Hobbit

"Stay behind me!"

- Gandalf protecting the hobbit.

A character credited as Hobbit, probably supposed to represent Frodo Baggins, although never recognized this way, appears as a secondary character in DARTH VADER vs GANDALF, the second episode of Super Power Beat Down as Gandalf's traveling companion.

He was portrayed by Maxwell Glick.

Character Traits
The hobbit's personality in the video is similar to how Frodo acts in the beginning of the Lord of the Rings trilogy. He's scared and is not a fighter, although has a powerful will enough to not be seduced by the One Ring.

Darth Vader vs Gandalf
Gandalf and the hobbit are walking within the Shire, when the wizard notices a mysterious figure coming in their direction, and seeing it as a menace, Gandalf tells the hobbit to stay behind him.

The stranger introduces himself as Darth Vader and reveals the reason of his visit: He's there for the One Ring. Gandalf tells him he's not going to get it, and the Sith Lord strikes with force lightning, although the wizard is able to briefly block the attack with magic, as he tells the hobbit to run.

And the hobbit runs and hides, as Vader goes after him, only to face Gandalf once again. After a short fight, the wizard summons a power with his sword, and assumes the young form of his enemy, when still known as Anakin Skywalker. Darth Vader calls his opponent a fool, for not knowing the power of the Dark Side, and is answered with a statement that the ring is more powerful than even it, and it would destroy any good left inside Vader, also calling him Anakin. The hobbit, in his hideout, watches the battle.

Darth Vader whips out his lightsaber, and his young form does the same, the two combat for a while, until Vader's hand is cut off. Gandalf them assumes his original form again and with magic, appears to have defeated the opponent. When the wizard prepares the final attack to knock down the sith lord, Vader uses the force to attrack the lightsaber back to his hand, and with that movement, cuts Gandalf in half, defeating his adversary as the hobbit screams, shocked.

The hobbit leaves his hideout, and Vader tells the Hobbit to give him the One Ring. Submitted by the Force to the Dark Lord's will, the halfling has no choice, and ends up giving the object to the Sith Lord.

Trivia

 * The hobbit is probably the representation of Frodo Baggins.
 * The "NOO!" the hobbit screams when Gandalf dies is similar to the one Frodo screams when the wizard falls to his presumed death in The Fellowship of the Ring.
