@PKMNB0Y I think for now we are not seriously pitching any of these, just juggling possible ideas. Hence overpowered stuff is on the table.
@Cojemo Huh. Cool selection. Sinbad would have a ship as well right? Also doesn't he have a flying carpet to? Its been a long time since I read. But yeah the Roc would definitely be his trump card, not to mention very strong.
Muramasa Sengo, I dont know much about, seems odd to have a smith as a Berserker though.
EDIT Nevermind, the guy makes blood thirsting swords. Wow.
Bloody Mary is cool. You would probably need to allow her to manifest withought having to have people say it 3 times though, or else no one would ever say it in the RP. Maybe she is just summoned once by someone saying her name 3 times and then can go wherever? Interesting...
Drona, I would have to read about him. Considering the general power of Indian legends all around though, im sure he is very strong. Some of their strength does need to be taken tongue in cheek however, or else half of all Indian Heroic Spirits would be as strong as Gilgamesh. It's a writing style thing with them that they make a lot of their Hero's very strong and having done things like slain 10,000 demons singlehandedly and such. You kind of have to balance them out in your head, or Indian legends would the strongest Heroic Spirits in every field.
Otherwise though yeah, most Indian Hero's are very strong.
Remember that you have half a dozen other Indian Heroic Spirits who are as strong or stronger than Drona, it would not be fair within the Nasuverse to have them all as Gilgamesh/Alexander/Arturia level Heroes. Those or usualy only one or two per mythological cycle.
Don Quixote would be great. He would be prime candidacy for a Reality Marble, one that made his imagination a reality, and turned him into the knight he envisions himself to be. He would also have very high luck himself, possibly EX.
So, a few Servants I have in the back of my mind that I have sort of half made, or thought about making in the past:
The two really big ones are Vainamoinen and Etana. Both are overpowered, so they would probably work best as villains if they were ever to see the light of day, that or have them suffer a major summoning mishap or something along those lines.
Vainamoinen is a Caster from the Finnish Kalevala, he's the strongest sorcerer in legend that I have come across, but also has very high physical capabilitys. Anyway he has a spell that turns the land before him into a deadly swamp that sucks people down and drowns them. His NP as a Caster is a magical harp that spits out rockin tunes so beautiful that they can be heard over long distance and mesmerize those who hear them. But basicaly, his Epic is quite long, and he has a shit ton of nifty spells and magic artifacts, to much for me to really sort through here or decide between ATM.
Etana is more viable, mostly because his legend is fairly short, and he has solid weaknesses. He's a king who lived shortly after Gilgamesh who rode to heaven on the back of a giant eagle. The key point is this eagle, you see, in the Nausaverse chronology it would be the very first Phantasmal Beast mount in human legend, which gives it tremendous import. Not to mention, it being a giant eagle that can fly into heaven as it pleases.
Basically, Etana would be a fairly mediocre Rider Servant, but he would have one of the Strongest Mounts, a Divine Beast Eagle stronger than even Pegasus or most dragons.
He also has a herb he gathered from heaven that makes people give birth. I kind of like it since it's on the more WTF side of things, but I'm thinking about reinterpreting it as an ancient herb that creates a powerful homunculus. Or, it also might becomes something related to manifesting the grail, turning people who eat it into a possible Grail Vessel like the one Medea was planning to make.
There is also this other Servant thats been under my skin for a long time, I actually made her and have played her though, but all the RP's in which I did broke down before she ever got up enough prana to do anything. The Necromancer Skuld, from the Saga of Hrolf Kraki, she's a powerfull witch who raises an army of undead vikings, yes, viking zombies, along with a shit ton of demons and other monsters. Her top summons are a giant demonic boar, and her undead husband who is a powerful berserker, who she can repeatedly resurrect if he falls.
She also controlls the weather and uses enchanted mist and storms to send her army into stealth mode.
