When Reed Richards finished his experimental starship and wanted to take it on an unsanctioned test flight, his college buddy (and former USAF pilot) Ben Grimm agreed to fly it. Together with Richards' girlfriend Sue Storm and her brother Johnny, Ben and Reed launched into space, where they were exposed to unprecedented levels of cosmic radiation.Marvel Source
The radiation triggered mutagenic changes in each of the four passengers. In Grimm's case, he became a brutish creature with orange, rocky skin. Sue's description of him as a "thing" stuck as his heroic nickname, and Thing became a founding member of the Fantastic Four.
Thing 1.15
Midtown Patrol / Solo / Support build
Updated 24/08:
Nothing new in 1.15. Waiting future Thing changes / revamp.
Equipped Fearsome Fist of Farralah with Pym's to increase DPS output. Switching back to Agamotto on energy / heavy damage fights.
Switch the Strength core to +1 Fighting + 20% sif + 25% health/spirit regen when using medkit. Working like a charm.
Removed 1 point from Endure Assault (should now negate 99% instead of 100%). This change was made because negating 100% disable some item procs, like summon N'garai demon / Hydra Medallion / Jugger invunerability / Cosmic invunerability.
This build is suggested if you are running with full cosmic gear.
