I had many, many favorites, but two stand out in my mind:
Agent Andrea Blake and
Agent Sorina Tavarisch.
Tava's story is still being chronicled in THE COURSE OF SUPERHERO ROMANCE, but as that's set one year behind the last in-game events of COH, there is still the matter of her being removed from the picture so Positron can get on with courting Numina.
Blake deserves a book series of her own, though... she was just so much FUN.
*sighs*
It's funny - the stories and moments that defined both of them came from external sources.
Tava was created to a) sort of fill one of the 5 leader slots for Star Patrol, and b) test the grav/kin controller power set. I sort of knew her backstory, but it wasn't until one night when I was casually RPing with a fellow SG member (where after helping to defeat Anti-Matter, she whips out her cell phone to call Positron and let him know, and agrees to meet him for coffee) that the whole "Tava's in love with Positron" thing came to life. And then the rest of her story came to life along with it.
Blake was created when a fellow SG player asked, "How well does the dark/psi defender play?" So I created one, who also became one of the 5 founders of Star Patrol. And my little "Danger Mouse" superheroine was born. I still want to commission someone to do an art piece of her dancing the tango with Statesman at a charity dance after she bullied him into it.
I miss them both so much.
