Power of the verse
Although it started out relatively modestly powerful, from the Tenrou arc onward, Fairy Tail has become a decently powerful verse. Low to Mid tiers from the verse consist of strong mages that ranges from Multi-City Block level to likely Large Town level in terms of Attack Potency. Mid-High tiers consist of characters that ranges from Small City level to City level+. Top tiers consist of characters that possess Mountain to Island busting power. Some of the strongest characters in the series such as Acnologia and Igneel are at minimum capable of at least Large Island level destruction, with countrywide destruction statements. The verse also has access to a large country busting orbital weapon called Etherion. In terms of speed, the verse is decently fast, reaching Massively Hypersonic+ speeds very early in the series.
Being a verse involving magic, Fairy Tail has a decent amount of hax abilities such as letter based magic which forces a target to comply with certain rules, death magic capable of instantly life-wiping entire cities, Time Manipulation, Soul Manipulation, Gravity Manipulation, Spatial Manipulation, Mass Manipulation, spells which can re-arrange the topography of a country, etc. There are also several abilities which ignore conventional durability such as the ability to inflict others with diseases, Sensory Manipulation, Energy Draining, purifying abilities such as Fairy Law and Fairy Glitter, spells which can erase a target's existence, etc.
