Here's a look at Drake Mantiful. He is one of Rover's best friends and a fellow student at Chilriva School.
Drake's class is Arms Student and his skill type is Armanuevers.
Drake is a very versatile party member. He doesn't excel at any one thing in particular, instead he has a variety of skills that achieve a variety of results. Drake uses Arms for weapons, which is basically a weaponized glove. I'll take this time to note that Attacks always have 100% accuracy; it is impossible for your character to miss. Drake's Arms are pretty standard--he does just punch people after all.
Where Drake's true potential lies as a good party member is in his Armanuevers. As mentioned, Drake can do quite a bit with his skills. He can drain HP, go on the defensive for others, remove status ailments from allies, and even debuff the enemy. Everything Drake can do, others can do better. But that is what make Drake good. In a game where each action counts, having someone who can do multiple things is good to keep around.
Drake's Level 1 Decisive Skill is Power Punch. This is a very strong physical attack that pierces Defense. He has a lot going for him as a party member, but Drake does have one flaw: he has no good ways to damaging the entire enemy party. In Untold Story, monsters attack in large groups. Drake's skills generally only hit one target though.
