I do not have intellectual property over the character, neither any name exposed on this page.
Buff McStrongmuscles is an average child in the post-apocalyptic future filled with bombs and radiation and all manners of nasty things. One day he wandered into a cave and found a rune which suddenly awoke his dormant nature as a half-vampire-ghost-chimera-cyborg-demon-god.
But Buff's power came at a price as he could only live alone from that point onwards: a street thug was paid 5$ to kill his parents, which he did. Before his passing father and mother, Buff made the thug pay as he was bestowed his parents' powers in their dying breath.
After founding a team of asskicking awesome god-busting damsel-saving elite heroes, Buff trained and upgraded his powers to the max, and then came back in time to his parents' deaths, to mourn them once more, replacing his past self in the streams of time so this paragraph never actually happened. This sudden discrepancy and differences in power is referred to forever as "getting buffed".
Repeating the process indefinitely actually made Buff so strong that his rune awakened its true form: the Ultimate Blade of Ruination. Buff would go on to perform several mythological feats which I shall not expand upon.
Buff McStrongmuscles, the Patron Saint of All Things Awesome is a custom champion.
