"Issue 188" is the second Season 1 episode of Big Hero 6: The Series. It premiered on June 9, 2018.

On February 15, 2018, the episode was first released on Disney XD's UK YouTube account before making its television debut.


Go Go and Fred dive deep into comic book mythology to try to find a way to defeat High Voltage, a mother-daughter duo who use electricity and the art of dance in their crimes.


Professor Granville brings Hiro to meet Karmi, who was previously the youngest student to be admitted into the San Fransokyo Institute of Technology until Hiro came along. As they are both young geniuses attending college, Professor Granville believes that Hiro could do with some socialization with someone his age. Karmi seems very optimistic about making friends with Hiro, but when Professor Granville leaves the two to get acquainted, her tone suddenly changes to not wanting anything to do with Hiro, preferring to keep to herself and work on her research. Hanging around Karmi's lab, Hiro learns that she is into biology and has developed the habit of talking to her virus samples, as if they were people. Hiro's attempts to be friendly are met with hostility by Karmi.

During night patrol, Hiro learns from Go Go that Karmi has no friends, and took pride in being the youngest genius in the school. Baymax alerts them of criminal activity, and upon investigating, come face to face with the mother-daughter criminal duo known as High Voltage. The three heroes engage them as they rob a couple of automated teller machines, but High Voltage's combined electronic powers and dance moves causes them to lose the fight. Hiro and Go Go tell Wasabi, Honey and Fred about it the next day at school, and Fred draws similarities of yesterday's battle to a comic. Go Go sarcastically suggests they should study some comics to figure out how to beat High Voltage, which Fred takes seriously and suggests looking up Captain Fancy #188, where the hero lost battle after battle to a mother-daughter acrobat team, similar to High Voltage. Hiro, meanwhile, discovers that Karmi has a crush on him when he sees her drawing his superhero self in one of her textbooks.

The next night, Big Hero 6 engages High Voltage again as they're robbing a truck filled with money. Even with the whole team together, they fail to stop the mother-daughter criminal duo. Karmi gets a good look at Hiro's face when he saves her from a falling lamppost, but somehow fails to recognize him. Sulking over their defeat the next day at school, Go Go reluctantly decides to go ahead with Fred's idea in looking up Captain Fancy #188 for a way to defeat High Voltage. Unfortunately, Fred does not possess the issue, due to losing a bidding war over it when his power was cut out, and one of the only known copies in existence is in possession of his arch-rival, Richardson Mole. They visit him at his comic book store, and he grants them permission to read it, under the condition that Go Go wins at one of his Fred themed games. Meanwhile, Hiro starts to question Granville's decision in pairing him with Karmi, when he is already well adjusted in socializing. Baymax, however, points out that Karmi does not appear to socialize well with other people.

Big Hero 6 intercept High Voltage for the third time, while they are robbing a bank vault, but are once more unsuccessful in stopping them. Fred and Go Go arrive much later, after reading through Captain Fancy #188. Go Go believes Fred has found the answer to beat High Voltage, but, much to her annoyance, he only found the answer regarding Hiro being unrecognizable to Karmi while in his battle suit. Fred expresses disappointment in the comic, and gratefulness for having his power cut out so he couldn't buy it, which gives Go Go the idea to cut out High Voltage's energy orb that powers their electricity. Go Go instructs Honey to cover her discs with rubber goo, and to give her two rubber chem-balls. Go Go moves in, shielding off the duo's electric attacks, then confiscates and covers the energy ball in rubber, cutting off High Voltage's powers. High Voltage tries to escape, but Honey traps them both in sticky goo.

The next day, much to Karmi's shock, Hiro thanks Granville for having him socialize with her, citing that he had learned a lot, and does not reveal Karmi's less-than-friendly behavior. He also recognizes Granville's attempt at trying to help Karmi socialize, starting with him. Karmi, in turn, gains some respect for Hiro, but still somewhat looks down on him. Meanwhile, Obake is looking at pictures taken of Big Hero 6, then focuses on a close-up picture of Hiro and Baymax, with the episode ending on his face mysteriously glowing.

Revelations and Continuity

  • Hiro is revealed to be the youngest student attending SFIT. That recognition previously belonged to Karmi until Hiro was admitted.
  • Richardson Mole is introduced as Fred's arch-nemesis. It is also shown that Richardson has a crush on Go Go.


  • There are several fallacies concerning Karmi's knowledge of viruses, and with the safety of her lab.
    • While talking to one of her viruses, Karmi compliments it for having "junk in its nucleus." This is incorrect since viruses do not have nuclei or organelles.
    • Karmi's lab appears to have no isolation protocols, in the event that one of her dangerous, pathological, and highly infectious viruses escape.
      • In addition, visitors to her lab, such as Hiro and Professor Granville, should also be wearing safety equipment.
      • Due to the pathological nature of the viruses she is studying, Karmi, and other visitors, should be wearing biohazard suits. However, only Karmi is shown wearing one.
