The X-Burner (X (イクス) BURNER (バーナー), Ikusu Bānā) is one of Tsuna's most powerful attacks. It consists of a blast of Sky Flames from the X-Gloves V.V.R., usable on the ground and in the air. Tsuna was able to perfect it with the use of the Contact Lens made by Spanner. While using "Soft Flames" to create support, he fires the "Hard Flame" forward. Its strongest blast record until the Choice Arc had a strength of 250000+ FV (Fiamma Voltage. Tsuna broke the record when he blasted Torikabuto's illusion with 300000 FV. He did so to save Shoichi Irie, who was the target of the Choice battle, from Kikyo of the Six Funeral Wreaths. Tsuna also used this technique in order to eradicate Byakuran at the end of the Future Arc.
