Spike

Spike is the first seen and playable Titan in Crash of the Titans. He is a hybrid mix between a porcupine and a crab. As his name suggests he has an appearance with prickly, sharp, spines that covers most of his body. Before his introduction was shown he was heard making a terrifying noise that made even Crash trembled with fear. Later he was spotted by Crash and managed to kill three Ratnicians with his special move.

Crash Mind Over Mutant
In Crash: Mind Over Mutant the Spikes appear once again but they seem to be more feral and ferocious looking than before. Crash finds the Spikes in the Wasteland making terrifying noises that frightened the inhabitants of the land. Crash quickly disposes of them and saves the Wastelands. Later they return to Wumpa Island along with the Snipes and damages most of the area including Crash and Coco's Home. From that point on, they're scattered throughout the island.

Trivia

 * This was the Titan that appeared in the Titan Idol video on Youtube, showing how he made it into the game.
 * Uka Uka shares 1 of the same powers as the Spike. Spike pulls spikes out of the ground and then shoves them back down. Uka Uka however puts his fists on the ground and a small area of spikes will come up and then down.
