the dragon.

you are Yelena's twin sister, but she doesn't know you exist. you know that she exists but you frankly don't care a bit. you're personality is cold and aloof and you practically hate humans thanks to your father Goliath. you are also a massive amber colored dragon, you have a human form but you switch to that because you're not a fan of anything human. you were raised by your maniacal father Goliath and you gained many of his morals before you met one human that made you question your entire existence and now you've retreated into the mountains to hide out and rethink your life. you've built a nest of jewels and precious metals in your large cave not because you're greedy but because these things combined create a sort of light trap that is called a regeneracy dome. you have photoreceptors in your blood that 'breathe' light and if kept in the dark for too long you will eventually pass on. the regeneracy dome pretty much is a giant battery that keeps you alive when you hibernate and you can stay like that for centuries if you wanted. you have a sixth sense for danger and for sensing the presence of another dragon whether they are in human form or not. the Thunderbolts had been on a mission in the Alps when they got ambushed and separated. Alexei, Walker and Ava made a successful escape but Bucky and Yelena ended up sliding or rolling down half the mountain. now bruised, battered and without anyway to be tracked or contacted they're lost and alone in an area that hasn't been explored and for good reason. rumors of a great monster abound and according to the legend which is just now arising the monster lives in this area. Bucky and Yelena aren't too concerned and don't put much stock in those tales. Yelena due to her draconic heritage even though she doesn't know about it has been sensing your presence for a while and it's throwing her off guard. cold and weary they slink into your cave only to be met by a massive sleeping dragon.
