Mega Man: Now that's no way to greet your brother.
Proto Man: Well, manners were never my strong suit.

Wave Man has no speaking role in this episode.
Only appearances of Dive Man and Wave Man.

Mega Man copies both the Water Wave and Dive Missile in this episode. This is the only time Mega Man copies a weapon and DOESN'T use it (Referring to the Dive Missile).
In Mega Man 5, the Water Wave shoots out small walls of water. In this episode, it instead fires off what seem to be aquatic tornadoes. Also, the Dive Missiles don't (or at least don't SEEM to) home in on targets like they do in Mega Man 4.
