#1 Takeover Monday Night Raw

Batista may not be around WWE for a long time. He cannot be expected to stay after the WrestleMania 35 match but still a hefty contract and a good storyline can impress him. After Kurt Angle, WWE needs a nostalgia act similar to him as the general manager.
Batista as the general manager under Shane McMahon would be interesting. The Animal can show extra favor for Triple H's NXT guys who are now his own mercenaries.
Triple H should put Batista over in a huge way. Shane McMahon, on the other hand, should defeat the Miz at WrestleMania and receive a nuclear heat. By some cunning tactics or match stipulation, these two need to take over Monday Night Raw.
This would make the post WrestleMania season interesting with new faces emerging to destroy the alliance of Batista, McMahon and Triple H's NXT recruits.
