I am wondering who are the worst FE units of all time. And picking the 34 worst of them to see if they can beat Sacred stones if i just replaced the roster with them and see how much harder the game can get. And while we are at it the best 34 units as boses because why not. So far my list of who is replacing who from the original game (warning. i have only played the DS, GBA, SNES (exsept mystery of the emblem), And verry little of Path of radiance and gaiden):
Erika = Lyn
Seth = Wallace (lyn mode)
Franz = Matthis (fe 11)
Gilliam = Wendy
Molder = Maria (fe 11)
Vanessa = Sheeda (fe 1)
Ross = Darros (fe 11)
Garcia = Johalavier
Nemi = Wolt
Colm = Daisy
Arthur = Sophia
Lute = Miranda
Natasha = Wyrs
Joshua = Samto
Ephraim = marth (fe 11)
Kyle = Kain
Forde = Alba
Orson = Asstram
Tana = Hermina
Amelia = stays the same
Dussel = Lorenz
Cormag = Horace (after being moved to not be stuck)
Innes = Asellio
Gerik = Amid
Thethys = Karla
Marisa = Atlena
Le’archel = Jeanne
Dozla = Ymir
Saleh = Hugh bought with least cash
Ewan = Yubello
Renac = Rickard
Knoll = Pelleas
Myrrh = Bantu
Syrene = Hanibal
Gotta have Shannam in there. I am positive he was meant as a joke character in the bad way
Jeanne is one of the better replacements units.
Deimne is the worst one (FE4)
I think NES Wrys sucks
This gives me the head cannon that Lyn and Marth are distant siblings
Johalvier’s underrated. He’s not excellent, but he certainly isn’t trash. Especially if you don’t pass down the Paragon Band, in which case it starts in his inventory. Bow access is also nice.
FE3 B1 Arran is what a trash unit actually is. His bases are mediocre and barely serviceable, he’s forced to dismount for half the chapters he is available for (including his join map) with such horrid stats that make Samson look genuinely good, and on the few outdoors maps, his mobility doesn’t mean much of anything because of clumped enemies who will easily 2-3HKO him, forcing you to move slower unless your units are exceptionally strong.
The sequel of Fire Embad is coming soon!
Also, maybe we could have some of the FE6/7 axe fighters in here, mainly Wade or Dorcas. I’m not joking lol, they are bad units (thanks to their low stats, mainly at speed and skill, things that you actually need when you’re an AXE user), even when their counterparts aren’t exactly good either, or even in the case of FE7 where axes are supposedly better than before (spoiler they’re not. It’s just some of the better units like Hector and Marcus coincidentally can use axes without their main drawbacks).
Dorcas has good bases and Lyn Mode availability that crutches him through a lot of the earlygame, axes aren’t the inaccurate joke in 7 that they are in 6, and Hector Mode gives the player a Silver Axe in Chapter 15. Hector and Marcus are better, but then Hector’s a Lord with an Axe Rapier and Marcus is just one of the best units in the whole game.
I’d go with FE7 Bartre and Karla, for obvious reasons. Also Meg for being Wendy in a situation with vastly less room to tolerate babying a character with no worthwhile payout whatsoever. At least Fiona has her niche as an alternative for Nephenee.
For what it’s worth, two other people have already implemented this concept; one for fe6, and one for fe8.
I think minimum Hugh is a bit out of place in this list. He’s just kind of okay, but he’s not, like, unusably bad.
Lyn mode Wallace is stellar in the context he’s in (Lyn mode) and doesn’t really fit Seth’s archetype. I’d maybe substitute someone like b2 Samson in for him.
A, uh, large portion of these units are Arachnean, with only token representations from other games. Perhaps it’d be best to embrace it and narrow the hack’s gimmick roster to be solely bad/mediocre Arachnean units?
I love it, but make absolutely Sure that darros has 0 Con to reflect his fe 1 Power
A little sad to not see my man arden
hey look my hack 2 electric boogaloo
you are insane, Jeanne is quite terrible with no skills or really anything unique besides being a mounted healer (still fine! Just nothing to really get excited for) and Deimne is just flat out better than Lester in almost every way
Deimne is worse because he doesnt have a cool headband like Jeanne
Deimne is good by substitute standards but he, and Bow/Arch Knights in general, are massively overrated.
A huge part of what makes Deimne anywhere remotely viable is his early substitute event in Issach Castle giving him +5 Strength. However, the downside of being a substitute is that his weapon options are horrible. Even if he has ~15-16 STR by the end of Ch6, he only has 30 ATK with a Steel Bow at the start of Ch7, which is barely adequate to ORKO stuff, and his low Speed stops him from doubling and killing enemy sword users. The two best bows in the game, the Brave Bow and Killer Bow, are not available until mid-Ch8 and the end of Ch8 respectively, and both are carried by Generals that Deimne struggles to kill reliably, forcing him to shell out money.
Deimne is also useless against bosses, for which Gen 2 has very in very high quality. Any notable threat that needs to be handled like Ishtore, Blume, Ch8 Ishtar, Riddell, Hilda etc all either kill him with magic or double him because of his low speed. Deimne also falls off in the late game due to his poor class caps.
At the end of the day, all Deimne does is take quite a bit of effort to kill one enemy per turn, and that’s it. All at the cost of not getting Lana (who is superior to Mana) and not passing down Edain’s inventory of good staves. Even Lester falls into the same pitfalls with optimized inheritance, because no matter how much you train him or pass down good stuff, Lester will be handicapped by only being able to fight one thing a turn, and being worthless against bosses because of Arch Knight’s horrendous caps. Lester will always be mediocre even at his best, so at that point, why bother making him workable to begin with? Just dump all the investment into Lana with something like Claud x Edain for early Rescue, or failing that, whatever passes down good money supply to Lana so she can repair staves before she gets a husband.
At the end of the day, if you’re willing to let Edain go unpaired or are dumping substantial effort into making Lester usable, you could be using the same effort into another unit with an actual enemy phase like Diarmuid, Seliph, Arthur or even Larcei (with Leg Ring investment) into a team carry that doesn’t have an artificial cap to their contributions like Lester/Deimne do.
Oh my god yes. He’s gotta be the worst unit of all time.
Amelia = stays the same
Poor Amelia. She’s so bad, she’s the only character native to FE8 that gets to stay 
That “honor” pretty much objectively goes to fe12 Lunatic Reverse Bantu, sorry. He can’t contribute against anything except archers because everything else vantage OHKOs him. His growths are horrendous. He can’t be reclassed. His weapon uses are limited, so you can’t even grind him with boss abuse. Every weapon use he uses is a weapon use that Tiki/Nagi no longer have. His firestone isn’t in his starting inventory (nor is using him required to obtain it), so unlike Sophia, he can’t even claim that he at least gives you a good item.
Arden. His wrong class in wrong game. his an armor knight in horsey Saga.
I wouldn’t know because I haven’t played that, but I believe you.
I can fix him
