The Cretan Minotaur is a monster summoned by the Trix, serving as an antagonist in the Season 1 episode Grounded.

The Trix summoned the minotaur from limbo to attack the Winx, who were left behind during a concert that everyone else at Alfea was attending. Since their powers had been taken away, the Winx were unable to do anything to him at first, leaving the specialists to fight him. The minotaur gained the upper hand, but the Winx got him to chase after them, then Bloom and Musa poured soap in his path, causing him to slip and fall to a lower level, knocking him out. The minotaur was then captured by the specialists, and presumably imprisoned.
