Demon Candy: Parallel/Awesome

A webcomic based around bondage can't be awesome, right? Think again.

Unmarked spoilers ahead.

Jonathan gets an awesome moment early on in the story, right after meeting Victoria for the first time. He immediately attempts to retrieve his soul by trying to punch her out. It fails miserably, but taking on one of the most powerful demons in existence with just your bare fists takes serious balls.
Another one for Jonathan and probably his best so far is during the duel for Victoria's throne. Lilith has revealed her plan to torture Caley in order to force Vicki to give up her crown. Just when Vicki is about to fold, Jonathan (In Joani form) takes the bullet for Caley, offering himself in her place. Lilith's whip can't leave a mark on him and she loses, then Joani taunts her by saying what a crappy domme she is.
Victoria herself shows her stuff shortly afterwards, using a contractual loophole to seize ownership of Caley away from Lilith forever.
It's subjective, but the ending of the Dangerous Games chapter might count. Jonathan has been put through an absolute wringer of bondage devices and enforced role play, only to be confronted at the end with what appears to be an image of himself freed from all inhibitions. His denial is broken and he descends into subspace, but is yanked back to reality by the sight of his soul. After undergoing a traumatic Heroic BSOD, he claims to Vicki that he isn't finished yet, and will definitely reclaim his soul no matter what.
