Name: Everyone's got a name. That said, naming standards very widely from planet to planet and species to species. So name your character whatever you like.
Species: What race is your character? Humans are the most common. If not human, include some details about how your race differs from them, and if you like, some history.
Gender: List whichever your race is closest too.
Age: How old is your character? Most anything is acceptable here, seeing as some races have lifespans spanning only a decade, while others can live hundreds of years, barring accidents.
Position: If you're a member of the rebels, what do you do as a crewmember? They don't have a single rank for "Captain" or "Leader". The players need to decide to elect one themselves, or simply share the role amongst themselves. Also, you will need a pilot. The pilot gets to choose what each ship the crew gets looks like, and, of course, use it in battle.
Appearance: What does your character look like?
History: Optional, although it is nice.
Techniques: What does your character bring to the table in a fight? Do they combine ki and martial arts, imbuing their fists with lightning? Or are they a defector from the Alliance Military, wielding grenades and a plasma rifle? Or perhaps they are a trained assassin, with a cloaking device and a pair of katanas? Or maybe an alien who has mastered the natural weapons of their race, firing spikes from the backs of their forearms and spitting acid into your foe's eyes. List three or four "moves" your character has. If your character is skilled in their weapon being just having a general knowledge of where one holds it, that should also take up a slot.
Skills: What can your character do outside of a fight? Stuff like hacking computers, first aid, and repairing machines goes here.
Equipment: What does your character typically carry with them?
Other: Anything else you want to put?
