Seemingly ignoring the man standing a short distance in front of him as he spoke, Akanade lifted his left arm and pointed his index finger at Nickcca. At this point, a small light appeared about an inch away from the very tip of Akanade's finger, and Nickcca would be able to sense a massive increase in energy coming from the Hollow. This burst of energy revealed itself as suddenly a massive wave of energy shot out from Akanade's location and was sent flying towards Nickcca at such a speed where dodging at such a short distance away would be nigh-impossible. This was the Cero technique, a very powerful energy attacks used by Hollows. The energy grew even wider and larger, consuming the entire area in its power, which for a captain class like Nickcca, would be overwhelming.
The massive blast of energy erupted and exploded, destroying anything and everything it came across in the endless desert of Hueco Mundo. This Hollow very clearly wasn't playing around, especially after what he had just used to attack Nickcca with. After the dust began to settle from the attack, Akanade spread his wings out to their full length, which was well over eight feet each. It is very likely a Shinigami like Nickccq may be intimidated by such a sight.
"My name is Akanade Hoja, Vasto Lorde. This is my territory. Leave or suffer the consequences, Shinigami.
