Every Pokémon Type, Ranked Weakest To Strongest

When the first games were released in 1996, the type match-up chart looked a lot different than it does nowadays. A few years later, Generation 2 titles introduced the Dark- and immensely useful Steel-type, and nothing was ever the same. Fifteen years passed before a new addition came, with Fairy-types arriving to balance out the seemingly overpowered Dragon-type, which did not have too many effective counters until then. At the moment, eighteen types of Pokémon dominate the universe of the franchise – types that are often adapted when inserted into other game formats.

Some types definitely rank higher than others, especially those with the strongest Pokémon in their ranks or those with the most resistances and immunities to other types. Others are stuck at the bottom, whether because of their frailty or lack of memorable creatures. This is further intensified by the possible type combinations present in the game – and the unused type combinations that may one day be explored. All of them create the perfect balance, though, providing color and variety to the over 1,000 Pokémon species that exist, but one of these is the strongest type in the franchise.

Some Pokémon types really don’t seem to match up with the Pokémon themselves, perhaps at least a couple of these could be corrected in Gen 10.

The Bug-type Pokémon get a bad reputation and they somewhat deserve it. Except for some really noteworthy members that considerably elevate the type's stat average, most of its Pokémon are quite weak. Indeed, Bug has the lowest average stat total of fully evolved Pokémon, with a meager 467, according to data compilation posted on Bulbapedia. It's also the only type that hasn't been assigned to a Legendary Pokémon so far.

There have been Bug-type Mythicals, like Genesect, Bug-type Ultra Beasts, like Buzzwole and Pheromosa, and Bug-type Paradox, like Slither Wing.

Weak to three types in the series and resisted by a whopping seven, Bug-types certainly are not the strongest
