After adding a character, you can quickly change its expression, pose, or perspective without deleting and reinserting it. Here's how:

  1. Click once on the character to select it. This reveals the Character Tools on the ribbon.
  2. Click the Design tab.
  3. Use the buttons in the Styles group to adjust the style of your character. The options will be different for illustrated and photographic characters.
    • For illustrated characters, you can change Character, Expression, Pose, and Perspective.
    • For photographic characters, you can change Pose and Crop.
  4. Use the buttons in the Arrange group to change the character's layer, alignment, or rotation.
    • Bring Forward: Click this option to bring the character forward one layer on the slide. To move the character to the top layer of the slide, click the small arrow next to Bring Forward and choose Bring to Front
    • Send Backward: Click this option to send the character back one layer on the slide. To move the character to the bottom layer of the slide, click the small arrow next to Send Backward and choose Send to Back.
    • Align: Use this option to align the character with the slide or with other objects on the slide.
    • Group: Grouping is a handy feature for moving, resizing, rotating, flipping, or changing other attributes of several objects at the same time. To group objects, hold down your Shift key while selecting two or more objects on the slide, click the Group selector, and choose Group. To ungroup objects, click the Group selector, and choose Ungroup. To regroup objects, click the Group selector, and choose Regroup.
    • Rotate: Click this option to rotate the character. Choose one of the options listed or choose More Rotation Options to enter a specific rotation value.
  5. Use the Size group on the ribbon to crop or resize your character.
