Krastyo Hadzhipetrov Asenov, nicknamed Mechkata (the Bear), Ogneniot daskal (the Fiery Teacher) and Cherkeza (the Circassian), was a Bulgarian revolutionary figure active in the region of Macedonia, one of the voyvodas of the Internal Macedonian-Adrianople Revolutionary Organization (IMARO) for the Enidzhe Vardar region.

He was a nephew of the famous Bulgarian voyvoda Hadzhi Dimitar and a brother of the IMARO revolutionary Yordan Asenov.

Under the influence of Gotse Delchev, he joined the IMARO and the struggle for the liberation of Macedonia and Odrin from the Turkish yoke.

In 1902, his sister, Doctor Sabka Asenova, preserved a part of the ransom collected from the Miss Stone Affair.

Despite the rumour amongst his fellows, that it would be a bad sign, on 25 July, when the Uprising was still ongoing, he married Ana Maleshevska, the daughter of the voyvoda Nikola Maleshevski, in the village of Kornishor (today known as Kromni), in the Enidzhe-Vardar region.
