No, that title isn't a typo. 😉 I see many CO players running alien PCs, but most of these are either some variation of Qularr or Gadroon, or else completely original species of their own creation. This is natural and understandable for players who are only aware of those alien races shown to them in CO. But the published PnP part of the setting includes a very large and diverse array of official alien races, with their own distinctive appearances, attitudes and cultures, technologies, and often physical abilities beyond what Humans normally possess. Moreover, many of these races can manifest super-powers just as Humans can; although almost always less often, at a lower average power level, and/or over a narrower range of abilities, than Humanity. This maintains the convention from comic books that Earth's superhumans are our equalizer against alien invaders, whose median level of technology can be significantly higher than Earth's (outside of some superheroes and villains). But a few alien civilizations are advanced enough to deliberately induce super-powers in themselves if they wish -- or even in other species.
The great majority of official alien species in the Champions Universe are described in the source book called Champions Beyond. I counted around eighty races native to the Milky Way galaxy named in CB, with descriptions ranging from a single paragraph, up to twenty-page chapters. That total doesn't include Champions races who are extra-galactic, extra-dimensional, or officially extinct, which would easily raise it over a hundred. Their physical forms vary tremendously. There are many humanoids with Star Trek-style features distinguishing them from humans: differently shaped heads, unusual skin colors, fur or feathers, etc. Many beings resemble Earthly animals: cats, dogs, rats, armadillos, birds (flying or non), lizards, turtles, snakes, frogs, several different insect species, centipedes, fish (water-breathing), crabs, and others. A few look like nothing on Earth. There are examples of sapient, mobile plants and fungi; beings made of solid minerals; and a few composed of pure energy.
Level of technology also varies greatly among the official races. Some civilizations are more advanced than Humanity, up to seemingly supernatural or even godlike capabilities. Others are roughly comparable to Earth in the present day, or the near-past or -future. A few have much less advanced tech. However, not having the technology to travel between the stars on their own does not necessarily preclude a member of any alien race appearing on Earth. Accidents such as encountering unexpected wormholes could drop a relatively primitive space craft into the vicinity of Earth. Experimental spaceship drives or teleporters could bring an explorer or refugee to this planet; two aliens currently on Earth, where they're known as Nebula and Vibron, used a one-way teleportation gate all the way from the Andromeda Galaxy. Someone could always steal travel technology from a more advanced society; that's how Ironclad of the Champions arrived on Earth. Some aliens may kidnap members of other species for experimentation or as slaves; the Malvans (whom some of you have seen in-game at the Forum Malvanum on the Moon) have a penchant for seizing aliens for their gladiatorial games, sometimes augmenting them to make them more powerful gladiators. An individual's super powers might also include the ability to travel to Earth; a member of the Vayathuran humanoid race, called Far-Strider, has the power of interstellar-scale teleportation, which he uses to explore the galaxy.
It was my desire in starting this thread to make more of this alien lore accessible to interested people who were not aware of Champions Beyond, or are unwilling or unable to purchase it. But I was daunted by the sheer volume and diversity of information available. I was also hesitant to cherry-pick from the lore, not being sure what people in this community would want to know. So I decided the most efficient course would be to throw the topic open to all of you. If you have a concept for an alien PC or NPC that you didn't know if an existing official race would fit; or if you're looking for an alien-based origin for one of your Terrestrial characters; or if you want more background info about aliens in the setting, generally or for any specific civilization, including ones already in the game; you can ask here. I will do my best to offer info and suggestions (within the limits of Fair Use of the IP), and I welcome anyone else familiar with the lore, or with creative ideas of their own, to add their input. It's my hope that as the discussion builds up over time, this thread will become an inspirational resource for folks wanting to add more ET to their CO experience. 👽
