Due to Arven being the most athletic student in the academy, he has a super-buff bod and lifts nearly ten times his own weight with ease; this makes him incredibly strong and durable for his age. In fact, the hefty camping bag he carries is practically light to him, despite all the items it contains, some of which are naturally heavy. Though there are times when he physically trains himself, preferring to do Cross training or heavy-duty weight training.

Also, his brief time in Area Zero made Arven a strong battler to the point where he could easily obtain Champion rank if he wanted to; though, due to the accident with his Mabostiff, his confidence took a dive to the point where he doesn't believe in his own battling strength - actively calling himself 'a weak trainer'. This is why he relies on the player for assistance when battling the Titans. Not to mention that, despite his looks, he possesses smarts that nearly match his strengths due to (originally) wanting recognition from his parent; he poured some of his time into studying some of his parent's research, which he didn't understand at first, giving him a much broader understanding of certain topics that aren't normally privy to normal folks. Though he quickly forgot most of it sometime later, it partly stimulated his interest in research and helped him in his other studies at Naranja/Uva Academy - solidifying his position as one of its top students.

It helps that since he basically raised himself, he's quite adaptable in a variety of normal situations - which compliments the advanced growth rate that he's inherited from his parent. Ironically, he's financially competent and stable despite generally being an outdoorsman.
