The 2019 Marvel Unlimited subscriber figure has been announced as Venomised Punisher. This is a repaint of the existing Marvel Legends 6" scale Venom, now with Punisher logo. The figure also includes a couple of guns, previously released with Forge.
The figure is free with a subscription package to Marvel Unlimited and will not be released elsewhere. Previous exclusives have included Pepper Potts Rescue Suit and suited Tony Stark.
Sadly, the subscription is only valid for US customers so there is no easy way to obtain this as a UK resident.
