Oh wow. that was quick. 3 days before the Christmas Heroes and already they shown the heroes. It's Lissa, Chrom, Robin and Tharja. To make a long story short:
-All of them are Armored units.
-Lissa and Chrom are Axe users. Lissa uses a Bell and Chrom uses a Santa Bag.
-Robin is a Lancer user. Uses the Christmas Tree.
-Tharja is a Red Tome user(and is even more revealing) and uses a Candelabra.
-All weapons give +2 to all stats when combat is initiated by the enemy.
-Lissa actually has a B-Skill that is the counterpart of Quick Riposte. At above 80% HP, you're guaranteed a follow-up attack! And it gives a Special Charge+1 per attack! But it doesn't stack with Heavy Blade or Flashing Blade.
-Tharja gives a B-skill that is a stronger version of Quick Riposte At above 50% Hp and when attacked by the enemy, you're guaranteed a follow-up attack and gives a Special Charge+1 per attack. Once again, it doesn't stack with Heavy Blade or Flashing Blade.
-Chrom's unique A-skill is Brazen ATK/DEF. At under 80% HP, it gives ATK/DEF+7 during combat.
-Robin's unique A-skill is Brazen ATK/SPD. At under 80% HP, it gives ATK/SPD during combat.
-As for other skills, Lissa has Bonfire and Fortify Armor. Chrom has Pivot and Wary Fighter. Robin has Reciprocal Aid and Armor March. Tharja has Iceberg, R Tome Valor and Close Counter.
-Tharja's title is "Normal Girl." Anyone who's read Tharja's support with Robin should very well know what it's talking about.
Either way, can I just say on why did IS do this? They are all Armored units, yes. But....
-First of all, those Brazen skills can combine with Desperation. They are pretty much Lyn's dream A-skill! She can attack any unit under 75% without giving them a chance to counter AND get +7 ATTACK AND SPEED. Who thought this was okay?!
-Lissa's B-skill is Quick Riposte, but for attacking rather than baiting. Not only that, but it gives Special Charge+1! This allows Brave users who survive a hit actually Double AND use skills like Ignis, Glacies or even Galeforce. That is terrifying! But only if this can be transferred to non-armoured units. I just noticed it's title is Bold Fighter, much like Wary Fighter. So this could be restricted to Armoured units. Effie and Draug could still make good use of it, as they both make good use of Brave weapons.
-Same goes for Vengeful Fighter, which is Tharja's B-skill. It's practically a stronger Quick Riposte that gives +1 Special Charge. If only for armoured units, this is still a big buff for them. Hector would be terrifying with it, as it would allow him to hit with Ignis. Same goes for any Armoured unit with Distant Counter/Close Counter.
-Anyway, looks like we have to see how the Brazens and Fighter skills will be handled with Skill Inheritance. If Bold & Vengeful fighter are stuck with Armoured units, we're somewhat safe. If the Brazen skills can be SI'd to non-Armoured units, Lyn is about to get much better, as well as other users of Desperation.
Anyway, I want Lissa, as she is a Bell Axe wielder, even if she is Armoured. Although she's stuck with Chrom, as he's also an Axe user(which is strange cause his Spring version was already an Axe user, why an Axe user again?). Robin and Tharja are separate though, both being a Blue & Red respectively.
