This is what the SYM family would look through my eyes:
*disclaimer*I haven't been here long, don't know most of you at all, so no offence intended with any of this.*
Mr. Sleep: Eldest Son,
Weasel: The beloved yet extremely excentric Uncle who visits sometimes.
Brink: Kid becomes a man and moves far far away. Every time he is back he is showered by praise and stuff because he is rarely visits.
Aegis: Come up with something later
Georgi: Ditto - maybe the feminist of the family
Waverly: Another weird Uncle, The Mad Scientist of the family, has his moments where he can scare the kids.
Minevra: No clue.
Xandax: The families lost case, a spammer in denile!
Fable: Definitely the wise old grandfather figure. Respected by all, heck even when they don't agree with him, they won't flame.
T'lainya: Motherly type - keeps everything running smoothly. (Not really sure about this being true, but that is the image i have).
Flagg: No clue
Vehemence: No clue, though from what i heard, he would the relation who has more women than clothes.
Gruntboy: hmmm...the hardcore member of the family, maybe the one who joins the military.
craig: The youngest and every body is fond of him, even if they don't understand what he is saying.
Yshania: hmmm
Sailor Saturn: Teenage girl - need i say more???
KidD01: No clue
C Elegans: Grandmotherly type, spoils the kids rotten etc.
Drakron Du´Dark: No clue:
Honorable Mention:
BS - the family drunk and Ned is his drinking buddy who is with him constantly!
