Lachlan is the Ultimate Surfer. He's a very laid-back person, having never put much effort into studying and instead spending most of his time surfing and enjoying himself. Despite seeming carefree, he's a lot smarter than he seems, being able to stay calm and collected in stressful moments. He's willing to put in real effort if the situation calls for it. He cares a lot about the people close to him.

He has a male voice with a medium pitch. He usually sounds very laid back and relaxed. An Australian accent would be nice, but it's definitely not required.
