* CatharsisFactor: For fans who disliked Gwen always being "little miss perfect" and rubbing Ben's screw-ups in his face in the Original Series. Here Gwen is directly responsible for everything going wrong, a refreshing change from Ben just messing up again.
* InferredHolocaust: An ''entire city'' is heavily damaged and destroyed during a fight with [[spoiler:Way Big and Tokustar!Azmuth]]. WordOfGod is that it had to be rebuilt by alien immigrants who went on to found [[WesternAnimation/Ben10Omniverse Undertown]].
* SugarWiki/VisualEffectsOfAwesome:
** Upgrade's morphing abilities look REALLY great here.
** Heatblast and Diamondhead also look really good in CGI.
