Heh, yeah, kigurumi can be creepy.
Summoning Gilgamesh instead isn't all that different, though I have to question why all their Archers use swords. Imagine heroic spirit EMIYA summoned as Saber by Shirou.
That'd be a riot.
Still, this gives us several versions of Rin(some are overlapping abilities, as apparently shes a polymath), but at the least they don't deviate as much as the 3 Shirous:
Fate/Stay Night(Fate):
Demonstrated Reinforcement magic on her own legs, giving her minor superspeed.
Has 10 gems charged with 'A' rank magic, which have been used for an
attack of ice, a protective spell(to protect her from being crushed by Berserker) and what looks like raw magic blast on Berserker. 4 gems killed Berserker once, Ilya implies that using 8 gems at once may actually have removed 2-3 lives.
Explained that each gem is destroyed after use(boy, that must be harsh on the family finances)
Fate/Stay Night(Unlimited Blade Works, as far as I know):
Demonstrated the
ability to cast Gandr shots rapidly. These appear to be nonlethal knockout rays at first, though once she lost her temper they started doing physical damage. Does not use gems. Has a gatling gun version powered by her family Magic Crest
Gems used for counterspelling instead, each gem is good for 3 personal defense counterspells, or 1 general purpose counterspell, agaisnt Servant Caster.
Knows Kung Fu Gems(unknown number), used to augment her fists. Then she punches the shit out of Caster.
Fate/Stay Night(third hand knowledge only):
Gets Shirou to make the Sword of Zeltretch.
Grafts Archer's arm onto Shirou to let him use Unlimited Blade Works
Uses the Sword of Zeltretch to lay down beamspam.
Fate/Hollow Ataraxia(third hand knowledge only):
Kaleidostick obtained, is sentient, is perverse.
Magical Girl Kaleido Ruby
Battle Moon Wars(third hand knowledge only):
Kaleidostick + Sword of Zeltretch = Wave Motion Gun
