Shammuraut (alter) (imperfect alteration)

Personality: she's a hollow shell with a servant's powers and the name of shammuraut, she is the result of an alteration gone wrong
Grand magic: queen of despair
Event ability: imperfect alteration (she has no characteristics)
Hidden abilities: blessed water rank A
Shining stars (she has double power when she can see the stars
Class: ruler
Characteristics: none
Alignment: true neutral
Rank: B
Rank explanation: she's just not a good servant in general, her stats are low due to her imperfect alteration, and while having no characteristics makes her immune to a whole lot of abilities and grand Magics it also takes away the ability of a lot of servants to support her, her grand magic can cause a servant to give up a fight but it won't deal any real damage

Achilles (brave admiral)

Personality: a version of Achilles who was accidentally mixed together with some random pirate, he is pretty much just Achilles though he has some pirate like tendencies like stealing gold and liking the water more than his old self
Event ability: brave admiral (all pirate servants have their strength doubled while around him)
Class: warrior
Hidden abilities: Achilles heel
Poseidon's blessing (a combination of blessed water rank EX and seven seas rank B ((has power increased when near the water)))
Grand magic: battle by the sea
Characteristics: male, Greek, pirate, divine, non-magician
Alignment: lawful good
Weapons: pirate ship, sea-fairer's katana
Rank: A
Rank explanation: he's a good warrior servant for leading a group of servants with the pirate characteristics but a lot of the other pirate servants have some strong niche that edge him out just slightly, Francis is strong against women and has strong defenses when fighting against them, Nemo does extra damage against other pirates, and Mary has more control over her ship than he does, brave admiral helps make up for the lack of a niche but only when he's in a team with pirates and Poseidon's blessing is another ability that can only be used near water which lowers its usefulness, his grand magic, battle by the sea is essentially his one-on-one (fake) grand magic that comes with his original form, except this time there's water in the reality marble, this does however make brave admiral useless

Semiramis (rosebud) (trickster)

Personality: a teenage version of Semiramis, she loves to have fun and hates anything to do with responsibility, she tends to not listen to her master unless she likes them, and she hates most of the other Sumerian servants
Event ability: trickster (she can manipulate her magic to teleport around any area that she knows the layout of, does double damage to any non-caster servant with her next hit for a short time after teleporting)
Class: assassin
Grand magic: maze of Babylon
Hidden abilities: clairvoyance (she can see over long expanses of land)
Bloodbath
Weapons: rose daggers, red rose chainsaw
Characteristics: female, Sumerian, rosebud, magician, queen
Rank: A
Rank explanation: she's a good mix of offense and defense, with her hidden abilities and chainsaw being useful for cutting down defenses and supporting a risky battle style, and her event ability, grand magic, and daggers are all useful for a more cautious hand defensive style of combat

Dean bloom (broken spirit) (MAO)

Personality: a version of dean from about 20 years on the future, a lot of stuff can happen in 20 years and a lot of stuff did and most of the cards dealt to dean in that time didn't turn out to be in his favor, he doesn't care much for his own life even as a servant but will fight to protect his master of any servant who reminds him of his friends or is one of his friends
Event ability: broken spirit (has no characteristics and does double damage against servants of the same class)
Class: none
Hidden abilities: broken circuits (he can choose which class of servant he wants to be but he cant change mid-battle, if he changes his class to something like berserker it can affect his personality)
Bloodied roses (if he's a berserker class servant he will completely lose his sanity out of grief and will attack anyone and everyone even his master but he has his power tripled)
Grand magic: a rose wilting in the rain
Characteristics: none
Weapons: none
Rank: B
Rank explanation: he's not all that great as a regular servant despite his event abilities because he's just dean, and dean doesn't have very good stats even with servant power ups, his grand magic is a variation of one of the finishing techniques his student form uses (a rose blooming in water) that can cause an enemy to become full of despair and give up similar to the altered assassin of Arabia's storyteller (alter) rank EX, his second hidden ability is where he shines but you can only utilize it once similar to the abigails demon's version of izami's grand magic
