Animorphs The Invasion (Audiobook)
Teen Dash for Tom
Tom is Jake's older brother and is in an organization called The Sharing at school where he's a full member. He's an extremely important Yeerk and is very egotistical when he's showing his true colors.
"Jake, you got Homer in there with you?" *pause* "Mom's on the phone, stop him yapping-"
"Flying saucers," *pause* "Only complete dips believe that kind of stuff." *pause* "You don't believe in that, do you? Aliens and spaceships and little green men from Mars?"
"It could have been anyone," *pause* "But it MIGHT be the one who's my brother, Jake. I know he goes through the construction site sometimes. That's why I brought him here tonight. So we could either make him ours... or kill him."
Tom has a more calm, trusting voice. People look up to Tom, and he's also being controlled by a very dignified alien parasite.
