Threat level: Maoh-, God-
Physical strength: At least continent level striking
Destructive capacity: At least continent+ (Stronger than Kenpachi who destroyed a meteor which would've destroyed Seireitei. Can damage Soul King Yhwach.), likely moon+ (strong enough to do fatal wounds to Yhwach)
Durability: At least continent+ (Full Hollowfied Ichigo snuffed with his hand a Lanza del relampago, which would at least severely damage Las Noches, which is at least a country sized citadel (3 days walk across at least according to Nel's claims), this form is considerably weaker than current Ichigo. Can survive casual attacks from Yhwach.), likely moon+ (can somewhat take attacks from Yhwach)
Speed: At least sub-relativistic (His shunpo in base has augmented x14 times in relation to his shunpos previous speed. With hollow powers he can somewhat keep up with Soul King Yhwach.)
Intelligence: At least above average. While not a genius, he was one of the smartest students in his high school and this without Ichigo actually showing any notable effort regarding studies. Also an experienced fighter with good sense.
Stamina: High. Can fight for hours non-stop, fought for a couple of months straight in his inner world although its uncertain if this would apply in the real world. Has gotten multiple stabs through his limbs in his fight against Yhwach and continued fighting without much difficulty.
Standard equipment: Substitute shinigami representative badge, as a spiritual being he uses his zanpakuto (spiritual blade) which is currently dual swords, one large and one small (previously was a single abnormally large katana). Armor made from material identical to the Royal Guard's bones which is extremely durable. His robes in his bankai are part of his spiritual power
