— Riptor's story mode description

Riptor is a crossbreed of human and reptilian DNA, made by Ultratech and one of the playable characters featured in the original Killer Instinct.

Biography Edit

Appearance Edit

Riptor is a human/raptor hybrid, having the basic appearance of a velociraptor, but with much larger arms, humanoid muscle mass in the chest area, and broken shackles hanging from its wrists. The color of its scales changes depending on its renders and in-game appearance, ranging from being primarily orange with black stripes not unlike a tiger, to green scales around its back and tail to orange scales on the underside of its body.

In Killer Instinct (2013), Riptor's appearance was changed. Its muscle mass is distributed in a more reptilian and less humanoid manner, giving it a smaller chest and thinner arms. Its eyes are slightly larger and its head less pointed, and three flimsy spikes protrude from the back of its head. However, the biggest change by far are the cybernetic components. Metal bionics run down Riptor's back and down to the end of its tail, and its claws have been given blue energy enhancements. In place of its signature shackles are metal plates. The hexagonal patterns along its body slowly fade in and out from light blue to black, and bar codes and the UltraTech logo are tattooed in several places. Its tail can now separate into several linked units to stretch out and attack, similarly to the Snake Sword used by the character Ivy in the Soul Calibur series.

Story Edit

A product of UltraTech's DNA manipulation project. By splicing human and reptilian genes, they have created a fighting creature with animal ferocity and human intelligence.

Extended story
Another of Ultratech's miraculously realized concepts: a crossbreed of human and reptilian DNA, resulting in a creature that combines formidable intelligence with sheer brute strength. Nurtured from the egg by a dedicated Ultratech professor and her team, the beast nicknamed 'Riptor' by others has barely reached 4 years of age before it first demonstrates its full savage power in a human kill. Riptor is confused and often finds itself torn between human reasoning and predatory instincts, resorting to attack when it fails to understand the situation, as ever more people find out the hard way.

Killer Instinct (2013)Edit

Riptor is confirmed to return as the fourth character of Season Two. Riptor was brought back to life by Ultratech via cybernetic inplants, thus becoming a cybernetic Riptor.

An Ultratech Quick Start Guide

From UT Press


Congratulations! You’ve bought yourself a Riptor Unit! Your adventure has just begun!

Ultratech doesn’t always look to the future to find the solutions to military development. Sometimes, we look to the past. So it was with the Riptor project. My mentor, the brilliant genetic engineer Dr. Erin Gupte, believed in a beautiful dream: a ruthless adaptable predator that could rely on its own victims for sustainment, and could maneuver and infiltrate areas where the Fulgore line would never be able to function. [UTM: Can we change the word “victims” to “rivals” or something less pejorative? It makes the Ripter units seem like bullies.]

It is a living and breathing example of American ingenuity!

Dr. Gupte’s first efforts at de-extinction, however, were failures, producing dangerous and uncontrollable animals. But when Dr. Gupte began using her own mind as a training tool for her new creations, simulating upbringing through directed thoughts, a breakthrough happened. She guided the creatures into understanding that there was a place for family and the idea of a pack, “from egg to engagement.” [UTM: Perfect! This makes Gupte sound way less unhinged than the previous version.]

Dr. Gupte’s mind-sync with the Riptors had its consequences, however. Her emotional state became unbalanced, and eventually Gupte’s Riptor units turned on her in a tragic act of feral violence. Like many early explorers she had stepped too far too fast. [UTM: This contradicts UT vision. It should instead be framed that she “boldly stepped beyond the bounds of caution, seeking knowledge to further humanities understanding of blah blah blah.” Let’s make lemonade here. Frame this as she died in pursuit of knowledge, blah blah, etc. But that’s the fate of so many heroes.]

Several years have passed since Dr. Gupte left us, but we have not been idle. The RDG (Riptor Development Group) is stronger than ever, thanks to the hard work and dedication of thousands of scientists and technicians, as well as over a billion dollars in R&D. The units themselves have been perfected, and are nearly ready to be deployed by private military contractors. [UTM: No! They ARE ready and UT is selling them to private companies! See recent sales report and insert rounded up # of units here.]

Good luck! And go Ultratech!

–Dr. Stephanie Hastings, CEO, Riptor Development Group

[UTL: Hastings employment will be terminated next week in the reorg. Make sure she signs a release for this introduction or attribute it to her successor.]

Quick Start Guide

Chapter 1: Unboxing

[UTL: This entire chapter has been deleted and has to be rewritten in accordance with the Ultratech Safety and Handling department after initial user testing of unboxing process caused 3 deaths and 4.5 dismemberments.]

