Armored Ground Spider

The Armored Ground Spider is an evolved Ground Spider made by the "Armored" Black Puppet Princess, remaining underground for its armor to harden while its parents were gathering food for it. The Armored Ground Spider emerged briefly to help its father escape the Oni.

Once fully matured, the Armored Ground Spider was about to take out Roaring Demon & Majestic Breath Demon when Sharp Demon came to their aid, the monster retreated only to be intercepted by Echo Demon before it could kill Josh. It overpowered Echo Demon until he underwent Crimson form, killing the monster with his Explosive True Crimson form.

Prince & Princess
The last parent pair to be created. Because they were created by the armored Black Puppet Princess, they did not have the time limit & thus are the perfected version of Warrior Prince & Armored Princess, armed with a trident & sword respectively. After they defeated Sharp Demon, they fought Majestic Breath Demon & Roaring Demon. Though they had the upper hand at first, the Princess was restrained by Majestic Breath Demon & left open to be destroyed by Roaring Demon's Thunderbol Fist Quake. The Prince escaped, only to later fight the two Oni, before & after Sharp Demon arrives to wound the Prince with his Green Wins before Majestic Breath Demon dealt the final blow with Whirlwind Blade.
