One of the minor (he doesn't even get the extra mention in the song we sing afterwards) characters in Megillas Esther is named Hatach. Who was he? In Megillah 15a Chazal identify him as Daniel, the same one who has a whole book of TaNach named for him. The change in name is said to refer to his having been cut down [chatchuhu]from his greatness.
The Meshech Chochma on Megillas Esther offers a novel reason for his loss in status. He says that his greatness among the Jews was due to his willingness to sacrifice his life for a mitzvah. He incurred the penalty of being thrown into the lion's den for having prayed three times a day. He survived through a miracle.
