So I didn't do a cast but now I can so......

Ksenia Solo as Percy Jackson

Dylan Schmid as Nico Di Angelo

Kaya Scodelario

Alex Pettyfer as Will Solace

Avengers Cast as Themselves

Done! This took forever but I'm so glad it's done! Working on the next chapter but it may take a bit.
Anna Stark

EDIT!!!

So Peter is not here. So Peter Parker is played by Tom Holland (suggested by @NerdyFangirl146 )
