- Later in that same episode, Proto Man manages to out-gambit Centum.
- Duo arrives and single-handedly defeats Wily and most of the Robot Masters with him.

- Roll's toaster gun, one of her most popular weapons used in the show, appears at the end of Season 1 when she uses it to vaporize some Stone Bots. She even gives it a proper name, the Toaster Roaster.
- After spending most of his introductory episode being a coward, Top Man finally takes part in a fight with Mega Man... and promptly takes him out with a single well-placed attack.
- Mega Man's aerial chase with Proto Man in "Campus Commandos". Mega Man manages the impressive feat of unnerving Proto Man with a well-placed Armor-Piercing Question, and his character development really shines through in this scene.
