Swoop

Swoop is the friendliest and most outgoing of the Dinobots. He's surprisingly good natured, kind, and upbeat. Few of his comrades realize this however, as his team's reputation and his alt-form, considered (for some reason) particularly "horrifying" to Transformer aesthetics, makes others wary of getting close enough to learn about the bot himself. Swoop is an excellent aerial combatant and bombardier, and has become skilled at using the fear his alt mode creates in battle. He considers it his greatest weapon. Like all the Dinobots, Swoop tends to be arrogant, disobedient, and generally disagree with Optimus Prime's leadership style. He's also a bit of a show-off.
