Medicom will be releasing a MAFEX Evil Gwen-Pool figure in 2019, number 83 in the MAFEX line. The figure re-uses parts from their Gwenpool figure - but there are new sculpted parts, and it looks like there will be some bonus items for Gwenpool if you purchase her evil version.
While the contents are not confirmed, the promotional images show different head options, including an unmasked version which will also work on your original Gwenpool. Another bonus for your original Gwenpool is a watch accessory. There are floating comic books with a stand of some description, and a mini Gwenpool accessory. She is armed with twin katana blades. Her cape is soft goods and appears to have an wire skeleton to support dynamic posing.
The figure will be released around June 2019 and will be circa £65 in the UK / $75 in the US.
