Connections to Universal Animation
Although this is a Disney animated film, Big Hero 6 has some elements and similarities that are closely connected to Universal Animation Studios:
 * The film features a young protagonist, a tradition that Universal Animation always does in most of their feature films.
 * One of the film's writers, Jordan Roberts, previously wrote the screenplay of Universal Animation's 2011 film Gabriel Garza. Speaking of which, Alan Tudyk, the voice of Alistair Krei in the film, also voices Loy Garza in the Gabriel Garza reboot films.
 * Maya Rudolph, the voice of Cass Hamada in the film, previously voiced Samantha in Paint World and also did the voice of Queen Melly in Universal's 2015 film Paradoria as well as Sally in Universal's 2016 film Imagimals.
 * An unrelated animated film based on Big Hero 6 that was going to be produced by Universal was in development since the early 2000's but was cancelled due to story issues. After that, no official Big Hero 6 film was announced until June 2012 by Disney and Marvel.
 * In fact, Universal even uses the Hiro Hamada character under license from Disney. Because of this, Hiro appeared as a minor character in the 2018 Universal film Computeropolis: The Deep Web.
 * This is also because of the increasing popularity of "Liro", an internet crossover fan-fiction relationship between Hiro and Leno Garza, a character from Universal/Gingo's Gabriel Garza franchise, as they both share the similar appearance and characteristics.
