Villain probability
58%
Basis: phonetics. One voiced obstruent, one bilabial stop, one sibilant, ends on a consonant. The canon has no entry, so this is the sound of the name and nothing else.
Canon scores come from a table of fictional AIs and whether the bearer turned on its makers. Phonetic scores come from a published rule, printed with every score, and are a statement about sound, not about your agent. How the sound is scored.
