I don't think people realise how op fully maxed limbs of jacob from fate are since if it it allows for a person to imitate the power of a archangel from fate who are entities on a divine spirit or higher level. Like king hassan only has a small power of azrael and he already qualified as a grand heroic spirit.
I had some doubt about asking if you could put in the Throne of Heroes another character from another series but, since you put Raiden Tameemon, I want to suggest Kim Woo-Jin (from “Kill the Hero”) since he is very OP in combat but I don’t know how to claasificate him because he is almost a jack in all trades and almost master in all: from caster, to assassin or all the other type of Servant classification.
