Jessie showed absolutely no mercy toward Seviper

It should have thought twice before biting her hair off.

The scratches on poor Seviper’s face were inflicted by savage Jessie

That's what might happen to you if you mess with her hair.

Living proof that Jessie can be way scarier than even large venomous snakes

Just look at those red glaring eyes - I would not want to be in Seviper's place right now, and neither would James or Meowth.

James and Meowth are hugging each other for dear life

They're extremely terrified by what Jessie's gonna do to Seviper for ripping her hair off.

For biting Jessie’s hair off, Seviper is about to face her wrath

Jessie didn't ask for this haircut, so she's going to make Seviper pay.

Jessie is devastated once she realizes her hair was just cut off by Seviper

Meanwhile, Seviper just stares at her with her hair in its mouth.

Did Seviper just bite Jessie’s hair off?

That was its way of telling her to back off, but maybe it went too far.

Looks like someone scared the daylights out of James and Meowth

It's probably safe to assume that Jessie is the culprit.
