Noteworthy techniques and abilities
==
Tsuna is capable of using the Dying Will Flame (when shot with special bullets or having taken certain pills), which is a form of high pressured energy capable of having destructive powers or purifying evil auras. It initially lies within a person's body until it is awakened, helping increase a person's strength. When a person is able to control the full potential and power of the Dying Will they are able to go into (Hyper) Dying Will Mode at any time. Reborn said that any one has the potential to do this, but not many people can withstand the training phases.
Forms
- Dying Will Mode: This mode is activated when Tsuna is shot by Reborn's Dying Will Bullet or having taken a Dying Will Pill. It uses the pressure he faces during a crisis to externally remove Tsuna's body limiters. He then uses his increased strength and renewed confidence to fulfill his dying will, which is the last thought he regretted before being shot.
- Hyper Dying Will Mode: This is when one has been hit with the Criticism Shot or ingested two Dying Will Pills. Hyper Dying Will, instead of removing external limiters on the body and using pressure during a crisis, removes internal limiters; therefore, releasing the person's hidden awareness. When the internal limiters are lifted, it awakens his Hyper Intuition.
- Ultimate Dying Will Mode: This form is achieved by being shot with a Dying Will Bullet while in the form of Hyper Dying Will Mode. Normally, the Dying Will Bullet would cause you to lose your mental state of mind and only concentrate on what your dying will is; however, in this mode, you keep your mental state and become engulfed in flames.
- Oath Flame: A combination of the Earth Flame and Sky Flame that forms an extremely powerful Flame. This flame has the abilities of both the Sky and Earth Flame and was created when the Earth Simon Ringand the Ring of the Sky Version X fused together.
Equipment
- Sky Vongola Ring: Won after the Ring Battles with the Varia. Tsuna usually wears this Ring around his neck, but he wears it behind his right glove when he is fighting. In the future, both Future Tsuna and Present Tsuna learned how to release Sky Flames with the Harmony characterization. Tsuna is also able to open any kind of Box Weapon using the Sky Flames produced by the Sky Vongola Ring, though the power is less than those opened with the original Flame attribute. In addition, it can also not bring out the true potential of the box weapons. During his battle with Byakuran, a manifestation of Vongola Primo appeared and granted Tsuna and his Guardians the true power of the Vongola Rings. As a result, Tsuna's Flames and techniques have dramatically increased in power.
- Vongola Box Ring (Natsu): After Byakuran was defeated, the Vongola were told that they couldn't take the Vongola Boxes with them. But with Verde's help, the Vongola Boxes were turned into Rings and were brought back to the present with the Vongola.
- Ring of the Sky Version X: A newly formed ring created by combining the Sky Vongola Ring and Vongola Box Ring (Natsu).
- X-Gloves (エクスグローブ, Ekusu guroobu): Created by Reborn's pet,Leon. At first, they appear to be white, wool mittens, but when used with the Dying Will Flame, they change into a pair of black, metal-clad Gloves.
- X-Gloves, Version Vongola Ring: Though otherwise identical to the X-Gloves the Vongola Ring Version Gloves have a large crests resembling the Sky Vongola Ring on the back of each hand.
- X-Gloves, Version Vongola Gear: The new gloves now seem to be mostly red, unlike the previous gloves' black. The normal crystal blue Vongola Emblem in the middle now has a red cross on top of it reading "Vongola Famiglia," and Flame type designs cover the bases of the gloves. Also, as part of the gear, a leg bangle has been added. This bangle is similar to the Ring of the Sky Version X, as it is connected by a chain to a simple belt with an "X" as a buckle.
- Flame Resistant Clothing: These are spun from special Flame Resistant Cloth made by Leon and are capable of withstanding the Dying Will Flame to an extent.
- Contact Lenses: Created by Spanner, these Special Contacts display a targeting system, as well as a system to gauge the strength of the Flames in both X-Gloves. Using these Contacts, Tsuna is able to maximize the power of the X-Burner without propelling himself. The Contacts are apparently interfaced with his earphones.
- X-Headphones: Created by Giannini during the Future Arc, as a method of communication during the Merone Baseinvasion. Per Reborn's request, this headset is able to project holograms to allow Reborn to help Tsuna from a distance. Spanner later linked the headsets to the contact lenses he created to help Tsuna perfect his X-Burner. The present Spanner created upgrades for these along with upgrades for the contact lenses.
- Lancia's Boss's Ring: Lancia gave this Ring to Tsuna before the latter left with Basil for Italy. Tsuna brought it with him to the future, and found out that it was a special ring until it was detected by a Strau Mosca shortly after meeting Lal Mirch. It also protected him from Byakuran's Mini White Dragon.
- Motorbike/Airbike: In the manga, Tsuna has a Honda 250cc NSR Rothmans. In the anime, the airbikes have identical appearances aside from differences in coloration, so Tsuna's color is primarily white with some blue.
- Leone di Cieli Version Vongola (Vongola Sky Lion): Tsuna's Vongola Box Weapon, which takes the form of a young lion with a mane made of Sky Flames.
- Cambio Forma Modo Difesa (Mantello di Vongola Primo): Through Cambio Forma, Natsu changes into a long, black Cloak. The Cloak is attached to a metal plate on the X-Gloves. The Cloak's Ability is to nullify attacks using the Sky's Harmony characterization.
- Cambio Forma Modo Attaco (Mitena di Vongola Primo): Natsu combines with the X-Gloves and turns into a Gauntlet. While using this, Tsuna can concentrate all his Flames into a single attack without charging.
- Leone di Cieli Version X: This is the Vongola Gear version of Natsu, Tsuna's Vongola Box Weapon. With the upgrade, Natsu has armor on his legs and is wearing armor with the Vongola crest on his forehead. Natsu is capable of merging directly with Tsuna for the latter's Cambio Forma.
- Version Vongola Gear: Natsu fuses with Tsuna and his Vongola Gear X-Gloves and turns into flame-patterned arm thrusters. These thrusters can be used to support the XX-Burner or emitFlames powerful enough to escape the gravity of a black hole.
- Modo Attaco (Attack Mode: Vongola First's Gauntlet): Natsu fuses with Tsuna's right Vongola Gear Glove and turns into a gauntlet used by the first Vongola Boss.
