Tantrum

Tantrum is the Simplicitrix/Stabilized Simplicitrix's DNA sample of a Serenum Modicum Draco from the planet Numquam Deesset Pulsum, orbiting the planet of Regiis-Reptilium. She is a free-use alien originally made by WTB.
==Appearance==
Tantrum is a feminine reptilian humanoid with draconic features, mostly covered in smooth dark navy blue scales, with cyan scales on her jaw, neck, stomach, claws, and down the underside of her long tail, and triangular stripes running down the top of her tail and the sides of her thighs. Tantrum has a very short snout with jagged lips, blushing cheeks, large vibrant eyes, pale red hair being tied upwards into a scruffy ponytail by a bright red band, a bright blue flower with golden petals rooted into the very tip of her tail, and both her thin arms and digitigrade legs each ending with three claws. Her outfit consists of a bright red top and loincloth around her waist, both striped with black, along with a pair of diamond-shaped earrings on each side of her head.
When transforming into her berserker form, Tantrum's features become crooked and jagged, with veins protruding and bulging in random places, eyes becoming wider and bloodshot, hair becoming bristled and matted, and both her ponytail and tail flower igniting and spewing out torrents of rainbow-colored flames. While lacking horns, teeth, and visible nostrils in her base form, Tantrum fully develops them in her berserker form.
Tantrum wears the Simplicitrix on her left shoulder.
==Personality==
Tantrum embodies the very essence of joy, being so incredibly exuberant and cheerful so much she exudes childlike naivety and curiosity, on top of having the mannerisms of a slapstick cartoon character, literally springing off surfaces and bouncing all over the place. Although playful and affectionate towards anyone she meets, Tantrum cannot bare the presence of any sort of negativity around her, becoming so genuinely ill her emotions will wildly fluctuate between bouts of sadness, to unbridled rage, to overwhelming paranoia, to near-total catatonic.
However, should her emotional abilities become dysfunctional, Tantrum will become increasingly unhinged the more she becomes saturated with violence, developing sporadic tendencies and becoming susceptible towards miniscule outbursts as her resolve breaks down. With the complete transition into her berserker form, she will become the exact opposite of her original self, thriving off savagery and radiating pure malevolence towards everything around her, with the more violence she absorbs, the more and more her rage escalates, deteriorating her sanity until she becomes nothing more than a mindless beast.
==Powers==
*Tantrum can convert ambient violence into pure unadulterated kindness, which although appears as if her diminutive size and cuddly appearance instantly flips a primitive switch in the minds of others, making others feel nothing but intense joy, she instead forcefully absorbs and purifies it into her aura of pure positivity, thus beneficially influencing her environment around her, such as promoting plant growth, cellular regeneration, social interactions, and even her own state of mind, making herself happier and happier the more violence she purifies.
*Should Tantrum absorb and store too much violence at once, such as from suffering grievous injuries as the result of others inflicting harm onto her, becoming overwhelmed with too much violence to convert entirely, or losing her positive mentality out of sheer pessimism altogether, her powers will go haywire and implode on themselves, driving her insane upon being deprived of her signature euphoria and turning her hellbent on resolving all violence through the most extreme measures, thus twisting her into an animalistic rage of absolute animosity. 
**While in her berserker form, Tantrum develops immense size, strength, and speed that chaotically increases the more violence that she absorbs, no longer converting it but indefinitely fueling herself, while her scales become thicker and densely armored, exponentially heightening her durability and endurance, and her senses become sharper and much more acute. Her body temperature, heart rate, and blood pressure all consecutively rise faster and faster the larger she becomes, causing any secreted body fluids to be at boiling temperatures, and her muscles to emanate out clouds of scolding hot steam.
**While in her berserker form, Tantrum's regenerative factor becomes accelerated and nearly instantaneous, which although imperfect because of her unstable growth spurts, more so growing new tissue onto damaged body parts rather than restoring damage, its potency further increases the more intense her injuries become because of their ultraviolent nature. The more gruesome her wounds are, the more she mutates in response, eventually causing jagged bone spires and engorged musculature to rupture through her scales.
**While in her berserker form, Tantrum can concentrate her overabundant energy into her teeth and claws to rapidly vibrate them back and forth in place, which that, combined with microscopic ridges that can slice into objects, give them shredding properties similar to the cutter teeth of chainsaw blades, greatly increasing her slashing and biting power. Their vibrational strength and speed increases the more powerful she becomes, making them able to effortlessly shear straight through near-indestructible materials.
