Carly (G1)

Carly is a human character from Generation 1.
Carly is a human ally of the Autobots and wife to Spike Witwicky. She attended MIT and has a gift for electronics. She eventually gave birth to Daniel and settled down.
Fiction
US cartoon
Carly first met Spike and Bumblebee at a video arcade. Although Spike was considerably younger than she was (Carly was attending MIT while Spike still wasn't even old-enough to drive), she became immediately intrigued by him and his friendship with the Autobots. After befriending crusty old Ironhide, and helping save the Autobots from the threat of the Immobilizer, she was accepted as their new human buddy.
Carly and Spike later went on a dangerous mission to Cybertron to retrieve more Cybertonium, an element the Autobots needed to survive. Carly's technical know-how once again proved useful as she, Spike and the Dinobots outwitted Shockwave and stole some Cybertonium.
Later, in the year 2006, she was seen as an Earth ambassador to Cybertron along with her now-husband, Spike. The pair even cursed the fiction with their offspring, Daniel.
Scramble City OVA
(Note: the events of the Japanese-exclusive Scramble City OVA take place between the second season of the US television series and Transformers: the Movie.)
Carly can be seen working with Spike, Sparkplug and Chip on Autobot City.
Headmasters anime
Apparently, doing anything constructive with her degree from MIT wasn't a priority for Carly, as she became strictly a doting housewife by 2011. Her new duties included: serving coffee, worrying about things, and getting injured so that men could rescue her.
However, it's nothing to get upset about because, as we all know, Japan has the utmost respect for women.
Headmasters manga
Carly appeared in the last issue of the manga, strolling the beach with her family and Autobot friends shortly after the defeat of Mega Zarak. After Soundblaster attacked, Carly was taken hostage by Slugfest and Overkill until she was rescued by Daniel.
Dreamwave comics
Carly appeared as Spike's wife in two issues.
