Mega Spike

Mega Spike is a larger variant of the Spike that first appears in Mario Sports Superstars.

Mario Sports Superstars
A Mega Spike appears as a boss in the Road to Superstar mode. It walks and hops around, dropping Brick Blocks and Giant Spiked Balls from the sky, and kicking the latter downwards. The Mega Spike can also land on top of an amiibo card, stunning it for some time. When it reaches half health, it gets angry and targets the amiibo cards more fiercely.

Super Mario Maker 2
Mega Spikes later make an appearance in Super Mario Maker 2's version 2.0, being created by enlarging Spikes with a Super Mushroom. They act the same as their normal counterparts, except they throw Giant Spiked Balls, or giant snowballs in the snow-themed levels.
