Rend is your basic Changeling soldier, albeit a rather tough one. Loyal to his Monarch- Queen Chrysalis- and willing to die for her and the good of the hive.

That loyalty was tested, though, when Princess Cadence and Shining Armor blasted almost every single Changeling out of Canterlot with Love Energy.

Almost every Changeling

Rend has the misfortune to be caught between a building when the blast hits him- nearly killing him. That was bad enough. Things go from bad to terrible when he tries to feed and a Royal Guard pony intercedes.

Things go downhill from there.
