Midgard, as asgardian liked to call earth was a place where they were yet settle in. Even thou Thor had visited N times before calling it home he still didn't fit in well. He was still learning the Electronic gadget which midgardians used to communicate with each other and well other stuff which were now a necessity to him. Being locked up for 5 years dwelling into self-loath he never found his will to explore his new midgardian life. He was homesick; but now he got to call earth home.
He had seen Cap workout couple of times at stark tower what he liked call was gym. Every gym equipment in the stark tower were automatic and were innovated to the best. Thor had never seen anything like that before. He knew it had taken Cap couple of training session from tony to get familiar.
But now Tony and Cap both being gone; he felt hot budding tears stream down his chubby cheeks. He was so sensitive after all that he had lost. He has practically lost everything he cared about; mother, father, Loki, Heimdall and the grief he carried of losing half of the Asgard due to his failure to go for the head. He also needed to gather his shit together and fight thru all odds.
He had sworn to protect Earth way back when he first met, Jane. He had even lost Jane. Even thou it was mutual dumping as he like to put it but still the ache was still there in his heart. Thus now being taken up the responsibility of King of the New Asgard, Thor Son of Odin swore never to lose hope and look this pitiful.
He took off with his new weapon ; Stormbreaker to his destination Stark Tower which was now restored back to its original glory in the memory of Tony by Miss. Potts.
He was determined to turn around the tables; he is an avenger and will always be one.
Thank You
