In Akintale, Gasters are a species of monster that are visually the same as skeletons. The only connection to W.D. Gaster here is that he is one.
The original 8
The 8 original Gasters were created by an ancestor of Asgore, Pegaarm, and were each named after a type of font (rather than a font themselves) and given a colour. Like Boss Monsters, Gasters only age when they have children to replace them. Not every attempt was successful, Gasters that were deemed failures were dusted when a working one replaced them, these were the 8 that outlived their creator.
In age order:
"Your judgement looms."
"Don't be afraid, death knocks at all our doors eventually."
"Come, sit and we'll talk about what is to come."
"Run if you want, it changes nothing!"
"Enjoy what little you have left rather than waste time praying for more..."
"It's a shame really, not your impending death but your refusal to accept it."
"Are you sure you wouldn't prefer to catch your breath?"
"Let's see if you've done enough to change your fate..."
The Gaster of change judges those who have tried to redeem themselves somehow or beings that fell from grace. This means they sometimes share a judgment with Cal. Mimicry has something like a split personality. Both personalities are aware of what happens regardless if they are in control or not. These two personalities are known as Mimi and Cry.
- Mimi is in control when judging a Redemption. She dedicated to her job but is easily distracted. She is however very fast, both physically and mentally meaning she will work he way back round to the topic at hand regardless of how side tracked she gets.
- Cry judges the Fallen and is more reserved. She tends to walk rather than run and brings her prey to her rather than chase it. She is calm and serious. Despite her name, she is never seen crying.
- Despite Dingbat and Mimicry being the same age, Mimi is treated as the youngest but Cry is treated as though they are older than Bat.
- They willing share everything (including their font and husband) and never fight to the point where people question if they actually are two different beings or not.
Even though they were created by the same people and some times at the exact same time, they share no EDC (Enchanted Dust Code, monster version of DNA) other than that required to make them genetically compatible to preduce offspring.
Scry and Cal are considered twins even though they aren't any more related than the other Gasters because they were created at the same time.
Mimicry and Bat are also considered twins for the same reason.
Ro and B are treated as siblings by the other Gasters but they don't threat eachother as such. Their creator intended for them to be a couple.
Des was originally created to replace Ty as his left eye never worked. Ro then pointed out that seeing the sins of newborns was somewhat pointless and Ty was spared and allowed to continue his work as a Gaster.
The 2nd Generation
Script (French Script) + Blackletter (SW Gothe) = Freestyle script(f), Cardinal(m), Cloister Black(m), Segeo script(f)
Roman (Times new roman) + Typewriter (hammer keys) = Fragment Core(f), Bookman Old Style(m)
Mimicry (FakeHieroglyphics) + Calligraphy (the king and queen) = Porcelain(f), Chinese calligraphy(f), Hurricane(m)
Display (Liquid Crystal) + Dingbat (SW Astro) = Hacked CRT(m), Arcade Interlaced(f), AR Hermann(m),
As the roles of the Gasters' children overlap with one another, the oldest gets the role. Others become backup Gasters for when/if the oldest can't do the job.
The 3rd Generation
Freestyle script + Bookman Old Style = Arial(f), Helvetica(f), Calibri(m), Futura(f)
Segeo script + Hacked CRT = ?
Fragment Core + Hurricane = ?
Porcelain + Cardinal = ?
Chinese calligraphy + AR Hermann = Wingding
Arcade Interlaced + Cloister Black = ?
Freestyle, Futura & Wingding were the only ones to survive the war.
At this point, all roles have condensed down into Sans.