*Tantrum can breathe out multicolored plumes of burning neon plasma, able to melt through most metals and grow hotter the stronger her berserker form becomes, deriving from her symbiotic tail flower absorbing harmless forms of radiation, such as ultraviolet rays and microwaves, and metabolizing them to create more energy and fuel her neon plasma breath. The state of the flower externally displays her innermost feelings, blooming with happiness and wilting with sadness, and can regrow if ever plucked off by an outside force.
*While in her base form, Tantrum has enhanced agility, although in short bursts that leave behind rainbow-colored trails of neon plasma, stamina, jumping, climbing, and tracking, on top of her sharp claws, prehensile tail, and natural resistance towards extreme temperatures, both hot and cold.
==Weaknesses==
*Tantrum's base form has mediocre physical strength, and her enhanced agility only works in short bursts.
*Tantrum's base form and her happy-go-lucky personality can be exploited depending on the circumstances, due to her childlike obliviousness and gullibility, while on the other hand, her berserker form and its sheer ultraviolence is a threat to everyone and anyone around her.
*While in her berserker form, Tantrum's teeth and claws can be knocked out and even shattered to negate their vibrational effects, although she can easily regenerate and grow back new ones in their places, possibly much larger and stronger than before.
*While in her berserker form, Tantrum's neon plasma breath can overwhelm her temperature resistance should it become too intense, severely burning her and risking explosive results should her jaws be sealed shut during the process, which although she'd only become more powerful because of the violent nature of her inflicted injuries, the damage would still persist unless her regeneration can try and heal over it.
*While in her berserker form, Tantrum is the most vulnerable against those capable of emotion manipulation, doing so through permanently keeping her in a constant state of euphoria, preventing her from entering her berserker form altogether, or forcefully reverting her from it through removing her rage, thereby calming her and causing her to shrink back down, such as from Cruxamicientes-Curriculos, Cognitisapiens, and Hydrocessabit Faveochaeris.
**In the case of the Cruxamicientes-Curriculos, Dragon Queen's species, Tantrum's reversion is always guaranteed under ordinary circumstances, as their hormone manipulation can fully take control over the growth hormones that trigger and fuel her berserker transformation.
==Etymology==
*Tantrum's name refers to the phrase "temper tantrum," referring to her berserker form from becoming overwhelmed by pure violence.
*Tantrum's species name is the Latin translation of "sunny little dragon," not only referencing her enthusiastic attitude, draconic appearance, and the fact she drives sustenance from sunlight to fuel her neon plasma breath, but one of the nicknames of Yang Xiao Long from RWBY.
*Tantrum's planet name is the Latin translation of "never miss a beat," referencing the repeated catchphrase of Neon Katt from RWBY.
==Trivia==
*Tantrum's berserker form was drawn by Shark.
*Tantrum pays homage to Yang Xiao Long and Neon Katt from RWBY, with the former seen with Tantrum's ignited ponytail referencing Yang's trademark fury and the visual effects of her Semblance, Burn, and the latter seen with the rainbow colors of her neon plasma, the fact she can leave behind rainbow trails, and her color scheme coming from the outfit of her Atlas appearance in Volume 7-8.
*Tantrum's cutesy appearance and mannerisms were based off Pinkie Pie from My Little Pony: Friendship is Magic and Princess Unikitty from The Lego Movie, even sharing the latter's issues with rage, affinity for rainbows, and hypothetical voice actor, while the sheer adaptability of her berserker form, alongside her boiling body fluids, were unintentionally inspired by Shin Godzilla.
*Like Breath Penalty, Amphiptheater, Stomache, Skellerina, Kitty Splitter, MaTrix, Capturrific, Liesight, Dovahskiin, KobOld Fashioned, Titty Titty Bang Bang, Murphy's Maw, Kanjiration, Headstrong, Pretzelcoatl, Liczard, Thunder Thighs, Cindurance, Defenderm, Draguardian Angel, Draconomaly, and Primalfunction, Tantrum comes from the same planet as Dragon Queen, mainly originating from one of their planet's moons, explaining the similarities in design, abilities, and the fact all of them are exclusively female due to their genetic similarities. 
**However, while Dragon Queen is a humanoid dragon, Tantrum is more of a humanoid drake, evident by her small stature, complete lack of wings, and the extremely animalistic nature she adopts within her berserker form, as drakes are considered more as giant lizards despite being synonymous with proper dragons.
