"Who are you?" He asked.
"The name's Jackson, Echo Jackson."
To say there was an uproar at her words would have been like saying that Gaea was only slightly power hungry. It was a massive understatement. Percy came out in the middle of the racket to find his sister standing in the middle of the chaos with a wicked grin on her face. For a second he could see the Loki in her, before the wicked grin turned into a real smile when she saw Percy. He rushed over to her through the chaos and hugged his twin. He realized that the deck had gone quiet with people watching them. Echo pulled away and beamed at him.
Percy was amazed. Echo was still as tall as he was. For whatever reason, they had always been the exact same height. Must be a Viking thing.
Percy was pulled back into reality by someone asking, "You know the strange girl who just invaded our ship?!" He turned around to find that it was Jason who had spoken. He nodded numbly, and, as usual, Echo jumped in. "Oh Percy knows me really well. I'm his twin sister. Well, technically twin half-sister. Well, more like twin quarter-sister. Well, it depends on how you look at it if you have four parents, but are called a demigod, only half god."
Percy's friends looked even more confused by her explanation, and Percy sighed. Echo was great and all, but she loved screwing people over by messing with their minds. "Echo, these are the other members of the Argo II's crew. Guys, this is Echo, my twin sister." "You have a twin?!" Hazel exclaimed. "Wait, what was the whole part about her being your half-twin and having four parents?" Leo asked.
"Well, Mr. Latino Elf, I am the biological daughter of Sally Jackson, Loki, Thor, and Frey. I was created as Percy's twin by Odin as a weapon and sort of super-soldier," Echo responded. All of the crew looked stunned by her answer. Jason was the first to snap out of his stupor to ask, "So the Norse Gods are real too?" "You bet. And that's part of the reason why I'm here. You see, the Norse god Hel has decided to partner up with Gaea to end your gods and this planet. And I was sent to help you guys fight her and all the Norse monsters she will probably send after you," Echo responded.
"You, are going to protect us?" Frank asked. Echo turned around to stare him straight in the eye, and began to speak. "Listen, Frank Zhang, son of Emily Zhang and Mars Ultor, and remember what I tell you. I may not look like much, and I may make a lot of jokes, but I am the daughter of three Gods, and I have inherited their powers. I am an Einherjer, a servant of Odin, and a dangerous enemy. I have travelled the nine realms, defeated many giants and monsters, died and came back to life, and rebound Fenrir Wolf. I am a dangerous enemy, so do not make me one. Do you understand?"
Frank nodded, a terrified expression on his face. Well, Echo was definitely a force to be reckoned with.
