Landon is Troy Jeff's best friend. He does not know about Troys secret spy identity, but starts to suspect something is up when he always can't hang out, is late to class, and is at school at 5 am. When needed though, Landon will always have Troy's back, no matter his suspicions. He is also athletically inclined, although he prefers basketball.
Coach Solomon is the founder of Ackerman Agency, and is undercover as a gym coach. When Troy first enters the school, Solomon takes a liking to him, and wants him to join the agency, but Troy manages to find it on his own.
