Throg

Throg is a frog who wields a sliver of Mjolnir, granting him the power of Thor in miniature. He is a member of the Pet Avengers and serves as the amphibian champion worthy of Asgardian might.

Few characters in Marvel history have carved out such a delightfully unexpected niche as Throg — a frog who wields the power of Thor. Debuting in 1986's Marvel Age Annual #2 under the legendary creative hands of Roger Stern and John Buscema, this Copper Age oddity has somehow endured for nearly four decades, popping up across titles like Thor, Thor by Donny Cates, and Lockjaw & the Pet Avengers: Unleashed. Throg shares his adventures with some remarkable company — Thor Odinson himself, the teleporting Lockjaw, the falcon Redwing, and Simon Walterson among them — which tells you everything about the wonderfully strange corner of the Marvel Universe this little amphibian inhabits. With a collector-significant key issue to his name and 28 catalog appearances spanning 1986 to 2025, Throg is proof that Marvel's heart is big enough to make you genuinely root for a frog with a mighty destiny.
