Shere Khan (Reconnect)

A tiger from a deep, untamed jungle. He hates humans of all species, so he was outraged when he found that one had joined a pack of wolves. He allied himself with Xehanort and the Horned King in order to kill the boy, Mowgli, and gained control over the Heartless to make his search more productive. Shere Khan was eventually defeated when battling the keyblade master, Sora, and fled for a while into the jungle's deepest regions. He later resurfaced to try again to kill Mowgli, but this time, his anger and pure hatred consumed him, giving him more strength and intimidance than before. Shere Khan was defeated again when Sora knocked him into a volcano, imprisoning him within a tiger's stone head.

There's also an anthro counterpart of Khan living in Cape Suzette, though he's allied with Maleficent rather than Xehanort and the Horned King.

During the final seige of Annuvin, a cauldron born skeleton was transformed by the Horned King into a zombie replica of Shere Khan, and then was sent to battle our heroes. The Shere Khan clone, along with the rest of the Cauldron Born and Heartless Soldiers, was destroyed when Gurgi plunged into the Cauldron to stop its evil powers.
