Oliver

Oliver is a largely inactive member of the Travelers.

Personality
Oliver lacks confidence in himself and can be complaintive. He was largely passive and did not assert himself in any situation, he also had a domineering mother but this was of unknown relevance.

Given how he gained abilities and the manipulation by the Simurgh, it was difficult if not impossible to grow out of this.

It was largely his job to keep Noelle company when the other Travelers were off base.

Appearance and Powers
Before gaining his powers, he was a short dumpy blonde kid with a bad haircut. Afterward, his face and body shift according to his basic perception of attractiveness, which slightly changes every time he sees a new face to the point that even his friends have had trouble recognizing him. Additionally, he can now become skilled, mentally and physically, at anything he focuses on for an extended period of time.

Throughout his changes, he seems to keep certain basic physical features, such as the blond hair originally had.

His power also lets him impersonate Eden, which was used to great effect in the final battle against Scion. This is due to the Balance vial being the distilled form of Eden's humanity.

Background
Oliver was a member of a professional-level MMORPG video game team on Earth Aleph. He was a back-up man, since his skills weren't exactly up to par.

When the Simurgh attacked Madison, Wisconsin on Earth Bet, she took Oliver along with the rest of the gaming team from Earth Aleph and stranded them on Earth Bet. He did not deal with the effect of the Simurgh's singing well.

Later, Oliver drank half of one of the Cauldron vials found by Francis, with the other half being given to Noelle. Initially, it did not seem to have any effect on either of them, but they both had drawn out trigger events.

After the Travelers became established on Earth Bet, Oliver settled into the role of taking care of Noelle.

Story Start
Was not seen for a long time, and only then in Coil's base.

Post-Echidna
Returned to Earth Aleph with the remainder of the Travelers.

Gold Morning
Oliver was initially left behind by Khepri as she gathered capes from across the multiverse. He later participated in the final battle, where his power caused Zion to briefly believe he might be Eden. This shattered Zion's will to fight and allowed Foil to shatter his defenses with rods imbued by her power.

Trivia

 * Oliver's power is best classified by the now-defunct Shifter classification.
