Tiamat from Fate series
Personality: Something like a personality cannot be confirmed from her. Whether Tiamat has lost her ideals, or whether she has no reason since the beginning, it can be interpreted as either way, but one cannot surmise the reason. Although she simply birthed, raised and loved her children, which was viewed as her only meaning in life, she has set out to fight against humanity, of whom they decided that for the sake of denying this meaning, they have declared "you are not needed." Her behavioural ideology when becoming a Beast is extremely simple; she runs under the extremely primitive system of "If I do not kill humanity, I will be killed."[1][4] Concerning Tiamat's motivation and attitude towards the Master, he/she is one of seven billion humans, naturally a target for obliteration. As far as human beings are concerned, Tiamat is a repulsive aggressor (invader), but concerning Tiamat too, human beings are terrifying aliens (extraterrestrials).[1][4] Because Tiamat cannot converse, her pronouns are unknown.[4] In the Babylonia anime, Ritsuka Fujimaru during the final battle against Beast II encountered a mental projection of Tiamat in her first form. Somehow she was able to create a mental connection to him. Tiamat lamented that her children used her as a stepping stone, leaving her behind and that all she wanted was to be by their side. After asking if her love was wrong, Ritsuka chose not to stab her like her previous children (the Sumerian Gods) and instead told her that her children loved her and that they had to "get going". In other words he thanked her for a Mother's Love as humanity grew up but now that they were adults she had to let them go. "Please don't leave me. Please never... love me again." In the end, Tiamat asked Ritsuka to not leave her behind and that if he (humanity) had to do so, to not love her again.
