Character under, over, or just right powered???

[Orguss]

Moving through walls on a high roll is silly. As you can pretty much get out with a high roll to begin with. Allowing to move through walls on a roll of 1-3 is much more beneficial.

Also, while your abilities may not be overpowered, there is no centralized theme to tie them together other than the names. Which really don't even work well on that aspect.

Something you should try is

2 wounds

STEALTH - May walk through a space with a zombie and try to VANISH. If you successfully VANISH, you may keep moving.
VANISH - May cancel a zombie fight on a roll of 3+ on the hero turn, or 5+ on the zombie turn
DEFLECT - Any time you would take a wound, roll a D6. On a roll of 5-6, a zombie in your space takes that wound instead.

So, two abilities tie him to an agility run and gun style of character. While both being pertinent to the theme of the ninja, and the last ability is a way to keep his 2 wounds going strong and can cause some shenanigans with cards that cause self-inflicted wounds, or zombie cards that give you a negative choice or take a wound.

Also, with Stealth, you basically have the walk through walls ability. A zombie is blocking the door? I walk into his space, hide, and keep on moving.
