Son Goku -Golden Colbat Version-

Quick notice: This version of Goku is essentially weaker than his true form due to the limiter on his head. The thing to take note is that his power is GREATLY limited due to the limiter being created by God. Explained Here
Strength:
Feat 1: Beaten Kougaiji singlehandedly, a demon who not to long ago, beat the WHOLE Sanzo-ikkou team himself.
Feat 2: Ririn, someone who can toss boulders like pebbles and create craters in the ground with casual punches, was matched by Goku several times.
Feat 3: Having been grabbed by Shien (a companion of Homura and is also a god) Goku gets angry and overpowers him.
Feat 4: While in the Tenkai, Goku was chained and shackled. Note that these shackles were as heavy as boulders. He had one on each arm and leg and also one around his neck.
Feat 5: In the "Even a worm" arc, Goku was able to knock out a guy who can take a city-leveling explosion.
Feat 6: Was capable of wounding Homura with his shackles off.
Speed:
Feat 1: Early on in the series, Goku and his teammate were tagging demon at speeds faster than the eye can see.
Feat 2: Kougaiji's first meeting with the Sanzo-ikkou had him going faster than them. Goku matches and exceeds this speed on their second encounter.
Feat 3: Dodges bullets during the "Even a worm" arc.
Feat 4: Homura, the current God of War, was outranned by Goku. (Anime only)
Feat 5: With shackles to each arm and leg and also his neck (each as heavy as a boulder) Goku casually runs around and fights in them.
Durability/Endurance:
Feat 1: Took Kougaiji's flames without any visible damage.
Feat 2: Fell off a mountain. He did break his leg, but was walking on it like it wasn't.
Feat 3: Fell off an even higher mountain later on in the series (yeah, I know...). No visible damage this time.
Feat 4: Severely beaten by Homura. Not even 5 minutes after lying in bed, he was back up asking for food.
Feat 5: Severely beaten by Kougaiji, to the point where he couldn't move a single muscle. After seeing the boy he was trying to save was threatened, he manage to get up and win against Kougaiji. Once his teammate arrived he collasped. Not even a couple of minutes of his teammate and Kougaiji-ikkou fighting, he got up complete recovered and rarring to go again.
Feat 6: During the "Even a worm" arc, Goku was taking bullets, even one that went in his heart.
Feat 7: Naturally unkillable.
Feat: Was able to hang with Homura-ikku for a while before falling.
Intellect:
Since he still has the mentality of a child, he's not entirely the smartest. In battle though, he's pretty smart and reliable. He's been in countless battles since their journey, and is now starting to come out of his shell (he was always relying on his teammate).
Fighting Skill:
He's a straightfoward fighter. Even though he's shown to use head in battles (taking out a horde of demons by destroying the cliff), he's mostly going to fight you without much strategy. Due to his Nyoi-bō, he's versatile even while being straightforward.
Techniques/Powers:
Seiten Taisen - His true form. He can't change back into it unless he removes his Golden Colbat. Once he removes it, it's impossible to get it back on unless you're Sanzo or the Gods who put it on him. Read Seiten Taisen below for power and abilities.
Gear:
Nyoi-bō - His trusty staff. It has an ability to extend to any length Goku wishes. The staff appears whenever Goku needs it.
Seiten Taisen -True Form-

Strength:
Feat 1: Beaten Kougaiji, Hakkai, Dokogakugi, and Gojyo singelhandedly with rather little effort.
Feat 2: Beaten Sanzo, Kougaiji and Homura effortlessly.
Feat 3: Took out a great deal of gods in the Tenkai before being sealed by a higher god.
Feat 4: Erased a demon summoning effortlessly.
Speed:
Feat 1: Not many feats in this department. He runs laps around everyone in the Sanzo, Kougaiji and Homura-ikkou.
Durability/Endurance:
Feat 1: Took a shot in the back from Hakkai's chi blast with no much as a flinch.
Feat 2: Easily blocked a shot from Sanzo's demon banishing gun... a gun that vanquishes demon the moment of contact.
Feat 3: Cannot be killed, even by Gods.
Intellect:
He's a berserker.
Fighting Skill:
He's the "Pokes at a wingless fly" kind of fighter. Even though he can outright kill ANYONE in the Saiyuki world save the ones who can seal him, he's never been seen killing ANYONE. Maybe we can blame that on PIS and Plot No Jutsu, but I guess you can interpret as him being too damn playful. Think Burori.
Techniques/Powers:
None.
Gear:
None.
History:
A kid was presented to the palace in Tenkai from Mt. Kaka because of a particular crime. Actually he was tricked in going there since he thought they would feed him. Kanzeon Bosatsu placed him under her nephew's care and stayed with Konzen ever since. Konzen called him "Goku" after his consistent bugging since according to him was easy to understand and remember for a monkey. He is playful and curious, even brought flowers to his master and folded his documents into paper planes. He became friends with Nataku, but was forbidden to do so.
Goku is born from a rock that contains the spirit of the earth and sky for centuries, making him rich with aura. He was imprisoned in a dark cave made of rock on top of Mt. Gogyo due to a crime he committed in an early age, and his years were frozen there. He stayed there for more than 500 years until Sanzo freed him and let him stay in the temple where he causes trouble to the dismay of the monks. He follows the highest-ranked monk anywhere and was one of the selected youkai by Sanbutusin to accompany Sanzo to his journey to the west.
