Disney Vs Marvel Villains War
On HYDRA Island
The Grim Reaper is initially the right-hand man of Baron Strucker, the leader of HYDRA. When Doctor Doom invades the island, the Grim Reaper tries to stop him from seizing power. Doom's superior magic and technology trounces the Grim Reaper's brute force assault, leaving the Grim Reaper wounded. When Doom emerges victorious, he exiles Strucker and the Grim Reaper from the Island. Only a few loyal troops remained in their service.
Assault Upon the Forbidden Mountains
Strucker and the Grim Reaper then attack the Forbidden Mountains, thinking it weaker without the presence of its leader, Maleficent. Unfortunately, Maleficent's alliance is all too ready to protect the base. The Grim Reaper squares off against Captain Hook, who cleaves clean through the Grim Reaper's scythe. Hades then blasts the Grim Reaper out of the building entirely.
