Imagining how characters from completely different shows would react to each other is an entertaining pastime of many sci-fi geeks. Many times, the interaction between these worlds require some sort of time travel, which some sci-fi geeks will warn is impossible. Fortunately, the “impossible” fits nicely in the realm of sci-fi, and makes all interactions “possible.”
“Battlestar Galactica” and any “Stargate” variation
“Battlestar Galactica” takes place in the past, and “Stargate” takes place in the present. Once the logistics are worked out, however, it would be fascinating to see how humans from the present, using alien technology from the past, would react to meeting their highly advanced ancestors. It would also be fascinating to see how the Cylons would react to learning the truth of what will happen far in the future.
“Star Trek” and “CSI: Miami”
This may seem like a strange pairing, but they both have something in common. They are both wonderful because of their hilarious cheesiness. The Enterprise could travel back in time, and crash land in Miami. Horatio and his team would get the call, and drive out to investigate.
Captain Kirk (William Shatner) would stumble out of the ship first, and walk up to “their leader,” Horatio (David Caruso). With his pretentious pseudo-Shakespearean manner of speaking, Kirk would say, “We come in peace.” Horatio would reply, in his best David Caruso voice, “You landed on my best man, and I won’t rest until I put you in away, forever.” Then Horatio would put on his sunglasses, and motion for Frank (Rex Linn) to arrest the entire crew.
“Firefly” and “Castle”
The “Firefly” crew could have an accident that hurls them back in time. They decide to visit Earth, since it’s the only place with humans (terraforming has not yet taken place). After landing, they just happen to run into Castle (Nathan Fillion), a man who looks exactly like Mal (Nathan Fillion). Beckett (Stana Katic) thinks they are lying about who they are, but Castle gets overly excited about the situation and offers to let them stay at his place for awhile. Hijinks ensue.
“Doctor Who” and “Greatest American Hero”
The Doctor (Matt Smith) visits America, expecting some cowboy-hat-wearing-fun. Then he spots Ralph Hinkley (William Katt), aka “The Greatest American Hero,” clumsily crashing through the air, right into the TARDIS.
“X-Files” and “3rd Rock From the Sun”
Imagine how surprised Scully (Gillian Anderson) would be to find real proof of actual aliens living amongst humans on planet Earth. Now imagine how surprised she would be to find that they are a bunch of morons. Mulder (David Duchovny) would initially be ecstatic, then realize that his long search for the truth was a total joke.
