Brian Calusky, alias the Piledriver, is a member of the Wrecking Crew, who are construction themed supervillain team. At some point prior to his first appearance (presumably during the events in first episode), he was trapped inside a DISK, which then ended up in the hands of Joel Murphy.
When a lost DISK was located on a construction site in Tokyo, Joel Murphy D-smashed the entire Wrecking Crew, including Piledriver, to fight off the Avengers. Piledriver took on both Wasp and Captain America. Wasp distracted him with her size changing powers and speed, so Captain America could attack with his shield. When Chris was seemingly crushed underneath a tower, Cap abandoned the fight to check on him. Wasp however defeated Piledriver on her own, who was then D-Secured in a new DISK.
His DISK was later stolen by Noriko Ashida for Loki, and got lost again after the Avengers' fight with Loki at the latters Ice Palace. At some point after this, all DISKS of the Wrecking Crew once more ended up in Joel Murhpy's hands. When Loki ordered the Celebrity Five to gather the Treasures of Darkenss for him, Joel used the Wrecking Crew to help him obtain the final 2 of these treasures. They first went for the Crescent Dagger, guarded by Wasp and Hulk. Wasp was easily defeated by the four villains and Hulk got distracted when Ed fainted due to a fever. As such, the Wrecking Crew was able to steal the dagger and get away. The team then went for the last treasure, the Solar Crown, hidden in one of the Egyptian Pyramids. This time they first fought against Iron Man, Thor, Wasp and Captain America, but managed to beat them. Hulk and Ed showed up just in time to turn the tides. Hulk engaged all Wrecking Crew members in a wrestling match, and actually proved as strong as all of them combined. When Ed also D-smashed his second hero, Power Man, the team was defeated and once more D-secured by Akira, Chris, Hikaru, and Jessica.
