Requires Grapple

The Weird pg 21
pg 33's example "Supercharging" shows it also works when someone grapples you, which is in like with GURPS Martial Arts: Technical Grappling' ruling that grappling is MUTUAL.
==Comparison==
This has the same cost of Increased Immunity limitation, while the inverse enhancement No Contact Required has the same cost of the Decreased Immunity enhancement.
==Prior usage==
Prior to this 2016 supplement, this 2015 thread mentions:
:Mutants and Masterminds, somehow. Grabbing a guy, triggering all your "requires grapple" powers
Implying the phrase may originate in Mutants and Masterminds. This 2017 archive for example has:
*AE: “Crush” Weaken Toughness 14 (Extras: Affects Objects)(Flaws: Requires Grapple){14}
*AE: “Crush” Melee Strength Damage + Weaken Toughness 14 (Extras: Affects Objects)(Flaws: Requires Grapple){14}
==see also==
*Delivered by Grappling an Extremity
*Half Damage Without Grapple
*Immediate Crippling
*Leech
*Must touch with suction cup
*Required Grapple Points
