Not the Last Airbender

Reborn in the world of Avatar as an aristocrat of the Fire Nation, he completely forgets his past life, although snippets of it occasionally surface, prompting him to try and remember. And somehow, he must survive in this war, the reasons for which are unclear to him.

As for how he ended up seducing a princess, gaining a reputation across all nations, and convincing those around him that he is almost the second incarnation of the Avatar, despite only mastering one element, he has no idea. It all happened somehow. Accidentally.
