In his youth Thor was brash, arrogant, boastful, immature, irresponsible, headstrong and hot-headed. After spending time on Earth, he matured to the point of being responsible and developed a sense of humor. After the death of his father and his sister destroying Mjölnir, he was greatly humbled, though he remains confident and brave. #Thor #ThorOdinson #GodofThunder #ChrisHemsworth #MCU #Marvel #Avengers #NorseMythology
