Challenge of Aria-Bellum

The Challenge of Aria-Bellum is an ancient Cybertronian form of fighting, which, if invoked, means two Cybertronians must face each other in single combat. It's so old, even Kup doesn't know about it!

Fiction

Rodimus vs. Cyclonus

When Kup and his crew left Quintessa to find Ultra Magnus and his bots, they were ambushed by Cyclonus. Hot Rod, knowing that Cyclonus would tear the ship apart, hailed Cyclonus, and invoked the Challenge of Aria-Bellum, challenging Cyclonus to single combat, hoping that it would by the others time to figure out a way to ditch Cyclonus. Kup expressed his bewilderment at Hot Rod's invoking a Challenge he had, amazingly, never heard of. Hot Rod admitted he did not know how he knew of it, but he just somehow did. Rodimus vs. Cyclonus

Notes

"Aria-Bellum" is apparently derived from the Latin for "solo combat". This translation is not entirely accurate, as "aria" specifically refers to a musical solo, such as in an opera.
