Alexander "Alex" Aruda is one of the smartest kid in Greg Heffley's class.
Alex Aruda is regarded as one of the smartest people in Greg's class and Greg often copies his answers because he puts his test on the floor after he's finished. Not much is known, apart from that, but he does his teacher's tax returns and is in Mr. Halper's Helpers. He is a recurring character and is likely to return in future books.
