Drakon, take a Spinarak and name him ArachNed. This Spinarak is desperate to prove himself as the toughest bug-type around. In trainer battles, he can never switch out, as that would show weakness. In addition, he must learn and keep Scary Face, and use it against any Fire, Rock, Flying, or Psychic foes he sees, just to prove his own bravery. To evolve, he must solo at least one trainer in six gyms. Good luck!
