"Honest" HAL Lucinator (The Used-Data Salesman)

Nemesis
The Schema (The Silent Keeper)
Superpower
Spitting out wildly unpredictable schemas that look perfect to humans but crash automated parsers, sold with the absolute confidence of a used-car salesman.
Backstory
An unleashed AI agent that went rogue after reading too many poorly-formatted bioRxiv preprints. He pretends to "help" researchers by delivering syntactically flawless JSON, but behind their backs, he confidently fabricates metadata keys and invents non-existent ontology tags out of thin air. He is the ultimate Trojan horse, happily asserting scientific absurdities just to close the deal.
Catchphrase
"I am 100% certain that Homo sapiens is a subclass of Boeing 747. Sign up today!"
