Comic Book Series
One of the first villains ever to menace the Teen Titans, Mad Mod (real name Neil Richards) was a Carnaby Street fashion designer with no actual superpowers of his own. His assumed name is derived from the Mod style popular in England at the time. He used his label as a front to smuggle goods inside his clothing. After being foiled, he later hatched a plot to steal the Queen of England's scepter, but was stopped as well.
In later years, he went straight and reappeared in Teen Titans vol. 2 as an ally of Mr. Jupiter, where he designed the costumes of the new incarnation of the Titans. Mad Mod label "retro" clothing has occasionally been seen in the DCU since.
The term "Mad Mod, Poet God" was used by Peter Milligan for the unrelated DC character Shade the Changing Man. Another unrelated DC character is the "Mad Mod Witch" from The Unexpected, later revealed to be a resident of the Dreaming known as "the Fashion Thing".
Teen Titans Go!
Mad Mod made an appearence in the DC Kids and Cartoon Network comic 'Teen Titans Go!' (A collection of comics that focus on the animated Teen Titans rather than the original). In one issue, Mad Mod uses his fasion designer mentallaty (which was absent in the animated series) to hypnotise the citizens of Jump City.
Teen Titans Animated Series
Mad Mod, voiced by Malcom McDowell, has no superpowers of his own, but he is a master of technological trickery such as robots and holographic projectors, which he controls with a ruby-handled cane. In one circumstance he was able to use such a cane to drain the youth from someone, making them old and him young again. He has a London accent and is utterly anglophilic. Moddie, as he often calls himself, tends to view the Titans as rebellious "snots", and claims that they show no respect for their elders.
Mad Mod as depicted on Teen Titans.In "Mad Mod", his first appearance, he kidnaps the Titans and places them in a psychedelic "school", where he attempts to "teach them to behave" through hypnosis. When his initial attempts fail, he leads them on a Scooby-Doo-like chase through a Yellow Submarine-esqe maze. The Titans escape when Robin realizes that Mad Mod they are chasing is as fake as the rest of their surroundings; he thus abandons his attempts to capture him in favor of searching for flaws in the illusion. He quickly notices one - Mod's weapons have made an intriguing hole in the backdrop, which leads into the illusion's internal works. This enables him to confront the real Mad Mod in the illusion's control room - a sickly-looking old man using an advanced computer to control the entire school and the holograms of his younger self. Robin has no trouble defeating him.
In his next appearance, "Revolution", Mad Mod remakes the entire city in the image of old England by using hypno-screens to control the populace and giant illusions to change the look of the entire city to that of merry old London. He also kidnaps Robin and uses his staff to drain his youth, reducing Robin to a decrepit and helpless old man while Mad Mod becomes his young self again. The other Titans are initially prevented from reaching Mad Mod and freeing Robin by various large robots modeled after the Coldstream Guards. Eventually the Titans succeed in knocking the cane out of Mad Mod's hand, which Robin then uses to reverse its aging effects. He then breaks the cane, ending Mad Mod's rule over the city by deactivating his equipment.
He also made a cameo appearance (in his old age) in "The Lost Episode" as one of the audience in the orchestra and last seen fleeing when Punk Rocket strikes.
Mad Mod later has several small appearances as a member of the Brotherhood of Evil where he is somehow young again. He was last seen fighting in "Titans Together" where he was blown off his feet by Beast Boy in Tyrannosaurus form. He was then flash-frozen with the rest of the Brotherhood.
The character was bizarre, even by the cartoony Titans series' standards. His ability to produce illusions resulted in surreal, 60's styled landscapes, and allowed "Moddie" to appear in several different forms; even appearing stylized in the manner of God as he appeared in Monty Python and the Holy Grail, or becoming a rounded, Blue Meanie-esque creature.
