In the1980s, Rankin/Bass Entertainment had a lot going on. They’d been creating hit animated movies likeRudolph the Red-Nosed Reindeer(1964)andThe Hobbit(1997)but now they were trying to create a series of three animal-hero-based syndicated cartoons. The first, and most well-known, wasThunderCats, then cameSilverHawks. These two shows were much loved by childrenin the mid-1980s.
However, the final show that rounded out the three wasTigerSharks. It followed a similar formula, tried it just a bit differently, and missed the boat. It’s a shame because the show had great potential and never really made it to the same level as its sibling shows. But what wasTigerSharks,and why have you (probably) never heard of it?

The Big Three
Let’s break down the fact that these Rankin/Bass shows were not complete cookie-cutter ideas but were 100% from the same place. They each followed a specific ecosystem, namely land, space, and oceans, and a species-specific group of heroes: cats, birds, and marine mammals.
ThunderCatscame firstand was wildly successful. The basic premise was that a group of human-cat hybrids must leave their home planet of Thundera only to arrive at a new planet where they fight against an ancient evil being named Mumm-ra (a scary mummy villain who turns into a powerful monster under specific circumstances). Their tagline was “Thundercats are loose!”

The following year saw the release ofSilverHawks. This show followed a group of space adventurers who had been physically altered with robotic parts so that they could survive in space. They protect the galaxy from MonStar (a scary crime boss who turns into a powerful monster under specific circumstances).Their tagline was"Partly metal, partly real!"
The third series to come out wasTigerSharks. It deviated from the typical plan of the first two series in its plot, which seems like it could have helped, but instead, it made it the outlier. Its tagline was “Look for a spaceship with a sail!” Not quite the punch of the first two.

Here are the most unsettling evildoers from the decade that spawned ThunderCats, Inspector Gadget, and He-Man and the Masters of the Universe.
The Thundercats' Formula
Often referred to as “the wet thundercats” or “thunderfish” by those who remember the show,TigerSharkstook the idea of a group of human-like aliens who are on a research mission to a planet called Water-O that is almost entirely covered in oceans. Their spaceship, the SARK, is able to function as a boat and submarine and features a special transformation tank into which the characters would leap to morph into sea-going versions of themselves. Each one had its own new, cool form based on a specific sea creature.
Let’s run down some of these characters. It’s important to remember one thing about “the formula” that was consistent throughout the three shows. There was always a strong male leader, one female character, and at least one or two child heroes.
These ’80s Cartoons Should Get A Movie
Adaptations of books and comics are common, so why not cartoons from the 1980s to reinstate the nostalgia?
The other thing to remember about “the formula” is that the team needed a somehow MORE animal sidekick. InThunderCatsit was Snarf,SilverHawkshad TallyHawk, and inTigerSharksit was Gupp, a dog who turned into a seal.
The bad guys were a little different. They were not simply one group with one scary leader. Instead, there were two bad guys with their own groups that often worked together while undermining the other. One of these was T-Ray, who led the Mantannas. They are a sea-going race that must remain underwater or wear special suits to survive on land. They want to conquer Water-O for themselves. The other character is Captain Bizzarly who runs a ship of pirates who hate the water. Bizarrely was once the main villain of the planet but was frozen in ice by the inhabitants before being released by T-Ray in the hopes that they could team up.
TheTigerSharkswere constantly at odds with these groups and fought for the Waterians in an effort to keep the planet safe while learning about the undersea life that surrounded them.
So Why Didn’t It Work?
One of the main things that ’80s children’s television was known for was tie-ins. Many shows, such asHe-ManandTransformerswere created after the toys themselves had been made. The shows were glorified commercials. In the case of these shows, the show came first, and the toys came second. However,ThunderCatssaturated the market with their characters and formula. TheSilverHawkswere able to cash in on children’s love of space and all things laser-gun-related. However, the idea of underwater heroes didn’t seem all that fantastic to viewers. This meant that although they were able to survive two seasons, they couldn’t hold enough attention on their own.
It should also be noted thatTigerSharkswas not a standalone show, but it was the only one to feature as a cornerstone of the Rankin/BassThe Comic Strip.This also featuredStreet Frogs,The Mini-Monsters, andKarate Kat. These shows aired together, and it was therefore quite easy to miss one or the other.
TigerSharkswould probably not have been successful even if it was the first show of the three. It relied onan underwater gimmickand lacked much of the original flavor of the first two shows. Had ThunderCats come last, at least it would have had more interesting plots and more compelling characters for kids to relate to.TigerSharksgave it a try, but it didn’t have the power to leave the same mark on the public consciousness.Currently unavailable to stream.
