Here is a brief run down of the cast of Starship Chimera, but note that Star Trek names are used in the parody movie, and are not for any kind of profit. They are not officially endorsed.
This is what we gathered from looking at the three parts, and some some of the back stories about
JEAN LUC PICARD
In his 80s during the events of the story, born in 2305, he was commander of two starship Enterprises from 2364 to 2384. He retired at some point, but was reinstated as an admiral by the time of 2388. But he is more like 70 and acts younger.
GEORDIE LA FORCE
In his late 50s during the story, he was an engineering officer on two Enterprises in the 2360s to 2380s. He is made commander of the Enterprise E on her last mission beginning in 2388.
WILLIAM RIKER
In his 60s during the story, he was first officer on two Enterprises in the 2360s up till 2379 when he took command of the Luna class Titan. The ship was evidently lost after that, and the Excalibur class Titan A was commissioned at about 2386. He still commands the ship.
WORF
The Klingon officer is a security chief from two Enterprises, from Deep Space Nine, and the Defiant. He served as first officer on the rebuilt Enterprise E in 2388 on her final voyage, but during the incident opted to help Riker's ship instead.
DEANNA TROI RIKER
She is about in her middle 50s, and was counselor on two Enterprises. She appeared to be first officer on the Titan A in the 2388 incident.
NICHOLAS LOCARNO
Nick is the same age as his twin, Tom Paris, about 50, With a parallel life to his twin, Tom Paris, and a darker redemptive arc, he wasn't lost like his brother, but was captured by the Cardassians during the Dominion war, and rescued, where he saved the starship Exeter, under Captain Sarah Esteban and first officer Ro Laren. Having done his time, so to speak, he was brought back into Starfleet where he served with distinction, but had a knack for getting into trouble a little. As commander of the Chimera, he was caught up in the incident of 2388.
EZRI DAX
Former host counselor of Deep Space Nine and first officer on the Chimera, she is a Trill alien with a plucky streak who likes to mess with people. Present on the mission in 2388 and an intergral part of solving the problem.
KIRA NERYS
Bajoran resistance fighter and commander of Deep Space Nine following Sisko's disappearance after the Dominion war, she has made General rank and presides over the sector, including Cardassian space, ironically since they used to be enemies.
KATHRYN JANEWAY
Commander of the Voyager in the 2370s in the delta quadrant, made rear admiral by 2379, she is still that rank during the 2388 incident and helps the Chimera and crew.
SETO JAXA
A lost ensign officer from the Enterprise D who was found on a Cardassian prison world in 2376 at the end of the Dominion war, and rescued. She later would serve on the Enterprise E and on the Chimera during the incident in 2388.
MAJ BOLO
The tripping out helmsman of the Chimera put in his early report to the Enterprise E during the late 2370s that he wanted to be part of the Borg, but they rejected him. He was a Kazon alien from the gamma quadrant who evident came back with Voyager, possibly as a youth. Assigned to the Chimera during the mission.
KRASS
Krass is the little sister of Bellana Paris, and aunt of Miral, born before the Voyager left in 2371, given that she is a very young officer on the Chimera. She has a lover, Klank, who threatened the ships in 2388 but she killed him later on the alien planet.
AYER
Ayer is an older male Klingon who is the Chimera ship's doctor and seems to have taken a liking to the Tal Shiar Romulan intern T'Abby during the story.
T'ABBY
This Romulan intern doctor on the Chimera has a striking resemblance to Natasha Yar from the old Enterprise D, and may be a sibling of Sela of Romulus. She was not a daughter as she looks to be roughly Tasha's age if she was living, in her early 50s. She had a thing for Ayer.
WESLEY CRUSHER
The Mozart of space time was back, in his late 40s, and chief engineer on the Titan A during the 2388 incident.
VINCE MAHONEY
The wise cracking former prisoner from the Maquis people on the Carassian colony, where he, Krass, Locarno, and Seto were held, had issues, according to his record. He and Krass were the youngest, in their early 20s thus currently in the story. He and Krass joined starfleet and learned to tolerate each other. Evidently they did not bond terribly well in space prison, but helped each other out as friends.
Q
He is a space being that can control space and time, and is omnipresent somehow.
LOREUS
He is an Overlord of the Sillian renegades under Funnel's crew who had come through space time to steal the destiny device in 2388. He would be the same age as Data if he was living, but is an android.
HARRY CRENSHAW
He is an Overlord from the Silliams who liked Henry Barrister and wanted to be just like him, and was led into a life of crime working for Loreus.
