Unnerve is one of the many abilities that are inheritable by Pokémon.
Function
If the opponent is actively holding a berry, Unnerve will preclude them from consuming it; this is considered strategic because by debilitating the opponent from potentially consuming a berry, it may parry off any strategic use they might have intended for it.
