Bobbies eyes widened and he damn near lost control of his bowels when the aptly named Beast diverted all it's attention on him. The strongest sensation of fear rippled along his body. That same emotion triggered Bobbys transformation and chasing the feeling of fright was the more substantial sense of change as he took on his Alter ego. His dyed hair changed, embodying the flame it was meant to imitate. His clothes too came to life, flickering hungrily, as true a flame as the kind Bobby once tried to make as a scout. Finally, the flaming skull on Bobbies T-shirt woke, the empty eyes Bobby had wrought now glaring at the beast with twin points of red light within the sockets giving a silent roar in return to the Beast.
Unfortunately the transformation hardly dulled the fear. In fact, it only served to almost emphasise it. Anyone nearby could instantly feel the surge of emotion from Bobby, urging them to flee so much they almost felt they were being given energy just for that, to speed their flight.
Bobby would have listened to those muscles if a scream from nowhere hadn't kicked his reactions into gear as he leapt up, the action seemingly involuntary to his conscious mind, and brought his right leg up to kick the Beasts jaw, hoping to stop that terrifying roar with a shocking amount of speed.
