Shapeshifters can change their form so as to appear as any person living, dead, or fictional. Unlike most monsters, shifters have appeared to have purely human drives that have ranged from jealously, greed and loneliness. It appears that not all the shapeshifters have the exact same abilities: Dean says that the one they encounter in Milwaukee shifts faster than the one they saw in St. Louis. Some must shed their skin, teeth, and nails to change from one form to another. However, Sam and Dean have encountered shapeshifters, such as the Alpha Shapeshifter -- the progenitor of all shapeshifters -- that do not require themselves to shed their skin when they change..
Yeah. I mean, it's human, more or less. Has human drives -- and in this case it's money. But it generates its own skin, it can shape it to match someone else's features, you know, taller, shorter, male,

Crowley comments that through experiments conducted on "lesser" shapeshifters, he has found something that will harm the Alpha: iridium. He holds up an iridium knife and threatens to start removing "the parts that stick out" if the shifter does not start talking. The Alpha still denies knowledge of Purgatory, so Crowley stabs it. He then leans in close, and the Alpha spits blood at him. Infuriated, Crowley activates a baby monitor, over which crying can be heard, and reminds the Alpha that he holds several of its children hostage. He threatens to kill them in front of the shapeshifter, but the Alpha replies "Kill 'em all. We'll make more." Crowley turns away, grabs a machete, and beheads the Alpha.

Several years ago, Bunny LaCroix had an affair on her husband with a shapeshifter and got pregnant. She passed the baby, Olivia off as her husband Lance's, but when they got home from the hospital, the shapeshifter father was waiting. He killed Lance when he tried to resist and tried to take Olivia, but was killed by Bobby Singer before he could. At the pleading of Bunny, Bobby agreed not to kill Olivia on the condition that Bunny lock her up for everyone's safety. Bunny agreed and asked Bobby to take care of Olivia if anything happened to her.
Keeping her word to Bobby, Bunny locked Olivia in her attic, claiming she'd lost the baby and letting only her butler Phillip know the truth. Despite this, she remained devoted to her daughter and Olivia to her. In 2014, Bunny died and Phillip took pity on Olivia and released her, having her disguise herself as the new maid so that she could hide in plain sight.
However, Olivia was not content with the state of affairs and took on the form of Bunny to scare the maid Colette when she tried to steal a pearl necklace. However, this resulted in Colette falling to her death. Phillip covered up the murder and hid Colette's body in the attic, claiming she'd gone off to clown college.

Olivia then killed Phillip to pay him back for locking her up and after Dean found her out while she was in Phillip's form, quickly ran off and returned to her own form. After "finding" Phillip's body, Olivia took Sam and Dean to the silverware where they pulled out what they believed to be silver butter knives and gave one to Olivia to test her. As the knives were actually stainless steel, she passed the test. While everyone was distracted, Olivia murdered Detective Howard by drowning him in the toilet and then after Sam and Dean were locked up, confronted the rest of her family with Howard's gun. Olivia explained her connection to Bunny and reasons for killing everyone, but before she could harm anyone else, Sam and Dean escaped by shooting out the lock of the room they were in. Olivia and Sam engaged in a game of cat and mouse, with Olivia explaining Bobby's connection to her family. Olivia quickly realized Sam had no silver bullets as he wasn't firing at her and prepared to kill him.

Possibly under the influence of the Mark of Cain, Dean then unloaded several more rounds into Olivia's body.
