This article is about Dr. Gross's creations. You may be looking for the category for hybrids.

Hybrid Animals are creatures that Dr. Gross had created using two distinct species of animals and monsters. In some cases, such as the diamond Komodo dragon, it is one species of organism combined with a mineral. In all cases, the hybrid animals possess bionic upgrades, and this allows Dr. Gross to control them. They make another appearance in "Reboot," but only the unnamed eel-dragon, referred to as a "giant electro-eel" by Finn, makes an appearance in the episode. In "Helpers," Dr. Gross is seen working on the first hybrid animals, which Minerva decries as "strange and dangerous" work.

Known hybrids[]

Diamond Komodo dragon[]

Diamond Komodo Dragon

The diamond Komodo dragon is the first hybrid that's walked passed by the group. It isn't given much attention by the characters, nor do the camera angles pander to it. Once it's transformed, its eyes turn static, identically to the other hybrids, and becomes bipedal with both thick upper and lower appendages.


Fly Flan

Given in the name, the fly-flan is a combination of a fly and a dessert. They are often seen with prominent rear-ends, which is a common gag in Adventure Time. The fly-flan isn't seen to transform in "Preboot" but is found outside after everyone escapes the vessel.



The shark-mouse is stated to be "a shark that breathes air." Despite the juxtaposition, it is still seen living inside an aquarium, although this could be so that it can move around without it transforming limbs. It could also be amphibious but to an extent, being able to breathe through gills or lungs depending on the situation. Its entire body is based on the shark, while its face is from the mouse. When transformed it contains powerful upper body appendages, but disproportional legs.



Chicken-bees' bodies appear to be a chicken with bee-like features. Despite being referred to as a chicken-bee from the concept art, Dr. Gross claims this hybrid has wasp wings. When it is transformed, the borders between the yellow and black striped pattern sprout buzz-saws. Jake seems to admire chicken-bees; he pretended to snap a picture of it.



Tiffany provides the name for this hybrid, and this is the only hybrid that evidently possesses sapience. Similar to chipmunks seen in other episodes such as "Bun Bun," he possesses the ability to speak English, albeit with a relatively deeper voice. He attempts to warn Finn and Jake through a dance but is unsuccessful in communicating his intended message. Scorp-munks transform with robotic claws that extend from under their feet and teeth that become extremely sharp.



Wolf-lards are Dr. Gross's assistants who were called upon when she was going to insert an implant in Finn, Jake, and Susan. According to Tiffany, they have the high endurance of a Sea Lard, combined with the blood-thirsty killer instincts of a Sea Lard. When under Dr. Gross's control, they do not appear to undergo any noticeable morphological change with the exception of their eyes.



The gator-squid is seen briefly, and is not given a whole lot of screen time. It may possess the same amphibious abilities that the shark-mouse does. When transformed, the ends of each appendage grow three bionic fingers, presumably to aid its movement across land. Another transformation the gator-squid endures is its jaw extending by the means of a hydraulic.



The spider-turtle is given no special attention in its debut. It can be seen when Dr. Gross leads Finn, Jake, and Susan into her menagerie, and when seen, appears to leave its head exposed with all appendages inside its shell. This hybrid is not seen anywhere outside after the vessel explodes.

Clock Bear[]

Unamed Hybird Animal(3)

This hybrid is referred to as "a guy that knows what time it is," who is also one of Gross's best. He makes his first appearance in the episode "Hoots," although this was actually inside a dream Finn was experiencing. When he transforms, he increases in size taking on the appearance of what a typical grizzly bear looks like. He later plays a major role in "The First Investigation."


Unamed Hybrid Animals

Not much is seen from this apple hybrid in comparison to the other hybrid animals seen in "Preboot." This hybrid is shaped as an apple, with its other counterpart unspecified. It is not seen to transform, nor is it seen outside the vessel when the others escape.

Unnamed hybrids[]

Electric eel-dragon[]

A very notable hybrid seen in both "Preboot" and "Reboot." This hybrid goes without an official name, neither being named within the episode, or having its name given through concept art. However, this hybrid is referred to as a "giant electric eel," by Dr. Gross, and as a "giant electro-eel" by Finn. It is a gargantuan creature; its ability to fly and send electric currents make it very formidable. This hybrid does not undergo any visible transformation.


S8e13 Rat-reptile

Rat-reptiles are unnamed hybrids seen in the Islands mini-series episode "Helpers." They may have been a pest on Hub Island, evidenced by their ubiquity and lack of confinement. The anterior portion of this hybrid contains the rat half, while the posterior portion is of a reptile, most likely of a lizard. One rat-reptile died on the window after being poked with a pen by Dr. Minerva Campbell. Another one is seen pushing a vial off a table, accidentally releasing the virus that consequently led to Minerva uploading herself.


S8e13 Dog-fish hybrid

Dog-fish are one of the first hybrid animals by Dr. Gross, along with the rat-reptiles. Like the other pioneer hybrid animal, the dog-fish go without an official name or title. This specimen features a dog on the anterior side, and a fish on the posterior side. One dog-fish is given an injection that causes its ears to fall off.


  • The fly-flan isn't seen to transform nor chase after Susan, yet somehow makes it outside.
  • It is unknown how the electric eel-dragon escaped the vessel, as there is no exit large enough for him to get out of.
  • Appblop was an entry for the 2013 CN Character Contest.[1]
