His most favored type of combat was to be teleported over top of the enemy and dropped on them unleashing a single, immense punch charged with Shocking Fist, Power Attack, and anything else I could think of. DM let me add falling damage to the punch, which helped out to encourage causing myself to almost die every fight.
Highlights include grappling and Tombstoning a Spellweaver Lich into a pit full of spikes, growing to huge size and fist fighting an undead deity's archon in a zombie-shark tank, and being teleported 200 ft. in the air over an Overwurm and unleashing a single fully powered up Shocking Fist, Power Attack, additional falling damage mega-Panch literally the entire length down its esophagus and into its stomach instantly killing it.
He was based on The Iron Giant.
Our party died while defeating the BBEG minor deity and as I delivered the final haymaker, I whispered 'Suuuupahmaaan...' in midair.
There is a statue of me in the town we saved made of Mithril and Silver.
