It may be assumed that Korra already knows metalbending since she has "Mastered" Earthbending. Bloodbending was first come across in one of Aang's miscilanious adventures. The power was shown to Katara by a specifically old and angry old women from the Southern Water Tribe (Whom also happend to be a Water Bender) who was captured during the first Fire Nation raids to capture all the water benders. She learned Bloodbending and escaped, then she lived in the Fire Nation as a Non-Bender until Aang came along. She had been taking the towns villagers into a mountain cave and imprisoning them. Katara over powered her in an epic Water Bender battle which forced Katara to use Bloodbending to subdue her.
