Fortress Saga tier list - Ranking every hero

Want to know who you should deploy to protect your walking fortress? In the Fortress Saga tier list, we ranked all the heroes in the game so you can have a clear idea of who should be out on the field, and who you shouldn't bother with (at all).
There are a lot of heroes in Fortress Saga. Many of them are good, but you do not have access to all of the good ones from the beginning. So, as is the case most times, you will probably end up upgrading some of the lower-rarity ones because you have no other choice.
Even if that is the case, the heroes that are ranked at the top of the Fortress Saga tier list are the ones you should try obtaining and upgrading ASAP. The second you get some of them, the rest is history. That's when the real game begins.
Since the game has been around for a while in Japan, this tier list is based on that and I have adapted it to the Global server. I have also added explanations for some of the heroes underneath each tier, so if you're curious as to why some of the heroes rank the way they do, all you have to do is keep reading.

Can you reroll in Fortress Saga?
Some people might wonder about rerolling in this game, and that is just something not worth your time. At the beginning of the game, you don't have access to all the heroes anyway, so rerolling would just delete all your progress, account and everything else, while not providing any "good" heroes anyway. So, don't bother thinking about rerolling in Fortress Saga.Now that we got that out of the way, let's dive into the actual tier list so you can have a clear idea of which heroes to use on your team!

As you can see, a lot of the other heroes land at the bottom of the Fortress Saga tier list. These are the heroes you should not bother with at all, regardless of their rank/upgrade status. There are plenty of Unique and Rare heroes in the higher tiers that you can focus on upgrading, so in my opinion, you shouldn't bother with these at all.
If you need to use some of them until you get an upgrade, that's fine, but otherwise, just try to not invest anything more than necessary into them because it's a waste of resources.
You can take a peek at the Disney Pixel RPG tier list and other similar ranking guides, like Castle Duels tier list. We have a lot of them, surely there's something that will draw your attention.
