Department: Montevideo

It was just a normal day in the city of Montevideo; kids frolicking on the streets, adults talking about adult things, businesses working as usual, typical stuff... until, suddenly, something bad happenned: a dangerous tank-type robot called Hakaymono struck in the city, and started to cause havoc, destroying everything in its path. This did not just happen in the town of Montevideo; it happened in 8 of the 19 departments in Uruguay (kind of similiar to states for Americans). 8 robots breaked went haywire and started to destroy everything in their path.

Meanwhile, in the US, Mega Man was living his normal day, assiting Dr. Light in his works. Suddenly, the home telephone started to ring. When he answered it, he heard the President of Uruguay announcing him that he must help Uruguay, due to a rampage of robots breaking havoc there. Mega Man was confused, as he did not know what was Uruguay, so he decided to ask Dr. Light what was Uruguay. Light answered "I do not know much about that place, other than that it looks like Argentina and that it has a lot of countryside. Why are you asking that?" Then, Mega Man told him about the call he had. After the explanation, Light instantly decided to go there.

Not only did Mega Man and Light went there, but so did the usual Mega Man assistants (Eddie, Beat, Auto, etc.), along with Roll, Proto Man and Bass (because Bass reasons).
When they arrived, they met a nice, young robot programmer called Santino Sosa, which would help them in the meantime.

Now, Mega Man, Proto Man, Bass and Roll are going to stop Hakaymono!
