Foreman Spike

Foreman Spike was the angry foreman of the construction site where Mario and Luigi worked. Rather than help them, Spike continuously tried to hinder the brothers from doing their job, perhaps to rake in the cash for himself. He is a bearded villain who always wears sunglasses, although in Wrecking Crew '98, he did not have a beard. Foreman Spike is said to be a prototype for Wario and/or Waluigi, much like Pauline was for Princess Peach.

Wrecking Crew
Foreman Spike first appeared in the bonus stages and some phases from the game Wrecking Crew. While Mario runs around in the foreground, Spike runs around in the background trying to outdo the hero. Being already in the background, Spike would not enter doors. While he cannot directly hurt Mario, he will smash down walls, and try to knock Mario off the platform he's standing on which could knock him into an enemy or get him in inescapable area. However, Mario can do the same back to him. He also appears in the later regular stages. Like the rest of the enemies in the game, Spike could only be permanently defeated by trapping him, such as dropping an oil drum on him or knocking him into an isolated floor.

While there was no picture of him in the manual, his ingame appearance showed the same build as Mario and Luigi, a hooked nose, sunglasses, yellowish brown clothing, a beard, and a mouth full of crooked teeth when struck.

He did not appear in Vs Wrecking Crew as his role had been taken over by the second player.

Wrecking Crew '98
Foreman Spike returns in the Japan-only title Wrecking Crew '98. He is the fourth challenger in the puzzle mode game. In this game, Spike is working for Bowser himself, helping the Koopa king build a series of new hideouts. Additionally, Foreman Spike has been redesigned to have a mustache and red nose, resembling Wario.

Mobile Golf
In the Japan-only Game Boy golf title Mobile Golf, Foreman Spike is an unlockable character. He has reverted to his original Wrecking Crew design and is now overweight.

Other appearances and references
The Japanese Super Smash Bros. Dojo website stated that Mario's brown 3P costume in the Super Smash Bros. series is based on Spike's outfit in the original Wrecking Crew for the Famicom. This color choice for Mario would reappear in Super Smash Bros. Melee, Super Smash Bros. Brawl, and Super Smash Bros. for Wii U and Nintendo 3DS, but becoming more black and white than brown and yellow. In Super Mario Maker, one of the Mario forms the player can be is Foreman Spike.

Waluigi's Gold Mantis kart in Mario Kart DS resembles the excavator Spike uses in Mobile Golf, while his signature song "Destruction Dance" in Dance Dance Revolution: Mario Mix is a cover version of the Wrecking Crew bonus stage music.
