Aerobic Al is a boy who is keen to do sport in Henry's class. He is the fastest person in the class, the 2nd being Moody Margaret. As a result of this, he rejects eating sweets when offered. When Henry offered Al a yummy gummy fuzzball in Horrid Henry's Sports Day, he couldn't resist, as they are his favourite kind of sweets. He has also been known to be bent to "debag" Henry as revenge for his debagging. He has a Black Country accent and is one of Henry's friends. He is shown to be a member of the Purple Hand Gang.
