Part V: Misc. Abilities
Larfleeze and his constructs can absorb Green Lantern constructs--even those created by the Guardians:

*And as the scan also states, Larf's constructs can absorb magic as well.
The Avarice Entity states that Larfleeze is the ONLY being in the universe capable of resisting its temptations, and he was therefore able to enslave the Entity itself:

After all, we saw that even the strongest-willed Lanterns could be fully corrupted by the Orange Lantern almost immediately after touching it...

Larf's constructs can shape-shift, and disguise themselves as other constructs. We see this when Glomulus disguises himself as an Orange Ring that fooled even the Guardians:

*Essentially a construct within a construct.
Larf can also manifest fairly advanced tech-like constructs. Here he states that he keyed his ring in such a way that it continuously monitors all news outlets. He then uses it to watch one such broadcast:

The ring also allows Larf to track others, and circumnavigate the known universe:

When Volthoom attempted to manipulate Larfleeze's reality/timeline, even he was unable to change Larf's essential nature... No matter how many different scenarios he generated:

Volthoom ultimately realized that Larf IS greed/desire/avarice on a fundamental level, and completely gave up trying to manipulate him. He was the ONLY Lantern that Volthoom simply could not break.
In fact, Larfleeze has mental shields in place that prevented Dyrge, a member of The House of Tuath-Dan, from tampering with his mind all together:

IOW, Larf's mind is so greedy...even at a subconscious level...that it cannot be penetrated by psychics.
Larf alludes to being the first Lantern in the universe to manifest constructs:

*And because Larf always has the battery with him(and we now know he literally IS the battery), he and his Corps never lose any energy in battle--a fact Hal notes during their above conflict.
