List of abilities used by Sophie the Otter

Attacks

 * Tail Slap: Hits enemies by swinging her tail. Rather basic.
 * Liquid Squirt: A regular attack involving her shooting water out of her mouth to give minor damage to enemies.
 * Aqua Current: An attack where Sophie propels herself on a water current and giving an average amount of damage to enemies. It is her Side-B move in Theory Smash Brawl.
 * Whirlpool Trap: Traps enemies in whirlpools of water. While trapped, target(s) take(s) damage.
 * Bubble Breath: Shoots bubbles of various sizes out of her mouth to trap anything.
 * Water Column: Sends out a column of water going upwards, attacking the target. Her Down-B move in Theory Smash Brawl
 * Tsunami Attack: An attack where she sends forth a medium-sized Tsunami to attack opponents.
 * Water Storm: Her largest and strongest attack. She hops up into the air and releases an extremely large blast of water with her paws.

Abilities

 * Climbing on walls.
 * Extending her tail.
 * Bubble Shield: Encases herself in a bubble, protecting her from anything but sharp objects like spikes. It can also evolve into Flying Bubble, where she floats inside it completely as the bubble flies.

Forms

 * Inflated Sophie: Happens when Sophie uses a move called Bubble Inhale where she inhales a bubble that appears. The shape of the bubble expands her body and floats her up into the air for a few seconds.
 * Kangaroo Sophie: Whenever Sophie possesses Nate Summers' kangaroo amulet, Sophie becomes a kangaroo. In this form, she has increased agility, can jump higher, and can store up to 10 objects in her pouch. It was first demonstrated in the episode Let's Bounce! and will be an available form in any Theory games that are released after the episode's airing. However, Sophie loses her water attacks in kangaroo form and can only attack by stomping and using items inside her pouch.
