Lord Franken-Format (The Toxic Feeder)

Nemesis
Optimus Parse (The Data Transformer)
Superpower
Force-feeding pipelines an unholy amalgamation of unstructured APIs, TSVs, YAMLs, and nested XMLs stitched into a single, incomprehensible payload.
Backstory
Born from a neglected, malformed Excel spreadsheet in 1998, the Lord hates standardization. He thrives on chaotic column names, missing headers, and format switching mid-stream. He sneaks into pipelines when bioinformaticians aren't looking, cramming machine learning models with a Frankenstein-esque buffet of garbage data until they choke.
Catchphrase
"Why choose one standard when you can have pieces of ALL OF THEM?!"
