Regina

Regina is a character in Band Blunders, portrayed by Raina when another cast member is required. She is the twin sister of Raina, and the younger sister of Meara.

The only characters Regina has interacted with are Liam (possessed by Autocorrect), Raina, and Hunter. In iDead 2: Autocorrect's Revenge, Raina mentions that Regina is at their house, meaning she has interacted with Meara off-camera.

Films
In iDead 2: Autocorrect's Revenge, Liam, possessed by Autocorrect, kills her with a battle axe and a hammer. In Halloween, she helps Hunter search for Michael Myers, who later kills her.

Regina is mentioned in Christmas with the Blunders by Rebekah, who also mentions Autocorrect. Neither Hunter nor Kimi know who she is, meaning the iDead franchise and Christmas with the Blunders exist in the same timeline. Christmas with the Blunders takes place after iDead 4.

Regina is cast to appear in Halloween II as a dead body. She is also going to appear as a ninja in The Highlighter Ninja: Phase 2.

Raina and Regina
Raina has usually never appeared to be fond of Regina. In iDead 2: Autocorrect's Revenge, she has a phone conversation with Regina. When she hangs up, she exclaims that she hates her twin. Raina, Meara, and Rebekah never find out that Regina was killed.

However, in Halloween, Raina is upset when she finds out that Regina was most likely murdered (they never got a confirmation, but it was made very obvious to them).

Raina has mentioned that she does not want Regina to return in any movies unless absolutely necessary.
