I usually enjoy creating characters that have some major flaw in their personalities. In fact my favorite characters are those who are seriously twisted in some way. For one character in Astrid Maxxim, I went a completely different way.
In the Tom Swift books I read as a kid, my favorite character was Tom’s best friend Bud Barclay. Bud was totally reliable and faithful, completely unwavering in his friendship and belief in Tom. I patterned Toby Bundersmith after Bud in that respect.
Of course Toby has to be different in one way– he’s not just Astrid’s best friend– he’s her boyfriend. In fact, she often daydreams of one day being Dr. Astrid Bundersmith, so he has to not only be great, but dreamy as well. Toby is my perfect boy. He never wavers, he’s always supportive, he’s always reliable, and always responsible. He can’t save the day, because Astrid is the hero of the story, but he’s always there to back her up. If someone has to come to Astrid’s aid, it will be Toby. In truth, he’s pretty boring. Fortunately, there are enough other characters who can cause chaos, doubt, and trouble for our girl inventor.
