Top Dog: Krypto vs. Ferris vs. Hulk dogs.

Krypto vs Fenris vs Pack of Gamma dogs from 2009 Hulk

50 foot tall ceiling over a neighborhood.

Krypto can fly around but it's gonna be where they can still reach him.

Whose the last team standing?

Hulk was in 2003.

Havent seen Superman yet, but in pretty sure Krypton wins.
You forgot about Cosmo from GotG btw 😉
And does the Inhuman series have Lockjaw?
And then there is Ralph from the Rampage movie.

My bad, 2003.

I don't think Cosmo would do well in a dog fight. Or it wouldnt be fair with the tk and all.
