Jormungant's G-to-H is either of two closely related stable 2G-to-H converters discovered by Louis-François Handfield (pseudonym: Jormungant) in 2018.[1] The initial stage converts two gliders into a Herschel. (In the infobox pattern, a ghost Herschel marks the output location.) It is the basis of various low period guns.

Unlike most glider-to-herschel converters, this converter's initial glider-block collision converts the block into a honey farm predecessor, instead of a pi-heptomino. The second glider, along with the BTS catalyst, convert the pre–honey farm into a B-heptomino, which forms a block at the original location and produces a Herschel output. There are two possible positions for this second glider; one of these requires the presence of an additional eater 2, as well as replacing the BTS with an equivalent larger catalyst with better clearance.

Without this, it would take 3 gliders to create a Herschel by using the glider synthesis of a B-heptomino, plus one extra glider to delete the B-heptomino's block. In cases such as the original period-52 glider gun, this would not be sufficient to create an over-unity reaction due to the difficulty of extracting 4 gliders from an output Herschel at such a low period. The discovery of this fast 2G-to-H was thus a key innovation allowing these low-period guns to be constructed.
