Adam Pike is Mallory's nine-year old (later ten) brother. He has 3 brothers and 4 sisters. Adams's brothers are Nicky Pike, Byron Pike, and Jordan Pike. His sisters are Mallory Pike, Margo Pike, Claire Pike and Vanessa Pike.
Like the rest of the Pikes he has dark chestnut hair (sometimes described as brown) and blue eyes. Adam is the middle triplet; he is 40 seconds younger than Jordan and two minutes older than Byron. He is the most "boyish" and he is once called the "Terror of Slate Street."

He is the most "boyish" and he is once called the "Terror of Slate Street." They know how to speak Pig Latin and even taught Mallory in case they ever needed to say anything in private.
They decide that they are too old for babysitters and organize their own kickball league to mixed results. They used to be a part of the BSC's Baby-sitters-in-training along with Jeff, but they quit because they decide it takes too much time and they have better things to do.
Adam, Bryon, and Jordan plays in the local little league. In Claudia and the Mystery at the Museum the triplets go to soccer practice. In Dawn and the Impossible Three they go to ice hockey practice. Together Adam, Jordan, and Byron are the most active kids in the Pike family, but Nicky is not so active because he is the youngest. In Claudia and the Middle School Mystery they don’t snitch on each other when a window is broken while playing ball. They call themselves the 3 Musketeers.
