Rygar

Jack?
Oh, Jack! He calls himself “Rygar” now, and he sleeps in his basement under a pile of old towels.
Until… he wakes up… senses… INTRUDER!
“Come on out, Jack,” said his landlord, nervously twiddling his keychain. “We need to talk about you tapping the Smith’s cable line.”
“RYGAR ANGRY!” shouts Jack, and he searches his towel-pile for weapons.
“I’m sure you are,” said the landlord. “We’ll discuss this when you’re ready, okay?”
The landlord sighed and reminded himself that of all his tenants, Jack paid his rent on time.
And in cash.
“Grondar Goldheart happy,” growled the landlord, chuckling.
