In-Betweeners

Introduced in GURPS Voodoo which stated "these beings are not spirits, either, but entities trapped inside a physical shell, supernatural but still material." GURPS Spirits restated this adding in the detail they are affected by spirit rituals.pg 45
In-Betweener Invulnerability (60 points) converts to Supernatural Durability (150 points) with Unkillable 1 (50 points)
Regeneration is 25/50/100 points as in 3e.
However it is unclear how to convert the key aspect of being both spirit and material to 4e. They would have Affects Insubstantial on their attacks, but be vulnerable to insubstantial creatures even if they lacked Affects Substantial on theirs.
