Underdog

[Dennis]

Underdog learned the hard way not to pee on Godzilla's rug.

[Mr. DS]

Godzilla was in the mood for a hot dog.  (groan)

[Texdar]

Godzilla's leash did not please the dog.

[Goji_girl]

Sure, he's mad now, but wait until he sees the surprise he left in his roses!

[Joe the Destroyer]

Toho's crossover ideas hit rockbottom.

The kaiju's version of the FHM's segment, "Who the Hell are You!?"

[Shadow]

The JDF's latest super weapon turned out to be an unmitigated disaster. Rather than engage Godzilla in battle, the colossal biodroid codenamed MechaDog (but affectionately referred to as Dogora), caused havoc by lifting its leg and urinating on Tokyo Tower, sniffing Anguiras' butt and then ran off, chasing Mothra after one blast from Godzilla's atomic breath. The disgraced defense minster promises to have a full battalion of Masers back on the front line by day's end.

Some crossovers work very well, some crossovers just fail like the Virtua Boy.  This is the later of the two.

Even Godzilla was upset with the idea of a live action Underdog.

[Yaddo 42]

Despite it not being the cuisine of his native land, Godzilla needed the work, so he began to use his natural gifts to prepare giant mutant hounds for banquets and special occasion catering.
