"When it isn't battling, it keeps Dreepy in the holes on its horns. Once a fight starts, it launches the Dreepy like supersonic missiles. Apparently the Dreepy inside Dragapult's horns eagerly look forward to being launched out at Mach speeds."
This Pokémon evolved from a Hattreem which evolved from a Dreepy.
Dragapult is an Dragon/Ghost Pokémon owned by Lexi. She was first introduced in GF045 as a Dreepy, before evolving into Drakloak in GF063 and finally into Dragapult in GF075.
Lexi captured Dragapult as a Dreepy in GF063 when there was an explosion thanks to a Dynamaxed Sandaconda. In the explosion, the Dreepy were sleeping on top of Hammerlocke's Tower, but were disturbed. Dreepy showed much determination and strength in this time, trying to get its fellow Dreepy to safety. However, one Dreepy died, causing the Dreepy to try and take on Sandaconda himself. Seeing his effort, Lexi aided the Dreepy, seeing it was hurting itself in rage. The Dreepy despite in grief, managed to help cause severe damage to the Dynamaxed Pokémon before being knocked out. He was saved by Lexi.
Once the threat was eliminated, Dreepy appreciated the help and Lexi asked it to join her team, he agreed, seeing his fellow Dreepy fly away in happiness.
Dreepy evolved into Drakloak during Lexi's League Battle with Raihan due to its already strong power. He was used following this, and evolved into Dragapult shortly after Lexi arrived on the Isle of Armor.
Dreepy is strong willed and serious. As a Drakloak, he seems cunning and placated, which continued into becoming a Dragapult.
Dragapult is able to use the Dreepy kept inside his horns as supersonic missiles at mach speeds.
