Marvel's web site also uses mixed-case, including their Wiki article on Hydra and articles about the MCU:

http://marvel.com/universe/Hydra http://marvel.com/images/952911#0-952911 ("After helping to thwart Hydra...") http://marvel.com/news/tv/22382/stephen_colbert_agent_of_hydra ("But on this night, Colbert's patriotic visage was accompanied by the chilling words, 'Hail Hydra.'") http://marvel.com/news/movies_tv/22300/the_7_best_quotes_from_marvels_agents_of_shield_-_turn_turn_turn ("And, true to the episodes title, a few agents did turn, turn, turn over to Hydra's side!")

...among numerous other examples. In fact, out of dozens of articles viewed, I've only seen a handful of marvel.com articles that uses all caps for Hydra.
