Magmadon

Magmadon is a Titan that appears in the Crash of the Titans saga. It is a medium-sized mutant that resembles a muscular, bipedal tortoise covered in brimstone. Magmadon is probably the most fiery mutant Crash has ever controlled, and is related to the fire-element. So far it appeared in both Crash of the Titans and Mind over Mutant.

Abilities
The Magmadon is physically the strongest among the medium-sized mutants. This is best described when Magmadon is jacked and strikes a pose, because he stomps the ground two times and causes a minor trembling in the ground. However, despite it's strength, Magmadons are very slow in attacking and (in Mind over Mutant) in motion. They also have much fewer hits during a single full combo, and their hits must be timed carefully in order to gain full potential.

Other than that, Magmadons have the passive ability to endure surprisingly high temperatures, allowing Crash to cross pools of lava or other hot fluids when he's jacking a Magmadon (Aku Aku also stated that the Magmadons kinda like this hostile environment). Magmadons also have high defense, making them capable of moving and attacking undisturbed by some enemies attacking them (they still take the damage).

Attacks

 * -regular attack: Magmadon's regular attack consists of slamming the enemy with a burning fist, and then, on second strike, punch them with the other hand. In both cases, Magmadon incinerates his fists, causing them to glow. This is physically stronger than a usual attack of other titans of the same size, but it is very slow and has only a two-hit combo limit. After both attacks, Magmadon is grounded and it takes time for him to get up again.
 * - block-breaking attack: Magmadon's block-breaking move differs in the two games Mind over Mutant and Crash of the Titans. In Crash of the Titans, Magmadon's block-breaker consists of a powerful body-slam, which is unusual for titans his size because once started, enemies won't be able to hold it off, but it takes time for the Magmadon to get up again, leaving him vulnerable for a while. In Mind over Mutant, Magmadon's block-breaker is simply just a ram with it's elbows, bearing all of the strengths and weaknesses of a regular block-breaker in the game.
 * - Breakdance Raid (block-strike): available only in Mind over Mutant, and executable by pressing the guard button and the attack button at the same time. This causes the Magmadon to lie on the ground and spin around like he's breakdancing. During the period of this attack, Magmadon can't be harmed by regular attacks (attacks such as Ratcicle's Freeze Punks can still effect him, and his health also drops should he strike a TNT crate), but it's difficult to move him around. Magmadon can move very fast while spinning, damaging everything it hits, but the direction in which it moves can hardly be predicted and is based on him bouncing off walls and enemies. The player can press the attack button during this attack, thus causing Magmadon to stand in place while spinning and try to set his direction with the help of a spinning arrow that appears around him. The attack wears off in time or after the player releases the block button.
 * - Hellfire Stomp (special attack): presumably Magmadon's ultimate attack. Magmadon stomps the ground and brings forth a straight line of burning lava in front of him damaging everything it touches. In Crash of the Titans, this is only a straight line, so it has to be positioned well in order to successfully hit it's target, but is powerful enough to heavily damage (if not instantly stun) a big titan such as the Shellefant. In Mind over Mutant, it lacks it's original strength, but has an additional ability to divide in up to three lines to hit more enemies.

Crash of the Titans:
Presumably the very first appearance of a Magmadon is during the opening movie of Crash of the Titans (the one that resembles shadow puppetry). After the scene that symbolizes Crash's creation and betrayal, Dr. Cortex uses theEvolvo-ray to mutate the next thing he sees, which happened to be a turtle, planing to make the mutant work for him and obey him. However, the mutant he created was a skinny creature wearing a turtle's armor as underpants, too weak to even push a rock, let alone fight for Cortex. After making fun of his new creation, Nina snatches the Evolvo-ray, modifies it and shoots at the mutant again, turning it into a much larger and bulkier version that easily lifted a large boulder and rolled it until it blew up. This was probably Magmadon, since both creatures are large, humanoid turtles, which would make Magmadon the first Titan ever to be created. After Nina used the Evolvo-ray on other random creatures, thus creating new titans, the Magmadon demonstrated it's Hellfire stomp ability, only it slammed the ground with it's fist rather than with it's feet. Other titans from the same movie are probably the Battler, the Spike and two unknown mutants, one created out of a bunny, and the other out of a crocodile.

