A reference for the artist's Sgt. Frog fan character, a thin human child with long, dark purple hair cut into square bangs and long sides and ends with diamond-shaped tips, green eyes, and pale skin who wears a green and red outfit and a purple heart-shaped pendant. She smiles and stands with one arm behind her back.

A reference for the artist's Sgt. Frog fan character, a thin human child with sandy blonde short hair with bangs, sides, and ends that have diamond-shaped tips, orange eyes, and peach skin who wears a blue and white outfit and a cyan raindrop-shaped pendant. She frowns with raised brows and a hand on her hip.

The two children from before as Keronians. The first is now a lavender tadpole with her human hairstyle who wears a green bandanna with a red heart charm on the knot and a purple heart-shaped badge, has a purple heart-shaped belly emblem and a heart-shaped tail and face markings, and grins widely with sparkling eyes. The girl is now a sky blue tadpole with a simplified version of her human hairstyle who wears a deep blue Keronian hat with a cyan raindrop badge on it, has a cyan raindrop-shaped belly emblem and a raindrop-shaped tail and face markings, and shouts out in panic as she examines her new form.

A reference for two of the artist's Sgt. Frog fan characters. The first is a dark teal Keronian man with one closed eye, a belly emblem that resembled an art palette, and rainbow-colored splatters on various parts of his body who wears a grayish-teal cap that vaguely resembles an artist's beret and has an art palette-shaped badge on the band who smiles and looks ahead as he swings from a large rainbow-tipped mechanicl paintbrush. The second is a moderate pink Keronian woman with wing-shaped horns, heart-shaped face markings, red eyes with dark pink eyeshadow, a belly emblem shaped like a heart with a cupid arrow stuck in it, and an off-pink, heart-shaped tail. She wears a heart-shaped, dark magenta hat with faint stitches, a dark pink heart-shaped patch in the middle, and an off-color version of her belly symbol as the badge and boots of the same color with scuffed and scratched wheels and hearts with wings on the heels as she floats.

A reference for three of the artist's Sgt. Frog fan characters. The first is a greenish-white Keronian with a belly emblem shaped like a bulb on the stalk and moderate tadpole markings who wears a black and blue Japanese chef hat with a garlic flower-shaped badge who winks and holds out a plate of curry, the second is a sky blue Keronian with a shooting star-shaped belly symbol who wears a bulky red hat with a badge shaped like a shooting star, dark magenta sunglasses, a yellow bandanna mask, and a red cape with gold buckles who stands while holding out balls of light, and the third is a peach-colored Keronian woman with off-color face markings and tail, fluffy blakc hair, and a belly emblem shaped like a microphone who wears a light green cap with a badge shaped like a microphone, a pair of headphones, and light green and black striped legwarmers.

A reference for three of the artist's Sgt. Frog fan characters. The first is a burgundy Keronian tadpole with a belly emblem shaped like an eighth note with hearts, a music note-shaped tail, and warm-colored eyes with gradient light yellow to pink makeup who wears a light orange hat with wavy, warm-colored gradient flaps, cat ear-like horns, and a badge shaped like an eighth note with hearts that smiles smugly with a hand to her face. The second is a reddish-black Keronian man with a belly emblem shaped like clashing blades who wears a blakc military hat with a light grayish-green visor that has an arrow pointing to it showing the unseen badge, which is identical to his belly emblem, and he frowns as he stands tall and adjusts his cap. The third is an elderly Keronian woman with dark gray-green skin who wears a purple cap with curved cat eat-like horns that have lighter tips, flaps shaped like snakes, and a caduceus-shaped badge, a long purple button-up cloak, and twin bags stuffed with plants who frowns with hands clasped.

A reference for two of the artist's Sgt. Frog fan characters. The first is a brown Keronian man with graident purple eyes and a purple gradient shadow over his face with a belly emblem shaped like a pie chart/fortune cookie who wears a dark red hat bandanna with a badge identical to his belly emblem and a burgundy fanny pack, and leans as he uses a toothpick to pick a fortune cookie's fortune from his mouth. The second is a dull lavender Ankeromu with a belly emblem shaped like the astrological 1198 Atlantis symbol who wears a round dark gray and pink wave cap with multiple flaps and a badge shaped like the astrological 1198 Atlantis symbol, and looks down on themself in confusion.

Keroro OC Refs

So, my Keroro SI from middle school decided to rise from the grave and sink its claws back into me, and as I was creatively spent and needed to switch things up from my usual, I decided to overhaul a bunch of Keroro OCs I made in middle school! These were drawn from May 14-18th, 2026.

In order from top-left to bottom right, we have:

Rabumi "Mimi" and Ranshouseki "Ran" Morishita (the kira-kira name is very much so intentional), the daughters of a wealthy family whose parents are constantly running around and forget they exist. One day, they get caught in the middle of some shenanigans from a pair of platoons warring to conquer Earth and are turned into Keronians. To keep the Keronian Army from finding out that their cover was blown, they take the girls and pass them off as stranded Keronian kids (aliases Rariri and Kimomo) while they try to find a way to turn them back, but gradually grow attached to the girls. After learning that they're extremely neglected and basically abandoned by their birth parents, they come to adopt Mimi and Ran as their children and effectively give up on invading Earth to raise them, and that's only the beginning of their alien adoption shenanigans!
Warrant Officer Parere, the platoon's leader and namesake. A laid-back chemist who can use his high-tech paintbrush to craft whatever sort of terrain or chemical mixture he wishes.
Private First Class Cupipi, formerly a prominent Keronian idol who was hired by the Keronian military to perform for soldiers as a morale booster, she's long since passed her prime and still yearns for her glory days.
Assassin Minini, an assassin from a family with long-standing historical ties to Keron's government and military. Their method is choice is poisoned food.
Corporal Kariri, an enigmatic man with a larger-than-life superhero persona and the power to control light.
Lance Corporal Tamimi, a voice actress who left her acting career to join the military and uses her wide vocal range to mimic just about anyone.
Recruit Clelele, an idol sensation who can manipulate people's minds with her music, literally and metaphorically. Dons a cutesy, peppy idol persona to mask her rotten and selfish true personality.
Colonel Zemomo, team leader and namesake. A strict, militant man with a strong code of honor only hampered by his long-standing rivalry with Parere.
Chief Medic Rukuku, once a highly-respected military official until a specific incident led to a demotion. She mentored Zemomo back in the day and he holds a deep respect and gratitude towards her for it, so he did her a solid and let her join.
Sergeant Major Fototo, a strict and literal-minded man who has an obsession with numbers and predictions. Always carries around a sack of fortune cookies and uses the fortunes he gets from them to plan his every move with surprising levels of accuracy.
Lance Corporal Aikaka, an amnesiac with mysterious powers that not even they are entirely sure of. The Keronian military snatched them up after some incident they don't even recall and dropped them with Zemomo out of hopes that he could awaken their inner potential and memories.
