Shadow War

The Shadow War commonly referred to as The Stand or Disaster of 2045 was a surprise conflict that began in June 2nd of 2045, where the barriers around Equestria broke, and the forces of evil over came the World of Harmony, destroying everything in its wake, the Evil Invasion eventually stopped at Canterlot, just below the fields, where Rivera and Princess Twilight Sparkle both fought off the Invaders up until the rest of Godzilla Team was able to return and turn the tide along with the rest of the princesses.

The War ended immediately on the day it started just before Midnight, but tragically Rivera of Godzilla Team eventually weakened from his health and eventually passed away a month after the war in July of 2045, in Twilight Sparkle's arms.

Rivera's sacrifice was remembered throughout Equestria as The Stand, where an unidentified artist of Equestria created a portrait of both him and his girlfriend Princess Twilight Sparkle confronting the Invaders.
