"Make no mistake. It is not revengeance that motivates me.
I exist only the serve GEATHJERK Supreme Overlord Jergingha.
If my brother had done the same, he'd still be alive now."
― Walltha making his motivations clear, Operation 005-C
Walltha is a third-class officer of the GEATHJERK Federation Supreme Armada, and one of The Wonderful 101's main antagonists. Like his twin brother, Laambo, Walltha is a bloodthirsty and merciless warrior, and although he prefers to fight from the safety of his custom mech, Wallgah-Goojin, Walltha is equally as dangerous as his brother when forced to fight his enemies himself.
Walltha makes his first and only appearance in the game as the boss of Operation 005-C.
GEATHJERK File[]
Third-class officer of the GEATHJERK Supreme Federation Armada.
Twins with Laambo, he is even more violent than his brother. The two have committed countless crimes from planet to planet, and their infamy is known throughout the universe.
Like his brother, war is Walltha's reason for existence. Walltha's tactics always involve sending his command unit, P-3800, rushing straight toward the enemy. This unit is composed of some of the best fighters in the GEATHJERK army. Owing to the savage tribe he comes from, he is bloodthirsty and merciless and feels no anguish for losing allies in war — even his brother.
He uses a tuned-up custom version of the bipedal assault weapon Gah-Goojin, fighting beside his troops on the front lines. Watching how happily he annihilates everything in his surroundings is said to bring terror to even his fellow GEATHJERK officers.
Description[]
Appearance[]

Walltha is a monstrous humanoid alien from planet Doquuzu with reptilian features, including four eyes, black scales with a blue underbelly, clawed hands and feet, a hulking, hunched over posture with a billowing mane of blue fire running down his back and engulfing the tip of his tail, and rows of sharp fangs spilling out from his mouth, causing him to roar and snarl constantly as he speaks. As twin brothers, Walltha and Laambo are almost identical in appearance, aside from their colors and a short "beard" of flame around Walltha's chin.
As a high ranking GEATHJERK officer, Walltha dresses in a formal-looking dark blue and gold-trimmed uniform resembling the service dress uniform of a US Navy Officer. Walltha's uniform includes a grey necktie, spiked black shoulder pads and bracelets, and various award medals and lanyards. Walltha also wears blue sunglasses over his eyes and a service cap with its visor angled down, covering his face
Walltha is armed with an unnamed energy sword similar to Laambo's Dechno-Bo, but with a thinner blade and a large, spike-covered hand guard. The color of the blade indicates Walltha's health, and it changes from blue, to green, to orange, and finally to red as he takes damage. The sword itself can also be damaged and will start to show cracks until it finally shatters, which stuns Walltha until he eventually recovers and reforms the blade.
Personality[]
"Funny. Your bro said the exact same thing.
[...]
You might not care about your bro like most people do, bro, but think of it this way:
We're giving you a chance to make it up to him... in hell!"
― Wonder-Blue telling off Walltha, Operation 005-C
Walltha is extremely similar to Laambo in terms of personality, to the point that they both repeated some of the same phrases during each of their encounters with the Wonderful Ones. However, unlike Laambo, who constantly throws himself into the front lines of combat, Walltha seems to value his personal safety as a high ranking GEATHJERK officer, and he instead prefers to do all his fighting using his personally customized Gah-Goojin, Wallgah-Goojin. However, when forced to fight his enemies up close, Walltha is still just as dangerous as Laambo.
Despite being twin brothers, Walltha showed no concern for Laambo's well-being, as he instead considers himself to be entirely dedicated to serving Jergingha. Walltha even derided Laambo by blaming his death on his lacking loyalty to their Supreme Overlord. Because of his past, Wonder-Blue seemed particularly upset by Walltha's lack of compassion for his brother, and the Wonderful One wasted no time berating the GEATHJERK officer over this behavior.
Gameplay[]

Walltha is encountered as the main boss of Operation 005-C: after securing Mt. Ogretoe's Super Reactor, the Wonderful Ones attempt to leave the area using their newly hijacked Gah-Goojin, but are stopped by Walltha in his much more powerful Wallgah-Goojin, and what follows is a giant-robot boxing match against the GEATHJERK officer that the Wonderful Ones must win before they can escape the volcano.

Walltha is also fought directly as a mini boss enemy during Operation 005-C, and he also reappears in Operation 101. As a recolored Laambo Laambo's brother, Walltha possess the exact same abilities as Laambo, and all the same strategies for fighting Laambo also apply to fighting Walltha.

Trivia[]
- Not only do Laambo and Walltha share the same voice actors (Bob Joles and Yasuhiko Kawazu,) but they also reuse some of the same voice lines.
- Walltha's name is derived from "悪さ (warusa)", the Japanese word for badness.[1]
- Walltha's name is also a reference to the firearms manufacturer Walther, hinted at by the number of his command unit, P-3800, a reference to the Walther P38, one of the manufacturer's most famous firearms.
- Walltha's "Make no mistake. It is not revengeance that motivates me." quote is a reference to Metal Gear Rising: Revengeance, another game by PlatinumGames that released on the same year as The Wonderful 101.
- Walltha's concept art refers to him as Laambo's "アニキ (aniki, big brother)" rather than his twin.
- Laambo and Walltha are partially based on the "Red Oni, Blue Oni" character dynamic, where two related characters come into conflict over their opposing personalities. In this case, Laambo represents the hot-blooded Red Oni brother, whereas Walltha represents the more responsible Blue Oni brother. The "Red Oni, Blue Oni" character dynamic is a common trope in Japanese storytelling, with some other examples including Dante and Vergil from the Devil May Cry series, and The Wonderful 101's own Red Oni and Blue Oni Wonderful Ones.
- Walltha and Wanna are the GEATHJERK Officers with the fewest appearances in the game, as they're both only encountered once in The Wonderful 101's Story Mode.
- With Wanna's return in The Wonderful One: After School Hero, Walltha is now the only GEATHJERK Officer to only appear once in the game.
