Slugs are the magical creatures that are the main focus of SlugTerra, that transform into more powerful versions of themselves when they hit the speed of 100 miles per hour. There are currently 48 known breeds of Slugs (not including ghouled slug) that fall into 12 different elements. Each breed of Slug has its own unique powers. While many of those breeds are used for battling, some, like the Bubbaleone, can also be used for household chores. Younger children tend to keep Slugs as pets, often bonding more closely with their Slugs than Slugslingers do.

Due to their battle capabilities, Slingers often see their Slugs as a little more than ammo. No longer a childhood pet, many Slingers don't think twice about trading or selling their Slugs. In some SlugSlinging competitions, the prize for winning a duel is being allowed to take a Slug from the losing Slinger's arsenal. As a result, slugs have little choice in who their owner is, and can change hands frequently.

When these slugs are fired with the help of Blasters, they reach a speed of 100 miles per hour and transform into a stronger form called Velocimorph/Battle Form which can be highly destructive. Once they are fired, they can only be re-used if their Slingers are fast in picking them up and reloading, otherwise they will return to one's hideout if one is friendly to them. All Slugslingers have to expand their arsenal and for that they use certain techniques like only talking or using special slug collecting devices. Slugs need be fed regularly so that they remain healthy, and baby slugs need extra special care to help them mature.

If experienced enough, slugs can evolve into a more powerful form called Megamorph when they are shot at 200 miles per hour, else, it will get thrown off by the speed. By using an accelerator in the blaster, you can make a slug mega morph more easily. They are kept in special cylinder-shaped cases called slug containers. Blasters have three parts, the base, barrel and space for reloading in which slugs are fitted and then fired by fusing energy of slugs and blaster.

Acquiring Slugs

There are numerous ways for Slingers to gain a new Slug for their arsenal. The first way is to go out and catch a Slug in the wild. Wild Slugs can be found nearly everywhere in SlugTerra, although some Slugs are very rare and not every Slug can be found in every cavern. Some Slugs, like the Forgesmelter, are rare not only due to their lower population numbers in the wild, but due to the difficultly of navigating through the dangerous volcanic cavern they call home.

There are several ways to catch a Slug in the wild. The first is to use a Sonic Snare, a device that uses sound waves to temporarily stun and weaken a Slug, making it easier to catch. This method can be risky, especially when dealing with a large group of Slugs, because the Snare can cause a Slug to weaken to the point where it loses its grip and falls. If the Slug falls from high enough up, it will hit velocity and transform. While not a major problem with one Slug or even just a few, enough Slugs transforming at once can have a devastating effect as seen in The Slugout.

Safer methods, though admittedly ones with lower odds of success, include the use of Slug Spray, Slug Reels, Slug Paper, Nets and the Arachnet slug. The best way is to talk to slugs, as demonstrated in The World Beneath Our Feet Part 1 and The Slugout.

Slugs can also be bought and traded. In some places, Slugs are used as currency in place of Gold, with a Slug's experience determining its value. Some Slugs, due to either rarity or a high level of experience, can be very valuable.



Slugs are small, bipedal creatures that are often brightly coloured.  Their colouration or markings often offer a hint as to a Slug breed's element, although this is not always the case.

Most Slugs can survive and breath underwater without the need to surface, although almost all species of Slug need Torpedo Shells in order to reach velocity underwater. Additionally, fire-type attacks don't work under water, making breeds such as the Infurnus highly vulnerable.

A Baby Slug is called a Sluglings/or just Fingerling.


A velocimorph is the Slug's form upon hitting 100 mph, transforming into a larger, more powerful creature. In almost all cases, the velocimorph bears a reasonable likeness to the Slug's protoform appearance. The Lavalynx is the most notable exception to this rule. Flopper Slugs are the only known Slugs to not transform upon reaching velocity.

Upon reaching 200mph, a Slug will obtain a mega velocimorph, which slightly changes the features of the individual Slug's protoform as well as their colour markings. While the changes to the Slug's protoform are permanent, the Slug maintains its breed's standard velocimorph whenever fired at 100mph, only returning to its Mega Morph form when fired at 200 mph or above. With the altered protoform, a Slug will glow when it reaches 100 mph without being fired, acting as a speedometer to let their Slinger know when enough speed has been achieved to reach Mega Morph form.

Slugs that reach a certain level of power can become a special guardian slug.

The 5 Elementals are ancient slugs of great power, and said to be the forebearers of all slugs found in Slugterra today.


Main article: Slug Energy

Slugs are combat-capable and many Slugs enjoy dueling or, at least, transforming at velocity. In ages past, in the time before blastersSlugs used their environment in order to gain enough speed to transform. Occasionally, some Slugs still use their surroundings for their advantage in battle, especially when their Slinger is unable to get them to velocity, due to problems with his or her blaster or incapacitation.

Transforming at velocity, more so than actually battling, is how a Slug gains experience. For Slugs, experience comes in the way of increased Slug Energy. Since blasters are powered by Slug energy, more experienced Slugs make for more powerful shots.  If a Slug gets too powerful, it's energy can overload a blaster's fusion core, damaging the blaster. Once a Slug gains experience, it never loses its increased levels of Slug energy, even if it goes a long time without reaching velocity.

As Slugs gain more experience, they also gain new abilities.  Often, these powers are related to combat, but some breeds, like the Fandango, fill more supportive rolls.  The most powerful of Slugs can become Guardian Slugs, a position that almost all Slugs wish to achieve.

Slug food

Slugs can eat almost anything, but too much "people food" isn't good for them. A Healthy Slug requires a balanced diet, which can be achieved by giving them slug food.


As seen in the Slugisode:Fun Facts About Slugs, it shows that slugs are usually quite friendly to other slugs, regardless of species, sleep early, and have well table manners.

Slugs, through dark science, can be corrupted and are turned into monstrous beasts called Ghoul Slugs. They are only distributed by Dr. Blakk. These slugs are unpredictable, somewhat unstable, vicious, and mischievous.

Slugs have been shown to have human level intelligence and even posses their own hidden socitey of sorts.

Artificial Slugs can also be built, able to hold a database of all Slug (excluding the rare Enigmo Slug) powers and counter them in battle.
