Coming in at #7 on my 2023 top action figure list was this Back to the Future Ultimate Doc Brown (Hazmat Suit) by NECA Toys.
This figure shipped right at the beginning of 2023 and came with a pile of accessories. There are alternate arms that are fully sleeved with gloves for handling uranium. It also has an alternate head that looks a lot like Christopher Lloyd circa 1985.
