ooh-wee, my initial comment was deleted by mod for veeery adequate reasons, so I'll go ahead and re-point out how Echidna shares a curious resemblance with Orochimaru (also ENTP 5w4) in having conducted experiments to prolong her existence in the mortal realm. She is a bit of a benchmark for this subtype - a character realizing how limiting the very laws of their world are and ending up in a committed search for a way to alter something about these laws (which makes them all somewhat resemble INTJs btw). Makishima Shogo (Psychopass) is another good example of this subtype, and, in turn, Jibril (NGNL) is a bit of a worse one. Honestly, Dona was an addition to it that definitely deserved at least a bit more screentime.
