FFT isn't as bad about overpowered characters as Aedis Eclipse, where near the start on all the routes it gives you with minimum effort multiple secret characters with ridiculous stats and equipment that can practically solo the rest of the game by spamming their special attacks (only really struggling with oversized boss units, which go down fairly easily to one of the other secret characters who has units with ranged attacks, provided that you attack the boss at night because they're undead). One of these has an accessory that gives him double movement range... which you can unequip after he's done moving and put on another unit. There's several mid-late game maps where you can just walk over and capture the enemy base on the first turn because you have the extra movement range.

Hilariously, the secret characters who join later in the game are so much weaker than the ones who join early I never even bothered using them.
