Mega Mechakoopa

Mega Mechakoopa is a larger variant of a Mechakoopa that first appears as a miniboss in Mario Party 10.

Mario Party 10
The Mega Mechakoopa serves as one of the game's mid-bosses. In its boss minigame Mega Mechakoopa's Swing & Stomp, players must ride up elevators and swing on suspensions hanging from the ceiling to jump on the Mega Mechakoopa's head and deal damage. As its health dwindles, the Mega Mechakoopa moves more erratically and breathes fire to try and catch players off-guard.

Super Mario Maker 2
In Super Mario Maker 2, Mechakoopas can be enlarged with a Super Mushroom. They act the same as their smaller counterparts, right down to using jet engines in the Nighttime setting, but cannot be picked up.
