Adam

Adam was a very calm, collected, and carefree individual; speaking to Zeus in a very casual manner, much to the chagrin of the other gods present.
We later find out that Adam holds no grudge against heaven, despite the fact the Serpent assaulted Eve and then framed her when he was elsewhere, resulting in humanity's banishment from Eden. However, at the same time, he did not hesitate to kill the Serpent the moment he attacked them.

Adam loved Eve, so much so that he abandoned the paradise of Eden without a second thought when his wife was banished.

Adam displayed selflessness to the highest degree, pushing himself past his limits in his fight against a god to give humanity a bit of hope. Adam's love for his children was strong enough that, even in a battle for his life, he only thought of protecting humanity from anyone who'd try and do them harm.

He was Humanity's representative in the second round of Ragnarok.
