Sundor

Profile: Sundor is a relatively new recruit amongst the Cybertron Cassettebots. However, he never shows any respect for his more experienced seniors... or rather, he doesn't realize that he should. Due to his extreme confidence in his blindingly shiny body, the only thing that Sundor respects is the beauty of the sun as he looks up at it from Earth.
Sundor was originally a Destron Cassetron warrior, but he was affected by sunspots while passing through the Space Bridge from his home planet of Cybertron to his assignment on Earth. This caused an abnormality in his component molecules, giving him a mutant body that glows with a unique light that cannot be explained by current Cybertronian science.
Shortly afterwards, Sundor cut off communications. He did not join the Destron Earth Army, but instead appeared as a Cybertron warrior. Rumors spread throughout the ranks that the sunspots had affected his logic circuits and driven him mad. Nobody yet realizes that this is a top-secret spy mission to which only Sundor and Megatron are privy. The Cybertron Broadcast, who had been suffering from a lack of aerial support compared to the Destron Soundwave, welcomed Sundor without suspecting a thing.

Ability: Sundor's twin automatic-targeting blasters can fire 10000 degree Celsius Corona rays that can melt even Trithyllium steel, but his rapid-fire chatter is even more powerful. Sundor's pride and joy is his beautiful shining skin, which not only repels null rays and laser rifles but is also impermeable to physical missiles and ammunition.
Sundor's cassette mode recording module is primarily full of information on the sun, and he continues to record the constant changes of the sun. The sight of Sundor soaring through the sky with a fiery tail trailing behind him is such that, even if an enemy warrior were to find him, he would be so entranced by the sight that he would forget to pull the trigger.

Weaknesses: However, Sundor's abilities are all absorbed from the sun, and his confidence begins to cloud over at night when the sun is absent from the sky. In order to prevent others from realizing this, Sundor flees the battlefield, claiming that staying out late is terrible for the skin.
Sundor is criticized by his comrades for his self-centered attitude and tendency to look down on others. He refuses to change his behavior, however, for he knows deep inside that he will never be able to surpass the sun.
