Canon character from Transformers: Robots in Disguise (the IDW continuity, in particular).

To quote her TF Wiki article (I.E. I didn't write this):

Nautica's upbeat demeanor conceals the mind of a brilliant intellectual. Whether she's tackling quantum mechanics with the help of her trusty wrench or negotiating a ceasefire between warring alien races, she brings an impressive command of engineering, literature, cartography, moral philosophy, and linguistics to the table, and this wealth of knowledge makes an invaluable asset on just about any given adventure.

Despite this wealth of knowledge, Nautica can be a bit socially clueless and has sometimes struggled with the feeling that she doesn't always fit in with her fellow Autobots. Indeed, she's often happiest when she's away from her homeworld and exploring the wider galaxy, where she can put her submarine alternate mode and its limited spaceflight capabilities to better use.
