Youngblood

Youngblood is a mischievous kid ghost that often plays dress-up and a villain from the Danny Phantom cartoon series.

Pirate Radio
Youngblood teamed up with Ember McLain and sent his undead pirate crew to steal the Fenton's ghost shield and some workout equipment. The plan was to use Ember's music to make the adults come to a cruise that was actually Youngblood's disguised pirate ship. The adults would then be used with the workout equipment to power the young ghost's ship and with all the adults gone, Ember would be able to take over. With the ghost shield, they could prevent Danny Phantom from interfering. However Danny lead the other kids to attack the ship and succeeded in defeating both Ember and Youngblood. The ghost diva abandoned her partner in crime and after the adults were saved, the young ghost's ship was sent plummeting into the ocean with Youngblood and his skeleton parrot trapped via a reversed ghost shield.

Fenton Menace
However when the Fentons drove their sub into Youngblood's ship, Danny panicked and accidentally destroyed the ghost shield generator, allowing him to escape. The young ghost, now clad in a cowboy outfit, continued to haunt Danny in an attempt to make him look crazy since the half-ghost was the only one that could see him. Youngblood continued to pursue him after Jazz convinced her parents to take them on a camping trip to try and relieve Danny of the stress that was causing his apparent psychotic behavior. But the half-ghost managed to get Jazz to get back in tough with being a child by making her have a temper tantrum, letting her see Youngblood. She helped him defeat the young ghost and he was subdued with the Fenton Thermos.

Fright Before Christmas
After Danny headed into the Ghost Zone to try and stop the Ghost Writer, the writer sent him to a Christmas party attended by Youngblood and many of his other enemies. However they welcomed him warmly, much to his surprise, and told Danny about the Christmas Truce, a tradition where ghosts never fought on Christmas. When the half-ghost informed Youngblood and the others that the Ghost Writer was breaking the truce, they angrily went to confront him. At first the writer made them fight each other, but Danny broke his spell by picking up an orange, since nothing rhymed with orange, allowing them to defeat the writer. Youngblood and the others then helped to fix Christmas in Amity Park, which had been ruined by the Ghost Writer.

Livin' Large
As Danny was racing through the Ghost Zone to stop the Guys In White from blowing it up, thus destroying the human world since the two world were parallel of each other, he came across Youngblood, now dressed in an astronaut costume. He was about to launch himself flying with a giant slingshot, but Danny got him, Skulker, and Johnny 13 to help stop the missile the Guys In White were firing, by using the slingshot to launch a boulder into the portal, blocking the missile.

Phantom Planet
Youngblood was attacking Casper High with his undead pirate crew again, but was subdued by Masters' Blasters. Later he was amongst the countless ghosts that helped to turn the planet intangible, allowing the Disasteroid to pass through it.

Powers
Youngblood has the basic powers of a ghost (invisibility, intangibility, flight, and energy rays that he fires from his eyes), along with another unique power, he cannot be seen by adults or kids who have a mind like an adult. In his pirate outfit, Youngblood has a hook that can change into a variety of weapons and a peg leg, that can become a cannon and in his cowboy outfit, his spurs can fire shuriken-like projectiles. He also has an assistant, a skeleton being that changes forms to match his outfits (i.e. a parrot when he was a pirate and a horse when he was a cowboy).

Trivia

 * Oddly Youngblood states his power to not be seen only applies to adults, but it doesn't explain why Tucker and Sam couldn't see him at one point and why Mr. Lancer could see him at another.


 * He often checks with his assistant how to talk to match the various costumes he wears.
