Great, which ones amoung the above is a must watch for a 15year old<|im_end|>

All of the webserials mentioned above are popular among readers and are appropriate for a 15-year-old. However, the content of each story can be different and appeal to different interests.

If the 15-year-old is interested in science fiction and space opera, then "The Last Angel" by Proximal Flame and "The Deathworlders" by Hambone3110 could be a good choice. Both stories are set in space and involve human encounters with alien races.

If the 15-year-old is interested in post-apocalyptic and survival stories, then "Chrysalis" by Eorai and "The Fourth Wave" by Andrew J. Luther could be more appealing. Both stories are set in a post-apocalyptic world, with the former focusing on a single protagonist's journey and the latter following multiple characters across the globe.

"Salvage" by Hambone3110 is a mix of both genres, set in space and involving human encounters with alien races while also exploring post-apocalyptic themes.

Ultimately, the choice of which webserial to read depends on the interests of the 15-year-old. I recommend reading the first few chapters of each webserial to see which one catches their interest the most.<|im_end|>
