Synopsis for "Arena for Three!"
As Godzilla and Yetrigar's battle rages on in the Grand Canyon, Robert arrives in the Red Ronin robot to try and stop the two beasts from fighting each other. While Robert has the Ronin protect some rafters from falling rocks, the two monsters battle on. While elsewhere, the SHIELD Godzilla squad continues to make repairs to their damaged helicarrier and Dum Dum and Gabriel travel in a ship to try and keep track of Godzilla.
While back at the Grand Canyon, Robert is unable to make the two monsters stop fighting, and in order to prevent Yetrigar's rampage from escalating, he is forced to use the Red Ronin robot to kill Yetrigar by burying the beast in an avalanche. During the confusion, Robert allows Godzilla to slip away, however the fact that he had to kill in order to protect Godzilla weighs heavily on the boy.
This issue is reprinted in Essential Godzilla, Volume 1.
Yetrigar appears next in West Coast Avengers v.2 #32.
