Some fanfics might have unique Tartarus landscapes. For instance, a fanfic could describe a forest made of bones and thorns in Tartarus where Percy has to navigate. Another unique element could be new powers Percy discovers within himself in this extreme situation, like the ability to control the very essence of the darkness in Tartarus.
One unique aspect could be Percy's relationship with the memories of his friends. Since he's alone, the fanfic could show how he draws strength from the memories of his time with Annabeth, Grover, etc. Also, some fanfics may introduce unique Tartarus - based magic. Maybe Percy stumbles upon a magical artifact in Tartarus that has powers he's never seen before and he has to figure out how to use it to his advantage.
Well, in some Percy Tartarus Alone fanfics, there could be unique interpretations of Tartarus' time - space. Percy might find himself in a time - loop within Tartarus or be able to access different dimensions within it. Also, the way Percy communicates with the long - dead souls in Tartarus can be a unique element. Some fanfics may have him forming alliances or rivalries with these souls, which adds a whole new layer of complexity to the story.
One popular Percy Tartarus Alone fanfic could be 'Surviving Tartarus: Percy's Solitary Struggle'. It might focus on Percy's inner strength as he faces the terrors of Tartarus alone.

Well, in these fanfictions, a recurring theme is Percy's perseverance. Tartarus is full of terrors, but he doesn't give up. It's like he's constantly fighting against the odds.

There's a chance that Percy meets the personification of Tartarus itself. It could be a shadowy, all - powerful being that tries to break Percy's spirit.

One possible plot development could be Percy facing off against Tartarus' own unique and terrifying monsters all by himself. He might have to rely solely on his wits and the powers he has developed over his previous adventures. For example, he could use his water - controlling abilities in creative ways to navigate the strange and dangerous terrain of Tartarus.
Perhaps Percy has to go to Tartarus alone because he believes it's the only way to save his friends. In Tartarus, he might encounter old foes who are now even more powerful.
