So Charizard only helped save Ash because he hated Aerodactyl, right? I wish we had seen more of Charmeleon though. He evolved way too soon.
Lizardon seemed to dislike Ptera since Ptera knocked him down in the chasm when they first met, although I'm positive that Lizardon was attempting to rescue Satoshi regardless. He was reckless about it as seen when he attacked Ptera with Flamethrower and didn't care that Satoshi got burned, but Lizardon wasn't going to let Satoshi die.
