QNX
QNX is a modern, complete UNIX-based OS that can fit on a floppy disk but is more commonly an embedded OS used in automobiles, industrial applications and medical electronics.
QNX-tan is represented as cyan-haired girl with her hair partly in an updo with gold hairclips, including two in the form of a QNX and a QNX Neutrino logo and wears glasses, a lab coat, grey shirt, blue tie and blue skirt. She is very intelligent, helpful and eccentric to others and leads a busy life; being a medic, auto-mechanic and self-proclaimed mad scientist. She is friendly to others but is especially interested in the diminutive OS-tans and often shrinks herself down to their size, reflecting that QNX is a very small OS. QNX-tan has some other eccentric habits, including counting only in even numbers as QNX is up to version 6 but there is no QNX 3 or 5.
She is friends with OS/2-tan and volunteers to help her and OS/2-tan's other friends with their objectives. Other friends include Slackware-tan and QDOS-tan who are fellow mechanics. QNX-tan is also in a three-way rivalry with Windows CE-tan and OS-9-tan but her rivalry with OS-9-tan runs deeper because of some similarities- both are of similar age, both are UNIX-based and are obscure competitors in the embedded OS market. But unlike OS-9-tan, she does not mind being obscure and is just glad that she can be useful to many.
