|First Appearance||Ben 10: Race Against Time|
Ben is shown to be immature at times (less immature than other versions) and shows deep care for his family.
When it comes to fighting, Ben seems to have no qualms with killing his foes to defeat them, as he, as Heatblast, engulfed Eon in fire to try and obliterate him, and thought he succeeded.
According to Gwen, Ben is a crybaby, as he always cries when Gwen pins him down.
Race Against Time
Summer's over and Ben is back to school. Ben is disappointed that he's not able to tell anyone about his adventures or the Omnitrix. Ben was expecting another boring school year. However, things changed when Eon came in the day before the first day of school causing a fight between him and Heatblast. Heatblast seemingly beats him. Throughout the movie, Ben was always being chased by Eon, who wanted Ben's young power to activate the Hands of Armageddon,causing a 24-hour guard over Ben. In the film's climax, Eon managed to take over Ben however thanks to Gwen, Ben managed to overcome Eon's personality and managed to stop the Chronian invasion. When Eon came back to exact revenge on Ben, Wildmutt managed to throw him into the Hands of Armageddon, thinking he was killed. At the end of the movie he along with Gwen won second prize at a talent show.
In Ben 10,000 Returns, it was revealed that Wildmutt actually threw Eon out of the RAT timeline and into crosstime.
Ben was seen when Gwen in the main timeline used a spell on the Hands of Armageddon.
