overlooked in favor of bigger, tougher-looking choices such as Magnemite, Chinchou, and Larvesta. As a matter of fact, Joltik is sometimes outclassed by them as an offensive threat, as it doesn't have the same offensive presence or durability. Although, Joltik does have three key redeeming qualities: its typing, movepool, and awesome cuteness. Bug / Electric typing is a blessing in the current metagame. Like Magnemite, Joltik can threaten Water- and Flying-type opponents. However, unlike Magnemite, it sports a valuable resistance to Fighting-type moves. Joltik can also single-handedly defeat almost all Grass-type threats in the tier, such as Foongus and Shroomish—Pokemon that Chinchou struggles with. Larvesta, meanwhile, can only dream of having the Speed and movepool Joltik does.

However, Joltik still struggles to find a place in many teams, as it's not powerful enough to sweep teams on its own and its near-useless abilities give it a difficult time shining. While it doesn't have a crippling quadruple weakness to Stealth Rock like Larvesta, it still should have a Rapid Spin user as a teammate, as its frailness and reliance on offensive items won't let it last long enough. Joltik's ability to hit almost all of the tier neutrally gives it an incredibly useful niche on hyper offensive teams. All in all, with Joltik's attractive qualities, it shouldn't be treated as just a cute bug.
