Aeroviper (エアロヴァイパー Earo Vuaipā) is a Kaiju that first appeared in Ultraman Gaia episode 32.
Subtitle: Spacetime Monster (時空怪獣 Jikū Kaijū)
Aeroviper suddenly creates a wormhole that sucks Gamu into it. He then takes Gamu into the future and attacks him, so Gamu is forced to make an emergency landing. In this time, Gamu sees Earth become a desert landscape. More shockingly, he finds out that the XIG base was annihilated. As Aeroviper waits for another attack, Gamu begins to remember memories that everyone had. It was revealed that after Gamu disappeared into Aeroviper's wormhole, the Team Falcon had dispatched to attack the beast. The battle ended up with both sides killed (this is can be seen where a XIG Fighter SS and two XIG Fighter SG crashed with the Kaiju's carcasses). A burial was made at the ruined of the Aerial Base with Commander Ishimuro and the whole XIG Team paying them a final respect. Realizing that Gamu can overcome this future and change it, he then starts to battle Aeroviper once again. After his jet crashed, Gamu changed into Ultraman Gaia. Aeroviper's flight ability gives Gaia a difficult time, but Gaia then strikes Aeroviper's horns, quickly destroying them. At this point, The warp hole is beginning to close and warp time becoming unstable, so Gaia then decides the end the fight quickly. He changes into Supreme Version, and by using Shining Blade, defeats the monster. Gaia then rushed into the warp hole and successfully came back.
