Highlander: Takemikazuchi

Gigant: Take-Mikazuchi is a form of satellite. According to Continuum Shift, it was sealed away after the war due to fear of its use. Despite this, the satellite was still activated and had fired upon Kagutsuchi in Calamity Trigger. From Rachel's words, it seems as though Take-Mikazuchi can only fire once every four years. Take-Mikazuchi is a Japanese thunder god and patron saint of warriors. Because of the fearsome and dark appearance of the spirit stored within the satellite, it is commonly mistaken to be the Black Beast itself.

The weapon first appears in the opening to Calamity Trigger, where it fires upon the 5th Hierarchical City of Ibukido and destroys the facility where Mu-12 is being tempered. In one timeline, this act kills her, but in another timeline, the one in which BlazBlue's story mostly takes place, she survives but has no memory of the incident.

In Chronophantasma, Take-Mikazuchi is the final boss in Story Mode, summoned from space by Izanami. Since Relius has opened all the Gates, causing the surface to be much thicker with seithr, it can now fire as and when it likes, rather than once every 4 years. It takes Jin, Noel and Ragna with his BlazBlue activated to defeat it.

In the story mode gameplay, the player plays as Jin first, followed by Noel and finally Unlimited Ragna. It is a fearsome opponent to defeat, having attacks that are sudden and possibly unblockable, and has Izanami frequently backing it up with attacks of her own. In Overdrive state, Izanami summons three purple homing energy spheres as well as two portable turrets, similar to Mu's Steins Gunner, firing in quick succession at the player, but can be destroyed (slightly difficult since they move after firing before almost immediately firing again). The huge beams which Take-Mikazuchi usually fires are its two Distortion Drives, but both can be fully avoided. Moreover, it also has an Astral Heat of its own, in which Izanami summons a red beam from the ground, before multiple blades, similar to Nu's, are shot upward where the player is then trapped by chains with blades and then fired upon by Take-Mikazuchi. At the end of the story mode, a new mode is unlocked which allows the player to fight Take-Mikazuchi again but with any character.

In Phase Shift 2, while Hakumen fought the Black Beast to protect Celica, Konoe used it against the Beast to drive it away from her sister.
