T-023 Titanium

T-023, code name Titanium (T-023 チタン), is the first of the T-Series robots (T-Series is revolved around chemically enhanced Chaos Energy) that was designed by Dr.Robotnik in an attempt to not only collect the seven Chaos Emeralds but also get rid of Sonic the Hedgehog for good.

Robot Form
Titanium is a metallic-coloured robot with seven thick, cascading spikes on its head pointing upwords. It shares the same eye-style as Metal Sonic  however they are blue, not red. It has a round body and yellow core section, again like Metal Sonic but it has the purple/blue Metamorphisis Emerald encrusted in the center. It has metallic shoulderpads and has huge, bulky arms with rounded fingers and thumbs. This is similar to the feet as it has bulky legs and rounded toes. Its looks can change if it uses the Metamorphisis Emerald to transform.

Super Form
Titanium turns from metallic into a more golden-coloured robot. Its eyes are now red rather than blue. The spikes on its head are warped and distorted from the large amount of Chaos energy in it. It has purple/blue streaks across the sides of its chest. Coming out of its back it has seven energy tentacles, each one attached to a Chaos Emerald. The tentacles' colours vary from what Chaos Emerald it's attached to (e.g green tentacle attached to green Chaos Emerald). The shoulder pads have now become more curved and have curved spikes on each one. Its fingers have now become pointed instead of rounded. Instead of having two legs, it now has four and instead of having normal feet, each leg has a rocket jet, allowing Titanium to fly.

History
Dr.Robotnik had managed to obtain a fake Chaos Emerald that was designed by Miles "Tails" Prower (from Sonic Adventure 2 or Sonic Adventure 2: Battle) and was in his lab attempting to chemically enhance it to make it a perfect replica of a Chaos Emerald, with the ability to activate super forms. While doing this, Orbot and Cubot were trying to catch a rabbit who had managed to escape the Badnik Assembly line and it ended up in Dr.Robotnik's lab. The rabbit then knocked over several chemicals onto the fake Emerald while trying to escape Orbot and Cubot. This caused a huge reaction to occur and blew up the entire lab, however the doctor, Orbot and Cubot and the rabbit survived. When Dr.Robotnik had gotten to his senses, he noticed that the Chaos Emerald was very perculiar. He decided to give it a scan to see what came up. According to the scanner, not only was it a perfect copy of a Chaos Emerald, but it also had another ability. The ability to transform any organic or mechanic being into a perfect copy of any other being in the user's memory. The doctor realised this and grabbed the Emerald. Then suddenly he felt a small twitch and he was shocked to see he had become Sonic the Hedgehog! Dropping the emerald in shock, he reverted back to his original body. He then had the amazing idea of using his new found dicovery to not only get the seven Chaos Emeralds, but also get rid of his rival once and for all! He named his new the discovery the "Metamorphisis Emerald". He knew he couldn't do this himself, so he invented a robot to take care of many of the important steps. T-023 Titanium was created. The Metamorphisis Emerald was inserted into his chest along with a copy of Sonic's data file into his memory. Then the doctor sent his robot out for his latest evil scheme.

In Green Hill Zone, Titanium was hiding in a nearby bush waiting for it's master's signal. Then in a flash, Sonic zoomed past Titanium running as he always did. Titanium got the signal and released a Homing Cage after Sonic. It caught him and took him to the Death Egg as Titanium slowly walked out of it's hiding place. Titanium activated step two and transformed into Sonic, a perfect copy! Then Titanium had to find the Chaos Emeralds. However a nearby Egg Pawn troop had spotted Titanium, mistook it for Sonic and knocked it unconscious. Later, Titanium recovered in a house, however still in the form of Sonic. Then through a door in came Amy Rose. She still thought it was Sonic and was trying to take care of it. Thanking Amy for looking after itself, it secretly swore an oath to make sure Amy was not hurt, under any circumstances. However while still trying to be Sonic and hang out with Tails, Amy and such, it was still after the Chaos Emeralds for Dr.Robotnik. But for every Chaos Emerald it found, it was still unsure about what it's master wanted with them.

Eventually, Titanium had six Emeralds and was still trying to be Sonic. It was with Amy and Tails at the time and Tails found the last one. Dr.Robotnik sent him a message saying to snatch the Emerald and transport to the Death Egg. Titanium obliged, snatched the Emerald out of Tails' hand and disappeared. Confused, Tails took Amy to the Death Egg using the Tornado 2. Titanium arrived back on the Death Egg and saw Dr.Robotnik standing next to an imprisoned Sonic. Titanium reverted back to it's robot form and was about to hand the Emeralds to the doctor when Tails and Amy burst in. The doctor was enraged with this and got out a laser pistol and pointed it at the hedgehog and fox. Titanium noticed this and, trying to keep its oath, knocked the pistol out of the doctor's hand and held him down. Titanium told Tails to release Sonic and leave quickly. Tails confusingly obliged and used the doctor's controls to release the blue blur. Dr.Robotnik was enraged and kicked Titanium off. Sonic and the others realised this and asked Titanium to come with them. Making sure Amy wouldn't be hurt, Titanium agreed, turned back into Sonic and was running with them to escape the Death Egg. Eventually they got on the Tornado 2 and escaped. Titanium has been with them since.

Powers and Abilities

 * Using the Metamorphisis Emerald, Titanium can transform into any living thing as long as it has their data. It gains their looks, voice, memory and skills.
 * Later after being trained by Sonic, Titanium had learned Chaos Control which freezes, or manipulates time. Titanium even came up with the idea of Chaos Shield which creates a gigantic shield of Chaos energy and absorbs energy from other attacks. Chaos Shield can also reflect the energy stored back at the opponent.
 * Titanium has a small jet on its back, allowing it to travel fairly fast if it hasn't transformed.
 * If Titanium has the seven Chaos Emeralds, it can turn into its super form, just like Sonic, Shadow and Silver . It has the ability to fly, move at supersonic speeds and be invincible but all only for a limited time just like the others. Using the Chaos Emeralds attached to its back, it can also fire thin Chaos Spears at its opponent

Weaknesses
If its Metamorphisis Emerald is removed from its chest, it'll be powerless.

Personality
Titanium is usually a very protective robot when it comes to battles and also keeping its oath to Amy Rose, however when nothing serious is happening, it is always trying to be helpful with the other members.
