While the power of the verse can greatly vary, the verse is much more powerful than one would expect; fodder characters in most Fire Emblem games have been known to withstand the Meteor tome, which packs
Town levels of destruction. Except for the GBA characters fodder who should still be
Large Building level due to being able to cast Fimbulvetr and trade blows with enemies on similar power levels.
In Fire Emblem Three Houses, the Low tiers are
Town level due to Meteor. The Mid tiers are
Mountain level+ due to being half as strong as the low-end of the God tiers. The God tiers are
Large Mountain level to
Large Island level due to the Javelins of Light.
There are many large dragons in the games like
Anankos which have been shown destroying large castle towers, and the stronger endgame bosses such as
Fomortiis are commonly seen as threats to casually destroy entire countries.
In the Tellius games, most characters are
Small City level via Rexbolt. The most powerful character in the Tellius timeline,
Ashunera is
Multi-Continent level via flooding the entire world except for one continent; this scales to Ashera and Yune due to the two of them each being half the power of Ashunera. Characters such as
Ike and
Micaiah both have the power of Yune, and thus scale to this rating. While not part of the same timeline, characters from Elibe such as
Roy and
Idunn are also this tier via scaling to the Divine weapons, which were collectively able to cause the Ending Winter, an event that distorted the laws of nature, and heavily altered the climate of the planet.
Fire Emblem Heroes features the most powerful characters in any of the mainline entries, with characters reaching
High Universe level via scaling to
Hel, who becomes stronger with every death in the infinite multiverse. Users of the Tempest,
Azura, and
Freyja reach
Multiverse level+ due to being able to create, destroy, or manipulate infinite worlds. The most powerful entity in Fire Emblem, Alfaðör, supposedly created all of existence, however he has yet to make an appearance.
The spinoff games also feature very powerful characters. In Tokyo Mirage Sessions #FE, characters reach
Solar System level due to being able to affect an entire illusionary world which contains multiple suns within it. Fire Emblem Warriors has Velezark the Chaos Dragon, a being who can bend all time and space, distort the fabric of reality, and consume entire worlds and dimensions.
A typical Fire Emblem character should have
Massively hypersonic combat speed and reactions as many of them can dodge arrows, cloud to ground lightning attacks, and meteors on a regular basis. Also, the swordmaster attack animations in some games show them moving faster than the eye can see and casting several after images. In Three Houses, the god tiers even have
Faster than light showings.
