Chao Research 2024: What You Never Knew

"What are the highest Luck and Intelligence Grades legitimately possible for my Chao in the 'HD' version of Sonic Adventure 2 Battle?"

In March of 2024, I asked this simple question upon revisiting one of my childhood GameCube games, having been rereleased on Steam in 2012. I had decided to try my hand at Chao breeding all these years later, only for that single question to drop me into a rabbit hole of information deeper than I ever expected.

... But I would soon find out that there was still plenty of information about this game's Chao mechanics that wasn't readily available, wasn't clearly compiled, or perhaps wasn't ever even documented before.

Two months later, I intend for this video to fix that.