The first time Crash met the Magmadons was at the start of the episode called The Blizzard of Claws. When him and Aku Aku were on their way to reach Tiny Tiger, they came across volcanic soil with lava pools around the area when a group of Magmadons emerged from the ground and the pools. After defeating them, Crash was able to jack one of them and use him to cross a sea of lava in order to reach and destroy the generators for Cortex's drills. The Magmadons were also used later in the battle against Tiny, since they could be used successfully to stun the big Shellefant in order to jack him and proceed further.

The Magmadons appeared a few more times in the later chapters, and Crash could use them to cross over lava or, in the later chapters, pools of liquid metal.

Mind over Mutant
Magmadons return in Mind over Mutant, but in this game, their stats drop drastically, as they are much slower and weaker. They can jump in this game and perform the Breakdance Raid, but they're lousy jumpers and even worse climbers. They can still walk in hot liquids, but there's not much of it for them to walk on.

Crash first sees the Magmadons again in Ratcicle Kingdom, on his way to the prison. Some Ratcicles were seen carrying cubes of ice containing Magmadons for unknown reason. They soon let go of the cubes and fight Crash, but he soon defeats them. After the fight, the Magmadons spring to life, break free from their icy prison and attack Crash, but he deals with them successfully and liberates them of Cortex's control and manages to jack one. The later reappear in other missions.

There is also a Magmadon Hero, who can be found in the secret sections of Ratcicle Kingdom after Crash and Aku Aku free Uka Uka and venture to retrieve his voodoo bones. The hero in Ratcicle Kingdom holding one of those bones is a darker version of a regular Magmadon. In order to reach him, the player must use a Grimly to jump over falling ice-blocks on a nearby waterfall, then walk through a cave filled with hostile Grimlys and Bratgirls, as well as more Magmadons. After he's defeated, he respawns on the same spot and can be jacked.

Worst Titan?
Magmadon is often described as the worst possible titan players can encounter, both as an enemy and as a playable titan, especially in Mind over Mutant. There are walkthroughs that advise the players to avoid using Magmadon whenever possible.

As an enemy, the Magmadons are a real drag due to their high defense, causing them to have no respond to any except the most powerful attacks.

When jacked, Magmadons behave even worse, since they're very slow and very heavy. Their high defense means nothing if the player has to fight a horde of more titans with fast-cutting breath-taking attacks, and due to the power of their usual slams, the Magmadons can only perform up to 2 hits per combo, by which time they'll probably be attacked themselves. This is exceptionally bad in Mind over Mutant, where one such situation can drop the player's multiplier to zero, making it very hard to upgrade the Magmadon. Additionally, they're lame jumpers, making it hard to get the Magmadon at certain spots that are usually easily reachable.

While their Hellfire Stomp is quite powerful in Crash of the Titans, in Mind over Mutant it is much duller. It doesn't deal as much damage as it used to, and should the Magmadon not be positioned properly, there is a big chance of the Hellfire Stomp to sink into the ground before dealing any sort of damage. This usually happens on hillsides and thin areas. Not to mention that their regular attack needs to be timed correctly, otherwise the player will only be able to strike once and then wait for the Magmadon to get up before attacking again.

In order to sustain these fatigues, there is a combo that allows the Magmadon to use it's slow and strong attacks at a maximum rate. In order to do so, attack with both slams (attack, wait, attack), then perform the body-slam (block-breaker in Crash of the Titans, while in Mind over Mutant this is the jump attack), extending the combo limit to 3 hits. You can also jump during the regular attack in order to keep the Magmadon more mobile and having a better chance in avoiding attacks.

On the other hand, the Magmadon's attacks are strong and will leave the enemies stunned for a moment before they can retaliate.

Etymology
Magmadon's name is taken from the words magma, meaning unerrupted lava and referring to their fiery nature, and don, which means teeth and is sometimes used to name certain dinosaurs (such as Iguanodon or Trakadon) referring to the Magmadon's similarities to them, since they're both bulky reptiles. So, literally, their name means "Magma-tooth".

Trivia
Magmadon is physically strongest among medium sized mutants.

In Crash of the Titans, the Magmadon's block-breaking attack is surprisingly useful. Usually, titans need some time to build up their stamina in order to perform one such attack, leaving them open to injure, but Magmadon simply jumps up and is already out of range for other enemies, meaning his block-breaker is a sure shot, although it takes them a while to get up again. The only titan that came close to this is Battler.

Strangely, although the Magmadon's are relatively tortoises, they never used their shells to cover themselves or to hide. In Mind over Mutant, they only find their use when the Magmadon performs the Breakdance Raid.
