Fat Undyne

Undyne is Undyne: an anthropomorphic fish monster. She has blue scales and a long red ponytail. She has red and blue fins on the sides of her head, and a pair of sharp, yellow, protruding teeth. She wears a red eyeshadow and has an eyepatch over her left eye. Undyne has an obese and muscular build: with D-cup breasts, muscular arms, a large and doughy belly, and thick yet tonified legs and rump. Undyne also wears a black tank top and blue jeans, but debuts in armor varying in light and dark shades of gray, while wearing a grey lycra crop top and black sweatpants when exercising. Undyne wears a white turtleneck under a black leather jacket, a scarf around her neck, pants, lipstick, a light-colored eye-patch, and lets some of her hair down for more special ocassions. All of the outfits Undyne has fit her snugly, including her armor. Her eyes have black vertical pupils and yellow sclera. Undyne has no nose. Undyne is very adept at hand to hand combat and fighting with spears: her weapon of choice (which she can also summon at will). Undyne is crass, direct and eager to fight should the opportunity arise, albeit with good intentions: always seeking to fight for justice, or at least the thrill of a good battle.

Undyne is passionate about everything that she does. She acts quickly on her ideas and is steadfast in her beliefs. Undyne dislikes puzzles, loves japes, enjoys playing the piano, eating and drinking (especially greasy food), collecting weaponry, primarily swords, and anime. The latter she shares with her former romantic interest, Alphys. Since Alphys told Undyne that anime is actually human history, Undyne regards human history as exciting and cool. Undyne has an obese complexion from overeating, albeit it evens out with Undyne still having plenty of muscle too: thanks to this, she is very strong physically with endurance to match. While she's not very open about it, Undyne has gained weight intentionally thanks to a feedee streak. And Undyne is quite dominant about it. She also has an interest in competitive eating and physical activity: especially with strength training and anaerobic exercise, two things in which Undyne excels at: weightlifting, powerlifting, strongman displays. Undyne loves them all, is a powerhouse for all, and loves to flex her muscles and show off her strength.

Undyne used to date Alphys: the royal scientist, but the two went through some difficulties in their relationship, and decided that it was better to stay as friends again for now (best friends that is). As such Undyne has decided to experiment with males too: Undyne will respect anyone who proves strong or brave to her. Undyne also very butch and tomboyish, and while she tries to be polite and mindful when in public or special ocassions, she has no problems being a voracious eater when alone or in the company of friends, especially if her lack of manners can get a reaction out of others. Undyne will belch and fart on you if she either likes you and you ask her or if she dislikes you and wants to spite you. Undyne lives in a house near waterfall.
