Cassie

Cassie is a human from the Animorphs continuity.

Cassie is an Animorph, capable of becoming any animal quickly and easily. She believes that all of Earth's creatures are on her side in the war against the Yeerk invasion, and alongside them and her friends, she is inspired to become a wolf, using her morph's strength, fierceness and speed to stop the invaders' insidious plot. After breaking into the Yeerks' genetic experimentation lab, she and her friends Marco and Jake have acquired the ability to merge and become the colossal Tri-Rex through the use of an advanced morphing technique.

Toys

Animorphs

• Cassie/Wolf (Deluxe, 1999)
  • Accessories: Left paw, right paw

Part of the first wave of Animorphs toys, Cassie transforms from what is evidently meant to be a human into a wolf, as well as a transitional third mode combining features from both. Like many Animorphs toys, she has a pair of wolf claws, the "Raker Claws", that attach to her hands like gloves; unlike the other toys, they are not actually necessary to complete her wolf mode (as it has four paws already), though they can still be used in that mode.

I make Terragator feel inadequate!

• Tri-Rex (Super, 1999)

This version of Cassie was available only in the Tri-Rex giftset, along with Jake and Marco. The toy has neither a human mode nor a complete animal mode; Cassie transforms from a human/dinosaur transitional form into the tail of Tri-Rex.

Notes

• Cassie holds the dubious honor of having perhaps the least informative bio note ever. It mentions her wolf mode, but beyond that it simply reiterates the Animorphs premise, with no information whatsoever that specifically pertains to Cassie herself.
• In both of her toys, Cassie wears what is probably intended to be green overalls with a yellow shirt underneath. She is the only Animorphs toy that does not change clothing from toy to toy. Even Visser Three changes from red to yellow and black in between his Mega and Ultra toy.
• For Cassie's packaging art, a photograph of the actress that portrayed the character in the Animorphs television series, Nadia Nascimento, was used for her wolf mold.
