The main character, Kratos, is a demigod, along with his brother, Deimos, being the sons of Zeus and Callisto. Like another demigod, Hercules, Kratos eventually ended up becoming a full god himself, but in Hercules' case it only happened in mythology.
In Greek mythology, Kratos is the divine personification of strength, the son of the Titan Pallas and the Okeanid nymphe Styx.
Then he serves the Gods for 10 so by the beginning of original GoW he's already 48. Gonna just consider that all events from GoW, GoW2 and GoW3 span over a period of 2 years so he's at 50 by the end.
The number of Norse gods that physically appear and interact with Kratos and Atreus can be counted on just one hand (Mimir, Freya, Magni, Modi, and Baldur), or two hands if one also counts Atreus being Loki and Thor's brief appearance in the secret ending.
Even though Deimos was younger than Kratos, he looked older than his brother because Kratos hadn't visibly aged since he became a God, and Deimos had a beard compared with Kratos' smaller goatee. Deimos appeared as an alternate costume for Kratos in PlayStation All-Stars Battle Royale, through pre-order DLC.
While Zeus was the Strongest Being in the Greek Pantheon, millenia even before Kratos's Birth, Kratos's spartan upbringing made him significantly strong which in turn magnified his Demigod powers through many combat attributes.
As far as Odin Goes, Odin is on a super high power level even compared to Thor but his feats are currently unknown. In GOD OF WAR Franchise he is powerful enough to obliterate even the one above all of marvel. And if you are asking about thor of GOD OF WAR universe, then yes. Kratos will kill him, no doubt about that.
There need to be certain additions and changes to Atreus' characterization and role in the plot in order to have fans fully embrace him as the next main protagonist in future God of War games.
It is implied that he has an intense fear of Kratos as well like how Zeus had, however unlike the Olympian he knew nothing about him except that he is extremely powerful, having faced and killed Modi, Magni, and Baldur. In addition, Odin jealously guards all the knowledge and secrets he collected.
