This is my first fan-art submitted to deviantart, I'm proud of the results.
Since there are lots of Undertale crossovers, I wanted to create my own, and I remembered Warioware, full of charming and beloved characters.
Mettaton is one of my favorite characters in Undertale, a robot who gave his life to the show and his fans.
Mike, the karaoke machine, another robot who gave his life to the show and loves to perform, I like him too, and his song is pretty catchy. xD
The two are just perfect together!
Well, as always, I hope you like it.
