Serial Number= RC-2628
Nickname= (i'll let you guys pick one and if I like it I'll go along with it.)
Appearance= Black shoulders, arms and leg plates with a red stripe down each limb and shoulder pad. 4 red circles on his left breastplate indicate his position as squad leader.
Specialty= Squad leader
Personality= RC-28 believes in protocol and formality. Virtues he believe are the important traditions to any military force that keep everyone humble and on their toes, as well as demostrate the pride of the republic military ethos. As such he will always refer to his squad mates by their numerical designations rather than their chosen or given nicknames. 
This si not to say in a battlezone he will insist on ramrod straight posture or the flourish of a parade ground stomp. There is a time and a place for everything. 
In combat he can be swift and hard towards the droids of the seperatists, if he desires it. Towards the souless enemies like the droids he could care less. Even the other members fo the seperatists he will kill swiftly and without hesitation. He prefers to use his wrist mounted vibroblade.

Ill see if I can add to it later
