About me:
Shiva is introduced as a carefree, proud, and powerful God. However, he has shown violent tendencies, even against Zeus himself but stood down in respect of his senior. This is further reinforced when he boldly became shocked by what his opponent thinks of Ragnarok, stating that it is the best event.
In his youth, Shiva was far more lazy and easygoing. Almost every serious thing he did, was through following his best friend, Rudra, while he actually enjoyed to sleep and dance, so much that he wished to become a God of Dancing. However, he did say he always has fun with Rudra, so he is fine following after him.
Once he and Rudra finished fighting their way to the peak of Svarga, he shows a lot of compassion towards Rudra, trying to change the subject to not fight him and begging Rudra to give up so he wouldn't have to harm him further. In the end, Shiva tried to pretend to act defeated so he could stop the fight and make Rudra happy to think he achieved his dream. However, when Rudra scolded him to give it his all and made him see he really got to the peak of Svarga, he finally accepted the title of leader of their pantheon.
He states in his round that he won't lose to anybody and that he isn't going to let Rudra and the people cheering on him down.
Vishnu does comment that Shiva is always reckless while Rudra replies by stating that while he (Shiva) is nicer than anyone, once he get into a fight, he enjoys talking with his fist more than anybody else. Varuna also comments on how Shiva doesn't stop smiling, no matter how many times he gets hit, and Agni states that Shiva doesn't know the meaning of restraint.
