Abigail Williams (rosebud) (kick to the beat)

Personality: Abigail in this form is relatively nice to everyone but her grown up form, she has a deep seated hatred for the person she was destined to become and does everything she can to make her full grown versions life a living h*ll other than that she's pretty much the same as Abby in that she's nice but not without a sense of mischief
Event ability: kick to the beat (both she and her opponent can only attack if it's done along with the rhythm of whatever song she's playing)
Hidden abilities: alterer
The crucible (does double damage against casters, takes half damage from casters and warriors, does double damage against good servants)
Class: alterer
Grand magic: a spring of joy
Characteristics: rose bud, American, witch, human, alterer
Alignment: chaotic evil
Rank: EX
Rank explanation: kick to the beat is by far the best defensive ability out of pretty much every ability so far, it allows Abigail to attack relentlessly and take away her opponents ability to counterattack effectively, the crucible is also nothing to sneeze at as it limits the amount of servants who would be effective against her, her grand magic is almost useless however, spring of joy makes every servant around her a "witch" and boosts the power of caster class servants slightly

Shammuraut/Semiramis (perfect form) (2 in 1)

Personality: a version of shammuraut that doesn't exist anymore from back in the days where the legend of Semiramis was still under her control, she is undeniably one of the strongest servants involved in this war, she is pretty much just regular shammuraut in terms of personality with some breakthroughs by Semiramis

Izami pieces (MAO) (a misery so lovely)

Personality: a version of izami from the future about 5 years out of high school, her stories a little long to explain here so we'll wait till later, she was summoned as a berserker so she has some lapses in sanity but she's mostly the same old izami
Event ability: a misery so lovely (she's on a timer she has about 2 weeks before her grand magic will kick in and kill her, in exchange though her power is triple that of a normal berserker)

Weapons: various
Rank: EX
Rank explanation: even though she isn't going to be around long term unless someone can find a way to slow down her grand magic, she is still an extremely potent servant and Yggdrasil is an incredibly powerful grand magic to top everything off

Scheherazade (alter) (short nights and long days)

Personality: the assassin of Arabia doesn't change much as an alter, she is still willing to do anything to survive and she's incredibly resourceful and maybe even a bit sadistic
Event ability: short nights and long days (she has double the attack power during the day and double the defenses at night)
Weapons: poison powder, paralytic powder, Arabian dancer dress
