Tac

Tac (originally known as T.A.C. in Kirby Super Star) is a cat burglar enemy featured in some Kirby titles. It makes its first and main appearance in Kirby Super Star. Here, a Tac can steal an ability from Kirby or his helper. If Kirby inhales a Tac, it either returns the stolen ability to him or, if holding nothing, grants him the Copy ability.

Super Smash Bros. series
Tacs appear in Super Smash Bros. for Nintendo 3DS as enemies in Smash Run. They can steal a fighter's stat boosts, and defeating a Tac causes it to drop the stat boots they have stolen. Tac's main attack involves launching his hand at the player's figher, which does 1% damage (it cannot be reflected or absorbed, but it can be shielded and countered without losing stats). Tac floats away after some time.

In Super Smash Bros. for Wii U, Tac is featured in the Smash Tour mode. It appears as a random event, carrying several stat boosts that are awarded to whichever fighter that runs into it.

In Super Smash Bros. Ultimate, there is a spirit of Tac that uses his Kirby Super Star Ultra artwork.
