Although it's called a Tallgeese, it's actually a modified machine that uses more Wing Gundam parts.
Originally a machine made for Gundam Breaker 3, it was made as a personal machine for Einar Broman, an enemy officer who appears in Breaker 2, rather than for my own use.
The machine's name, "Rhadamanthus," is the name of a judge of the underworld in Greek mythology.
Einar's line when he delivers the final blow to his nemesis:
"Continue to burn in the cauldron of hell!"
