If you look at serebii’s latest episode pictures, Tyrunt is really really big. It’s like, six times larger than Dedenne.
That… sounds about right to me. Tyrunt’s height is listed in the Pokédex as about 80 cm, and if that’s height at the shoulder, which seems likely, he’s probably over a metre long. Dedenne is only 20 cm from head to toe.
