Gaius - He's a quick oriented hard-support. He gens a decent amount of stars with NP and his skills make your team suck less.

Gilles de Rais [Saber] - He's trash. Don't use him until his strengthen quest, and even then, just don't.

Robin Hood - Single Target Arts-Nuke machine. Capable of triggering his NP's bonus damage on his own without support, and is decent otherwise. Real strength is damage.

Arash - He blows shit the fuck up. And then dies. That's about as far as his role extends, but damn if he doesn't hit pretty hard.

Cu Chulainn - He never fucking dies. Ever. His kit lets him survive for an obscene amount of time, and without any buffs, still remains one of the best in the current JP version.

Benkei - He's slightly better than trash. His kit revolves around stopping enemies from doing things, but he's nowhere near good enough at it to solidify a placement, even on gimmick teams. Can be used as taunt fodder if you need it.

ProtoCu - He's got the same NP and dodge as regular Cu, but more crit and beast-killing oriented. Slightly worse as a result.

Leonidas - He's a tank for Buster teams and is pretty good at base, but not the best until later.

Romulus - He never fucking dies, this time with an AoE NP without a third skill + Charisma dependant on NP.

Medusa - Quick-oriented AoE. Can stun but not too terribly amazing at base.

George - The BEST tank at base. Budget as fuck and has everything a tank could ask for, except his NP's more focused on synergy with Siegfried.

Edward Teach - Until Drake gets in, this guy's your best bet at a Buster Rider. He makes your team less shit and pumps out decent damage.

Boudica - A discount Mash without the good shit.

Ushiwakamaru - NP hits like a damned truck, but lacks a bit in other areas until later.

Alexander - Like Medusa, but a bit less selfish and his stun is more situational.

Medea - Instant NP that removes buffs.

Gilles de Rais - Not as bad as Saber Gilles but he certainly ain't winning any awards with his debuff-oriented Buster shenanigans.

Hans - Best budget support in the game. Good on most teams, but great for crit teams especially.

Shakespeare - Buster-oriented support. Doesn't get real good enough until later, but for now is pretty good at his job since he doesn't have anyone to really compete with.

Mephistopheles - He's like Gilles, but a bit more crit and about as meh.

Mozart - Debuff-Oriented with an Arts steroid. Pretty good in certain setups, but UTTERLY meh until later.

Caster Cu - Crit-Oriented Caster with that signature Cu Survival.

Kojirou - A crit monster that can do everything on his own.

Cursed Arm Hassan - A crit monster that helps his team more with a bit of survivability.

Jing Ke - Gens a ton of instant stars, but kills herself too easily and has no third skill.

Sanson - Good at killing evil/human enemies and a tiny spec of healing, but not much else.

Phantom - Bad. Don't touch him.

Mata Hari - debuffs but not much else.

Lu Bu - Single Target nuker.

Spartacus - Tries to be a 'Never fucking dies' but is a berserker with 1-star stats, so he can't stack up.

Asterios - Amazing in a very specific debuff-oriented setup, but otherwise takes too much effort to work.

Caligula - Can stall on occasion and hit things decently hard, but he just can't stack up without a third skill.

Darius III - A full set of skills and can survive a decent chunk of time.

Kiyohime - Has a big HP stat, but doesn't get great until later.
