Transwarp

Transwarp is the general name for the technology that sandwiched between the infinite universal streams that make up the multiverse, there is an expanse of nothingness that acts as a buffer between dimensions. This interdimensional space has many names including unspace, overspace, underspace, infraspace, subspace, and foldspace—but it is most famously known as transwarp space, since that name is often used for much of the technology built around exploiting its properties.

Transwarp space—or just "transwarp", and also spelled "Transwarp" or "TransWarp"—has become an integral component of many well-known Cybertronian technologies, even if its creators do not always understand the specifics, or even the fact that they are utilizing transwarp at all. Subspace radio allows broadcasts to span galaxies by beaming them through transwarp space, while personalized subspace storage pockets give Transformers the ability to store their weapons, and in some cases shunt their mass, outside their dimension. The most famous use is surely the space bridge, which allows a traveller to traverse vast intergalactic distances almost instantaneously by means of a "short-cut" through transwarp space. As transwarp space exists beyond the laws of reality, it is even possible to travel through time itself by crossing it. The ultimate expression of the technology came with the development of the portable Transwarp Drive, powered by transwarp cells, which removed the need for a fixed departure/arrival location system and allowed whole vessels to independently voyage across time and space at will.

However, its widespread use does not necessarily mean that transwarp space has a glowing reputation. The precision and energy needed to access it often makes the technology required very temperamental, and hugely susceptible to disruption if its delicate balance is disturbed. Make one wrong move when voyaging through transwarp, and it is very likely that you may not end up in the same time period, or even the same universe, than you started in... if you're fortunate enough to end up in a universe at all, and not cast adrift in its formless non-space. And even this is not the worst that could befall a hapless castaway, because despite its seeming emptiness, transwarp space is home to a collection of enigmatic, malignant, shapeless entities, and for them to take notice of a stranded traveller is a fate far worse than a mere eternity of solitude. Fortunately, the inhabitants of one of the older, more advanced realities have appointed themselves stewards of the multiverse and taken it upon themselves to trawl transwarp space, oftentimes rescuing both the on-purpose and the accidental travellers that find themselves lost in its unending expanse.
