Intrepid Knight appears as a sub-boss in Arqa Block, found on the 59th floor of Tartarus. It impedes the player's progress and must be fought in order to continue. The Intrepid Knight will use Wind attacks, so Junpei is not recommended. It may also use Hama, so finding a persona that resists/blocks Light attacks can be useful. The Intrepid Knight is susceptible to Rage status, which will raise its attack power, but also prevent it from using skills and causing it to take more damage from attacks. It can also be Charmed, which will make it completely harmless for some time, even though inflicting Charm on it is somewhat hard. Using Persona with Charm Boost and Marin Karin/Sexy Dance, having Mitsuru cast Marin Karin and Yukari attack with Bow of Affection helps tremendously.
The Intrepid Knight appears as a normal enemy in Paradise 8 and 9 of the Heaven area of the Midnight Channel. It will alternate between using Power Charge and Physical attacks. Despite its weakness being Electricity, the damage received from it will be negligible and it will shrug off the damage from All-Out Attacks and Megido skills as well. It will receive normal damage from Fire, Ice, and Wind attacks. If Kanji Tatsumi is in the party or if the protagonist has access to Cruel Attack/Vile Assault, they can deal heavy damage by striking its weakness and following up with those skills instead of an All-Out Attack. If Silenced, it will continually try to use its skills instead of attacking normally. Once defeated, the Intrepid Knight may drop Platinum Reins, 6 of which are used to make the Kijintou sword for the protagonist.
In Golden, it appears in Paradise 5, 8 and 9 in Heaven. It may drop Sphalerite for trade at Shiroku Pub.
