Nyx(colorless tomes) for more of that tome variety, likely very focused on attack and low defense, equal speed and resistance.
Niles(red bow cav) For diversity and I haven't ever seen one in heroes. Has the capture bow, causes enemies hit to be pulled one space towards him if possible.
Benny(Lance armor)- High high defense and hp. Also the demote of the banner with bold fighter and attack smoke. 100% demoted
Charolette(axe infantry)- High attack and high speed, low defense and resistance. Basically to represent how she was strong enough to massivly take out hp but lost in terms of defensive capability to others.
GHB Sumeragi(sword infantry)- Has a better rajinato, and high attack and speed with okay bulk.
Marriane(sword cav)- She is a cav cause she likes horses and her weapion would have adaptive damage and beast effectivness.
Rapheal(First ever brawler)- Justy want brawler in the game, and he would have the highest hp possible. And hope brawling weapons automatically get effective against infantry.
Hilda timeskip(Axe flier)- Highly competitve but likely going to be premium unless marriane is.
Lynhardt(eithier green infantry mage or staff)- A demote whose prf weapon gives allies buffs during combat. Kind of like seteths weapon but +6 speed and attack. Probably high resistance, since ingame he has a really good growth of it.
Dedue(Axe armored)- When he comes, is will make this guy a armored unit. and the ghb with a gaurd axe to just hate on him. Thats a guess but Hope he has a prf weapion that gives hime more defense when in combat with a lull skill.
Selena(Red bow cav)- Premium unit with death blow and close counter built into bow. I dont rwally got a skill set for her but she would have decent res and defense at least.
Viake(Axe infantry)- High hp and high attack. Prf weapon hopefully a brave axe effect.
Kellam(Lance infantry)- GHB unit and would have a skill that nullifies half of damage for the unit on first hit and can only go to armors.Restriction: Hp=100% This is so that he can show that he often is forgotten and even the damage forgets he is there.
Laurent(Green tome mage)- Wouldve said red but the baner has selena. He will be demote
Noire(Colorless bow)- has petrine lance but as a bow. She gets null follow up and savage blow 4
