Wizard: I wish I did .
Boomstick: Well , he wields the Bass Buster , an arm cannon that has both rapid fire and charge shot settings .

Boomstick: Which makes the worst sound you 've ever heard in your life ! Make it stop ! MAKE IT STOP !
Wizard: Wily designs and commands his robots with long term strategy in mind and , as a result , often keeps his team as flexible as possible , though this means each robot has specific exploitable weaknesses . As a unit , Wily 's team is prepared for anything !
