Kamen Rider 27

Unfortunately Diend brought a gun to a knife fight. You'd think he would just shoot the other guy and be done with it, but G Den-O gets in quickly and starts thrashing him good. So he naturally resorts to Diend Combat Procedure #1 and summons a bunch of Riotroopers. G Den-O changes his weapon to a gun, and with help from Eve (who knows everything, including where they all are in relation to him even from behind) kicks their butts.
