I think it's not Ichigo who produces the Gran Rey Cero, I think this is the work of his hollow side (White Ichigo, Hollow Ichigo, Hichigo, Shirosaki, Zangetsu {so many names}) he just gives the power to Ichigo to wield kinda like Zangetsu (Juha Bach, Yhwach {seriously what's with the names?}) who gives Ichigo the power to use the his zanpukto in Shikai and Bankai, with his permission, this expressed the filler episodes where Muramasa takes control of zangetsu, Ichigo tries to use Bankai however zangetsu tells him you don't have my permission to use, same way Hollow Ichigo allows him to use his Hollowfication, this due to the fact that Ichigo is not a hollow, he just has an inner hollow, (kinda like demonic possession in horror films, the person who is possessed is not a pure demon, they are possessed by a demon within or near their souls), However this makes another Question: If only arrancars can produce "Gran Rey Cero", why can Ichigo and his "normal hollow" can do the same thing. This is where my theory comes into place, my theory is that Hollow Ichigo may not be a simple hollow, he may be a Vasto lordes. There are my reasons

1) During the battle with Isshin and Masaki vs the "Devil Horned Hollow", the hollow in this scene was much smaller and more human-like than the hollows you see in karakura town, this may be because he is a Vasto lordes or somewhere around the lines

2) During the final battle with Ulquiorra, Ichigo disappears and reappears, "That wasn't a flash step he just used, it was a sonido" quoted by Ulquiorra himself, and if you paid attention you would know that different factions have their own version of Shunpo	Soul Reaper's: Flash Step	Visards: Flash Step	Quincy's: Hirenkyaku	Fullbring's: Unnamed	Arrancar's: Sonido During Rangiku's battle with Nakeem Grindina, Nakeem explains that just Flash Step, Sondio is an official Arrancar Technique, which is something Ichigo could do, and it was explained THAT ONLY ARRANCARS CAN USE IT, however, Ichigo could in his hollow form giving to more reason to consider hollow Ichigo an Arrancar

3) Another instant where someone actually considered Ichigo being in an Arrancar, was his first battle with Ulquiorra (the one that took place before Ichigo's final fight with Grimmjow. Ulquiorra quoted "It's like he is one of us", this when Ichigo activated his hollowfication. Giving more reason to consider Hollow Ichigo being an Arrancar

4) Another reason is Hollow Ichigo's personality and behavior, let's start with his behavior, during the anime series we see Hollow Ichigo as a ruthless merciless psychopath, most arrancars shared the same traits, I know arrancars are the antagonist, which makes it reasonable for them to madmen and women, but however Hollow Ichigo is much worse, during Yammy and Ulquiorra's arrival in the world of the living, one distinctive line that struck a chord in me is when Hollow Ichigo says "SWITCH WITH ME", now this could be a double-edged sword, maybe he knew Ichigo alone wouldn't stand a chance against them or maybe he who or what they were, because maybe in hollow ichigo's previous life he MAY have been an Arrancar. His personality is another factor to consider, during the series Hollow Ichigo talks about "Instinct", who uses instinct? animals, and if you look at arrancars they sorta resemble a specific animal, Grimmjow is a feline, Ulquiorra is a bat, Coyote Stark is a wolf, Noitora is kinda like praying mantis, lumpy is like an octopus or squid and Hallibel has shark characteristics

Now i believe that Hollow Ichigo is no ordinary Arrancar, I know this from when Masaki gave birth to Ichigo the hollow which possessed her moved into Ichigo, and when Ichigo got his powers awakened from Rukia, just take note this when Rukia still had the hogyoku within her, and if you know what the hogyoku does, it can fuse hollows to humans and give hollows the power to remove their masks to become arrancars, this may have affected Ichigo as he now has a much stronger bond with his Hollow side, and his hollow side was able to remove his mask to become an Arrancar.

This is my explanation of why Hollow Ichigo is an Arrancar and also why Ichigo was able to discharge a Gran Rey Cero

P.S, this is only a theory and this MAY not be true so don't take things WAY TO SERIOUSLY, because I'm an only theorist and not the producer or author of bleach
