Transformers Encore 23 Fortress Maximus
Fortress Maximus’ inexhaustible courage is tempered by his preoccupying desire for peace.
The toy has 2 alternate mode configurations, transforming into a relatively compact city and battle station modes as described in the US instructions.
The Japanese instructions rebrand the latter as a starship mode and it is the default mode for Fortress Maximus in the Headmasters animated series.
Additionally, the 1987 Hasbro toy catalog features a mis-transformed Fortress Maximus in a mode referred to as an impenetrable fortress, essentially consisting of his city mode with the legs splayed outwards.
