Imagine you knock a girl up, run away with the baby, then drop off the baby at your cousins house that you haven't seen since you were a child.
Then you run away and make some video game and claim that it was all for your son to play some day. When your son actually beats the game the reward which he thinks will allow him to finally see his father who was missing for 12 years instead takes him to your friend who doesn't even know where you are.
Then after your son helps save the world and recovers from near death illness,(which you never even visited while he was on his deathbed) rather than just being a nice guy you tell him see that huge tower that you could very easily die climbing, if you climb that then I'll let you talk to me.
What an arrogant piece of shyt. We've got fathers in this world we go around calling deadbeats because they don't pay child support and sometimes miss a weekend with their kids. Meanwhile this guy disappears for 12 years because being a Hunter is dope AF. It's not like he's out there being a Hunter making loads of cash so that Gon could have a better life. Nah, he just thinks it's really fun and doesn't want to give that up.
Ging is the worst father EVER
