Intense Guys is a battle theme in Mother 3. It's normally played when battling against opponents that put up a good fight. It's first played when fighting against an Elder Batty. This composition is rather upbeat, and is consisted of trombones, drums and an organ. It's opening bears some resemblance to the Halloween theme.

Even More Intense Guys

Even More Intense Guys is the harder version. It's pretty similar, but at certain points, a spastic sound plays and the rhythm plays slower. This plays when fighting the Rhinocerocket Mk. 2.
