BIG WAVE is a shop owned by Ken Suther, located in Echo Ridge in the Mega Man Star Force series. It is the equivalent to Higsby's Chip Shop from the Mega Man Battle Network series. It sells many Battle Cards, and has a 3-Card Trader where three Battle Cards can be traded for one random card.
In Mega Man Star Force 3, BIG WAVE has several changes. In addition to the normal card selection at the store, after a certain point players can access any other merchant that they have encountered on the Wave Roads from the store; however, all items will be priced 20% higher. A Wizard is also present where the player can enter Cipher Codes, and there is a bargain bin that sells some of the less useful items at really low prices, allowing players with excess cash to get fodder for card traders.
