Dr. Horace Diaz is a major recurring character in the series, Mighty Med. He is the hospital’s Chief of Staff, and is Caduceo, the legendary healer of superheroes. Horace is portrayed by Carlos Lacámara.


Past & Background

Horace was born almost 3006 years ago in the year 991 B.C., and eventually became known as the legendary healer of superheroes, Caduceo. Gifted with the power to restore a dead person to life five times, he used three of them at various points during his life and the fourth to save Skylar Storm's life. He also battled and defeated the supervillain Catastrophe, splitting him into Wallace and Clyde and retaining half of Catastrophe's Dyad of Nebulon. He went into hiding, and the hospital Mighty Med was established in honor of him. At some point he was appointed Chief of Staff of the hospital, and never told anyone his true identity. In 1953, he ran into trouble with two time travelers, who would become his future employees. His sister married the superhero Optimo and gave birth to Alan Diaz, Horace's nephew, whom he was charged with raising to keep him safe from Optimo's nemesis Razor Claw.

Present Day

Horace was at Mighty Med when its existence and location were discovered by Oliver and Kaz, a pair of Normo boys who were huge comic book fans. He hired them to work as doctors at the hospital.

However, Horace's fate is unknown after Mighty Med was destroyed by Roman and Riker. However, he might have survived, although Alan and Optimo's fates are unknown as well.


Horace has a goofy personality but he does possess a serious side, especially dealing with villains. He's always cracking jokes and loves bridges. He is funny and always gets the job done. He has trained for years as a medical worker to work at Mighty Med. However, his punishments are extremely Draconian--failing an exam or breaking rules are met with cubing.

Most of the time, Horace is shown to be eccentric, over-the-top, and extremely arrogant. Horace's arrogance can at times work against him, as he can be overly confident and unwilling to admit his failings. Although at times he can be uncaring, selfish and greedy, Horace is also genuinely nice and a kindhearted man, who loves family and cares deeply for Alan and also Skylar, seeing her as a daughter. Despite his childish, egocentric personality, Horace always puts the safety of his family and workers as his top priority.


Oliver (Good Friends/Ex-Future Step-Son)

Horace is good friends with Oliver and was immediately impressed by his knowledge of superheroes. Horace also doesn't seem to get annoyed by Oliver. Because Horace is engaged to Oliver's mom, Oliver is his potential stepson, and starts acting like a father to him.

Kaz (Good Friends)

At first, Horace disliked Kaz and didn't want to hire him until Oliver changed his mind, After Kaz saved Tecton's life, he finally trusted him. However there are times when Kaz disobeys Horace's orders.

Skylar Storm (Good Friends/Honorary Daughter)

Horace has a strong friendship with Skylar and in Evil Gus, when Horace acts like Skylar's dad, it made him realize he wants kids really badly. Despite being good friends with Skylar, in the Season 1 finale, Horace was fine with kicking Skylar out of the hospital and finds her very greedy.

Alan (Nephew)

Horace is the uncle to Alan. Most of the times, Horace gets annoyed by Alan's selfish and annoying behavior, but deep inside he truly loves him. In fact, Horace is concerned for Alan's well-being in order to protect him from Razor Claw.


  • Chronokinesis: He can control the flow of time. This allows him to switch clothes with other people faster than a blink of an eye.
    • Temporal Speed: He can slow time down around him to give watchers the illusion that he moves at super speed. (This is not technically speed, but it does give off the illusion of speed.)
    • Temporal Stasis: He is able to freeze someone in suspended animation, however it only works for a short while (depending on the person he uses it on), or as long as he can maintain it.  In There's a Storm Coming, it shown that he can sometime slow people down as he tried to freeze Skylar but his power was weaken and he only slowed her down.
  • Immortality: Caduceo is immortal, and is at least 3000 years old. He is 3007 however he tells Bridget he is 3047 possibly to date her.
  • Healing/Supernatural Surgery: As the legendary healer, he possesses the ability and extensive knowledge to heal even superheroes. Horace can use his knowledge of healing to restore a injured superhero back to their normal health. He can perform supernatural surgery, augmenting physiology/powers and possibly even give new powers/abilities. He can treat incurable diseases/ailments and reanimate/resurrect the dead.He can instantly understand the healing properties of subjects in one's environment.
    • Resurrection: Caduceo is the only being capable of bringing people back to life. By chanting the words "Thanatoi bios, bioi thanatos!", a caduceus (a wand with two serpents twined around it) appears, and brings a subject back to life. However, he was only able to this 5 times, and now he has none left. It has a horrible irreversible side effect; he gains a pound right in his hips, and it is very noticeable. He is unable to this anymore as he used the last one on Bridget and his second to last one on Skylar. It is currently unknown who used it on the other 3.
  • Superhuman Intelligence: Horace is a very intelligent man in many disciplines, and does his own research. However his childish and goofy personality can make him look like a dim-witted man. In addition, he is not smarter than Chase Davenport. In addition, he is unfamiliar with the concept of bionic technology, rendering him useless when the patient is bionic.
  • Super Hearing: In New Kids Are the Docs, Horace was able to hear the kids whisper from afar.

People He Has Used His Caduceo Powers On


  • Electric Fields - His powers are blocked by electric fields.  
  • Mirror of Zalkanikus (formerly) - If a superhero looks into it, their powers will be drained-no longer a factor due to being destroyed. Now that the mirror is destroyed by Gus in Storm's End it no longer applies to him.
  • Arrogance - Horace is very arrogant, and at times seems to be a borderline egomaniac. Although most of the time he simply appears harmlessly eccentric and wacky, at times he can be greedy, selfish and jerkish. His arrogance also creates other problems, such as putting too much confidence in Mighty Med's security system, whose staff is competent half the the time. In Oliver Hatches the Eggs, it's shown on occasion he has a colossal ego, to the point where he wants to be in a movie "about me, produced by me, and starring me." (similar to Donald Davenport from Lab Rats)

In addition, both are portrayed to be childish.
  • He has a mug that says 'World's Sexiest Chief of Staff and Vice Chancellor of Medical Administration" which he bought at a gas station.

  • He is a terrible singer, to the point where Oliver says he is "butchering Beyoncé." (The Friend of My Friend is My Enemy)
  • So far, Megahertz, Catastrophe, Chaz and Brain Matter (while mutated) have shown to be resistant to Horace's time freeze.

  • He has a paddle-ball in his coat pocket. (Do You Want to Build a Lava Man?)
  • He's ticklish (Do You Want to Build a Lava Man?)
  • He is Caduceo, the legendary healer of all superheroes (Storm's End). For a while, no one in Mighty Med knew this. Unbeknownst to Horace however, Dr. Wrath knew his true identity and revealed it to the villain world.
  • He describes himself as "creepy and harmless" on his dating profile.
  • He might have chosen to date Oliver's mom just because her name is Bridget,, since it has the word 'bridge' in it.

  • He isn't very good at keeping secrets.
  • He wishes that Skylar and Oliver had stopped his pet shark, Dawg, five minutes AFTER Dawg had eaten Dr. Bridges.
  • Listening to Kaz beatboxing is torture to him.
  • It's unknown if Horace is still alive after the destruction of Mighty Med.
  • When Horace uses his Caduceo powers he chants this phrase, "Thanatoi bios. Bioi thanatos" Thanatos is the Greek God of Death. This chant translates to "life deaths. Death lives".
    • This could mean Horace probably has origins in Ancient Greece, over 3000 years ago
