Panther is a member of a mysterious group along with Lion and Wolf that, among other things, aims to hunt down and kill Dante. The trio appear to have knowledge of Dante's identity and purpose prior to the replacement of their head.

He is an antagonist introduced in Prologue: Selva Oscura.

Panther is a rational and observational person, being the one to focus the discussion on what information they could gather. He can also be cruel, as seen by his comment on wanting to see Dante's expression while they died and his remark on The Sinners being so weak that they are no fun to kill. Despite this, he is not overconfident, retreating when told to.
