Aizen's power is just plain illusion. Gremmy's power can actually convert those to reality. Both are different. For eg, aizen can make an illusion of lava and use it as a cover for his actual attack which is usually physical one. Gremmy on the otherhand can actually create it and use it to attack. So it won't be same as aizen's. Gremmy's power was so overpowered (it was like putting a mini- Kubo in bleachverse)limit on the power was necessary, to be logical. Or else, Yachiru would have to keep on living with cookie bones.I hope kensai and rose are alive now that Gremmy is distracted.
