Character Name: Daniel Walker
Codename: Dimension Walker
Age: 23
Alignment: N/A
Powers: One Time Copy Ability, Training In The Mystic Arts, and Physical Combat Training in various fighting styles.
Bio: Once when he was about four years of age his grandmother was conducting special experiments with portal-like technology when something went wrong and there was an explosion. and when he woke it was assumed he just ended up in another part of town. He was found by Captain America while trying to find his grandmother's lab, which instantly made him suspicious due to the Marvel Heroes being nothing more then comic books.
It was awhile before they realized that he'd accidentally traveled to a new dimension. And even longer when he realized that portals would appear before him at random times.
It was after going to the Daily Bugle to find Peter Parker that he'd found out he could copy any set of powers through physical contact of skin when Peter's Spider Powers were transferred after Daniel swatted his hand away. The Reason he chose to find Peter was due to Madame Web appearing in several of the Spider-Man Incarnations of comics and tv shows in Daniel's home dimension. Though unfortunately, Madame Web couldn't help Daniel, nor could the Beyonder, due to Daniel not being a part of any of the Hero Universes of Marvel, or DC, or any other types of Hero comics.
After traveling through several dimensions it became clear that the one time power absorb ability Daniel had would reset after traveling to each new dimension. He tried to cheat once by touching Rogue and only two possible things ever happened, the first is that due to not having powers yet his life energy was drained away to the point of falling unconscious, and the second, is whenever he had a power it was rendered temporarily drained before coming back the same as what happens with any other super powered being touched by Rogue.
As for his training in the Mystic Arts, he's no where near the level of Sorcerer Supreme, or Doctor Fate, however he can hold his own with various basic mystic spells and the like.
Extra: The only people he's ever opened up to since his adventure dimension hopping began were Peter Parker from Spider-Man The Animated Series' Dimension, Peter Parker from Spider-Man Unlimited's Dimension, And The X-Men Evolution Dimension's Kitty Pryde.

Additional Notes on This Character: Contrary to belief held by some, he can not control The Portals he uses to dimension hop, they simply randomly appear in different locations and he has absolutely no control over them. Further, there are limits to his one time copy ability besides that he's stuck with that power set. Though he can copy the powers completely, he also gains the weaknesses. And if the person the powers belongs to go through new power development he will not be able to gain those new abilities. As for his training in the mystic arts, he's a novice and mainly only ever uses it to create new outfits and disguises for himself on the go.