Chapter 2: Care and Feeding

You’ve probably already realized that your Riptor unit eats a lot! This hungry lady consumes about 5% of her body weight daily (up to 50 lbs of meat). That’s a lot of live goats—the preferred Riptor diet. [UTM: Include official link in e-book version to online page for the “Goats On Time, Anytime” Ultratech livestock purchase form.] The most important thing to keep in mind at feeding times are the 3 R’s: Respect, Risk and Reaction Time. Let’s start with the first one.

Respect: Your Riptor has human DNA, so she’s very smart. Always speak to her in a respectful manner because she most likely knows exactly what you’re talking about, even though she does not have the capacity to respond. Refrain from Jurassic Park jokes. [UTM: Can you please change Jurrasic Park reference to something more generic like “Refrain from genetically enhanced dinosaur jokes.”] This will only confuse the Riptor, and as you learned from Chapter 3 “A confused Riptor is an angry Riptor.”

Risk: There is inherent risk at feeding time. The Riptor will be incredibly excited about the prospect of eating. Their internal clocks are highly accurate, and they don’t like being hungry. It makes them edgy and irritable. Never look directly into your Riptor unit’s eyes at mealtimes. Their gaze is hypnotizing and this leaves you open to attack. It’s always best to wear your Ultrafyber™ Feeding Gauntlets[UTM: Nice! The Quick Start Guide needs more cross-promotion of UT products like this.] when pushing goats into the armored feeding bins. Riptors have been known to rip through the metal slot bars in a frenzy to get at their dinner.

Reaction Time: All Riptor owners are advised to partake in physical training that increases fast-twitch muscle responses. A Riptor’s bio-enhanced tail can whip at 5 meters per second. That’s as fast as a Black Mamba strike. While the tail isn’t poisonous, the Riptor’s claw tips are teeming with microbes, [UTL: They’re focused plasma, actually. Cauterizes and sterilizes! A benefit!] and the slightest scratch can cause infections similar to flesh-eating bacteria. So stay back and always be on your toes. Or you might get them ripped off your limbs. [UTL: This entire section needs to be cut. Sets UT up for a major lawsuit and creates an indelible and negative image of maimed Riptor owners hopping around on one foot. We’ve already had enough trouble with the Fulgore Mark 03 Field Manual-L class action suit fiasco.]

RIPTOID (Riptor Factoid) [UTL: Have we copyrighted the word “Riptoid” yet?] [UTM: Yes!]

Once your Riptor unit has been satiated by her meal, it’s an excellent opportunity for enhancing the human/dino pack bond. The segments where the Riptor’s tail bionics are adhered need to be scrubbed regularly, and the best way to do this is with a stiff metal brush. The animal’s hide is reinforced with tiny bones called osteoderms, and these serve as a kind of organic chain-mail, making it very difficult to clean. [UTL: No, no, no! We never highlight anything that might lead to a return of the product or a mass recall. Emphasize the fun of scrubbing the Riptor’s tailparts…“It’s just like grooming a pony, blah blah, etc.”]

The Riptor might show her appreciation for this act by butting you with her head while making a low growling sound. Do not be alarmed! This is the Riptor’s version of a purr. You know that a Riptor has truly bonded with you when they regurgitate their gastric pellet at your feet. [UTL: Please remove the photo of the gastric pellet. It’s unappealing and all Riptor waste has tested as a biohazard and should not be documented. Owner should be directed to Chapter 10: Cleanup Time! and a direct reference to the UT Riptor-Box/Enhanced Litter system.] [UTM: Ditto what legal said.]

[Note: the following chapters are currently being rewritten and will be available for copyedit soon.]

During an Ultra Combo, a military base in the background launches multiple missiles at the stages, destroying many evidence that is left at the crash site.

Combo Trait - Fire and Tail Linkers: After an auto-double, Riptor can follow up with a three hit flame or tail attack by simply pressing Hard Punch or Hard Kick.

Ultra Combo: 31 Hits

Trivia: Her theme is basically her remixed classic theme, "Rumble".

  • Riptor did not appear in Killer Instinct 2. In TJ Combo's character profile, he was said to have had a "decisive victory over Riptor", implying he had put an end to Riptor once and for all in the previous tournament.
  • Though Riptor's actual gender has never been confirmed and it was left ambiguous to the fans, it is very likely that Riptor is a female due to having laid eggs during the tournament as shown in Riptor's ending. How Riptor got itself impregnated is unknown.
    • It is known that female reptiles can produce an egg asexually, though the egg produced is a genetic copy of the mother.
      • Iron Galaxy, developers of Killer Instinct Season 2, refer to Riptor as a female.
  • The original Riptor model has a hidden cobra hood which it only unfurls when it prepares one of its three No Mercy-moves.
