Transported to the MCU

Nithhogr one of the many protectors of Vroengard, one of the last riderless Dragons, the second biggest Dragon, considered the strongest Dragon alive......... Yet he's powerless to stop the invasion of Galbatorix and the forsworn, fire everywhere dead bodies of riders and Dragons alike and he can't do anything about it.... just watching as his brethren dropped like cattle to the slaughter.......he sensed Mana fluctuations in the air he looked over to see Thuviel preparing to convert every atom in his body into pure energy but it wasn't enough there wasn't enough energy to drive the enemies away so he did the only thing he could do at the moment, link his mind with Thuviel's and give all of his own energy. *ABSOLUTE SILENCE* . .. ... .... ..... ...... ....... ........ *BBBBBOOOOOOOOMMMMMMMM* (A/N - Think of a nuke going off) (P.S. - this is my first time writing something and so obviously constructive criticism is going to be very helpful so please tell me about my mistakes and I will try to fix them as fast as possible.)
