- Genius-level intellect: Le had a confirmed IQ of 160 which is very high.
- Bilingual: as a BS in French literature and history Le was at least basically familiar with French language, as well as being Mexican-American he might have known Spanish as well.

- According to Waller's files he's a Mexican-American.
- According to same files he's an avid reader and a fine wine collector.
