Brainiac

12th-level intellect

For comparison, the population of 20th century Earth as a whole (excluding superhumans, other robots or cyborgs, nonhumans, Lex Luthor and other outliers) constitutes a 6th-Level intelligence and the population of 31st century Earth as a whole is a 9th-Level intelligence.
