Strifehart

Strifehart is the slash ship between Squall Leonhart and Cloud Strife from the Final Fantasy and Kingdom Hearts fandoms.

Canon
As Squall and Cloud are from different Final Fantasy series, they have never met in canon. Since Squall is from Final Fantasy VIII, while Cloud's is Final Fantasy VII.

While they have never met in canon, they do in the Dissidia series, since they both appear as warriors of Materia, as well as allies in Dissidia (the first game in the series), Dissidia Final Fantasy NT and Dissidia Final Fantasy Opera Omnia. While Dissidia 012 Final Fantasy has them on opposite sides, even though Cloud has fought against his allies and had stood up to Chaos.

Similarities and Comparison

 * The summon monsters featured in their FF games are Odin, Shiva, Alexander, Bahamut, Ifrit, Cactuar and Titan.

Fanon
Strifehart is one of the most well liked Final Fantasy crossover ships, as both Cloud and Squall are trained sword wielding soldiers, even though Cloud is a former one, who have animal head marks. A wolf (Fenrir) and lion.

Some fans prefer to focus on their Kingdom Hearts counterparts in the KH series, since they are two of the first Final Fantasy characters to in included in the series, along with a few other FFVII/FFVIII characters, where they are shown to be allies and possibly friends. The same with their Dissidia counterparts, where the shared scenes of them have gotten a few fans to see Strifehart as a canon-fanon ship.
