Spiker, called Tsun-tsun (ツンツン) in the Japanese manual, is a Badnik from the 16-bit version of Sonic the Hedgehog 2 found in Hill Top Zone. It is a little red insect with a large spiky cone on its head. This enemy is often found walking along the ground, although it can also be seen on the ceiling of caves. Regardless of its location, its attack is the same - As Sonic approaches, it fires its cone upwards if it is on the ground, or downward if it is on the ceiling. The cone is easy to dodge and once it has been fired the enemy is mostly harmless. Just spin attack to destroy it.
The Badnik makes a return in the Wii U/PC version of Sonic Lost World where it can only be found in the 2.5D sections of Tropical Coast Zone 4. They seem to have the same attack pattern from Sonic 2, but now they are able to fire their spiky cones much faster than in the previous game, which can be more tricky to bypass. The player can simply then destroy the Badnik after it loses its spiky cone.
The Sonic 3 enemy Turbo Spiker is evidently an improved model of this Spiker; it moves faster and fires its spike at a slight angle, but its behavior is otherwise identical.
