As PowerPoint does not support animations, any animation in the Powtoon that you export (including a character's animation) will not be included in the PowerPoint file. All objects with animation will appear as static objects.
The slides in the PowerPoint are snapshots of the slides in your Powtoon, taken 0.5 seconds before the end of each slide.
