I find YD persona to be a little funny. In games he's one of the most recognisable and recurring characters and his fight in Megaman 1 is one of the hardest in history.
But in comics? Yucky Dude is a joke, pushed into stories only to fill the quota. He appeared 4 times already, but he was always dealt quickly to focus on more important characters. I actually would prefer if Flynn removed him from those stories and give him time somewhere else (example: use him in Mega Man powered up adaptation instead of this stupid water bot. Or keep Ra Thorn as final boss and leave Ra Devil in case you want to return Ra Moon one day.) Or even make him separate character from Willy.
And what do you guys think?
