As a child, Phineas has a large amount of optimism. He pushes forward every time he makes a daily plan. This is what lets his plans succeed, as most children would simply give up once the plan calls for challenging tactics. Usually, Phineas will see the bright side of life, and when faced with a challenge, Phineas will simply find a way to get through it.
Phineas's feelings for Isabella are somewhat unclear, and seems to enjoy hanging around Isabella as a friend most of the time.
