Gok, in that image, Seaspray/Monty is clearly larger than Windcharger, Beachcomber, and Pipes - three toys from the modern "era" of Transformers design. The only other recent toy is probably someone like Brawn (and hence Outback).

In that paradigm, Seaspray is somewhat of an anomaly - larger and heftier than other toys in his "weight division".

The fact that he is comparable (in terms of size and weight) with Shortround and Breacher - a twelve year old and eight year old toy respectively - is remarkable.
