The Spiker (ツンツン,Tsun-tsun?) is an enemy that appears in the Sonic the Hedgehog series. Spikers are small Badnik models created by Dr. Eggman which they are usually moving around slowly and launch their large spiky cones once the player encounters them.
The Spiker's main body appears to be a simple, red round ball which is almost identical looking in comparison to the Gohlas'. The Spikers also have yellow spider-like leg walkers on the bottom of their body and they wear a headgear on their heads that is a large spiky cone. In Sonic Lost World, they have small antennae on the orb-shaped body and cyan colored pupils.
Sonic the Hedgehog 2
In Sonic the Hedgehog 2 Spiker is found in the volcanic caverns of the Hill Top Zone. These enemies are often found walking along the ground, although they can also be seen on the ceiling of the caves. Regardless of its location, its attack is the same - As Sonic approaches a Spiker, 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 Spiker will be mostly harmless and easily destroyed with basically any attack.
Sonic Lost World
Spiker Badniks make a reappearance in the Wii U/PC version of Sonic Lost World, where they are only seen as enemies in the 2.5D sections of Tropical Coast Zone 4. During the game, it turns out that the Badniks, including Spikers, got hijacked by the Deadly Six.
In gameplay, the Spikers have the same attack pattern from Sonic the Hedgehog 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 this Badnik after it loses its spiky cone.
Powers and abilities
The Spikers' main weapon are the large spiky cones on top of their head. When an enemy is in close proximity, they can fire their spiky cones through mid-air at the opponent, both upward and downward. They are also excellent climbers, being able to hang effortlessly from the ceilings.
Spiker is also seen in Sonic the Hedgehog Yearbook 1992 story "Space-Hedgehog" as one of two Badniks with Rexon to threat Sonic the Hedgehog and is firing its cone directly at him. It is then seen holding the frozen Sonic out of a hole, but gets later destroyed by Sonic after getting free and using Spin Attack.
