They need to call in the Jaegers!
Actually they wouldn't even be big enough would they
oh my loving god
you did not
you DID NOT
I wi-
YOU HAVE CALLED UPON THINE FURY

The shortest jaeger is 50ft taller than godzilla
Godzilla lacks any form of EMP-type weaponry, therefor there is no need for a nuclear Tier 1 jaeger, outdating Gypsy Danger. Strike Eureka comes in with it's "brass knuckles" and sting blades, chest launcher, and Godzilla is loving down for the count
Any of the 5 listed jaegers make godzilla look like a kitten
I'm worked up and I loving LOVED the jaegers so now I have to justify my jaegers.
Striker Eureka is a Mark-5 with an electronic power-system: the one flaw that crippled it against Leatherback in Pacific Rim. Striker Eureka was the final and last jaeger ever built, and thereby also the strongest. Those wings on the back? Those are the T-16 Angel Wings. They allow it to keep it's balance when it's going faster than ANY other pre-dated jaeger. And those loving fists? Yeah. You thought Cherno Alpha could pack a punch, OHOHOHO back the forget up, Striker's fists are a "temperature-resistant brass/steel compound", and each finger is individually cased in it's own shell. Think that's not enough? Sting blades mother-forgeter, the blades are laced with carbon nano-tubes that contain thermal energy, setting the blades at 300°F+, hot enough to slice through a kaiju AND cauterize the wound.
Still not enough? loving anti-kaiju missiles IN IT'S CHEST. That's like 6 pairs of missile-firing-nipples staring at you. And it can fire it 3 times. That's 18 missiles. Holy stuff. How much more do you NEED?

Don't even bother to respond I know you're in awe, this is about as cool as mechs get.
